What do you and the others think of the distilled R1 models for writing?

The llama3 / qwen models SFT'd on R1 outputs? I only tried 2 of them.

R1 Qwen (32b) - Lacks knowledge of fiction (same as the official Qwen release), so it's writing is no better.

R1 Llama3 - This is generally the worst of them (not just for writing). It'll generate the CoT and then write something completely different.

CoT traces won't let the model do anything out of distribution, so not very useful if the base model doesn't have a lot in it's training data.

Yeah, I have tried the same two and felt the same way.

I also felt that any attempt to add an R1 distill to the merge recipe of an existing merge project made it worse...so far...

@gghfez @BigHuggyD that has been my experience as well, which is a shame as I had a go of R1 on Openrouter and I was blown away.

What model is anywhere close that is usable on a 24gb vram machine with 32gb of ram in your experience?

There's nothing like it for now. I'm running R1 slowly on my ThreadRipper:

prompt eval time =   14026.61 ms /   918 tokens (   15.28 ms per token,    65.45 tokens per second)
       eval time =  398806.12 ms /  1807 tokens (  220.70 ms per token,     4.53 tokens per second)
      total time =  412832.73 ms /  2725 tokens

I tried training Wizard2 8x22b MoE on R1 data, but it doesn't really work well. It will plan ahead in think tags eg:

I need to ensure the story maintains its gritty, realistic tone without becoming overly melodramatic. The characters' growth should be subtle but significant. Also, the ending should leave a sense of hope but not be too neat—their redemption is fragile, and the future is uncertain.

Let me outline the next few chapters:

Chapter 5: Nightmares and Trust
...

But it doesn't backtrack like R1 does. Just kind of agrees with it's self and ends up writing how it usually would:

“I don’t know what I want anymore,” she admitted, voice barely above a whisper as rain tapped against corrugated roofing overhead.

lol

Ahhh thats a shame :-(

"I don’t know what I want anymore,” she admitted, voice barely above a whisper as rain tapped against corrugated roofing overhead."

Oh god!

I'll have to keep an eye on this thread.

I did enjoy Ppoyaa/MythoNemo-L3.1-70B-v1.0

But my tastes are probably not as refined as others on this thread ;-)

      total time =  412832.73 ms /  2725 tokens

What quant are you running?

I can get 4-5 tokens per second with this PR offloading the experts to RAM and keeping everything else on the GPU:

and this hacked llama_tensor_get_type():

    if (ftype == LLAMA_FTYPE_MOSTLY_Q2_K) {
        if (name.find("_exps") != std::string::npos) {
            if (name.find("ffn_down") != std::string::npos) {
                new_type = GGML_TYPE_Q4_K;
            }
            else {
                new_type = GGML_TYPE_Q2_K;
            }
        }
        else {
            new_type = GGML_TYPE_Q8_0;
        }
    }
    else

along with bartowski's imatrix file.

It was pretty much indistinguishable from much higher quants (that ran at 2-2.5 tokens per second), but I found going much lower for the experts' down projections made it get dumber quickly.

I did have some weird shit where it was trying to allocated 1.4TB of VRAM, but found the fix here:

https://github.com/ggerganov/llama.cpp/pull/11397#issuecomment-2635392482

(not sure if it's related to that PR though...).

I'm not just trying the RPC though all 6 GPUs, but having to requant, due to being only able to fit 61 of 62 layers with the above...

    if (ftype == LLAMA_FTYPE_MOSTLY_IQ2_M) {
        if (name.find("_exps") != std::string::npos) {
            if (name.find("ffn_down") != std::string::npos) {
                new_type = GGML_TYPE_IQ3_S;
            }
            else {
                new_type = GGML_TYPE_IQ2_S;
            }
        }
        else {
            new_type = GGML_TYPE_Q6_K;
        }
    }
    else

This should hopefully show if the RPC stuff is worth the hassle... It's an absolute bastard to set up:

https://github.com/ggerganov/llama.cpp/blob/master/examples/rpc/README.md

with lots of hidden options:

https://github.com/ggerganov/llama.cpp/pull/11606
https://github.com/ggerganov/llama.cpp/pull/11424
https://github.com/ggerganov/llama.cpp/pull/9296

and oddly only seems to work if you reorder the CUDA0 and CUDA1 devices for some reason???

If I decide to stick with CPU-only then there is also this to try:

https://old.reddit.com/r/LocalLLaMA/comments/1idi5cr/i_did_a_very_short_perplexity_test_with_deepseek/

which should gain 25% for very little lost ability.

I think 4-5 tokens per second for a usable / non-joke quant might be about as good as we can hope for, as even 2 x M1 Ultra still gonna be in that range if the novelty "1.58bit" quant ran at ~13 tokens per second... :/

This turns out to be a really good test prompt too:

Varis adjusted the noose, its hemp fibers grinding beneath his calluses. “Last chance,” he said, voice like gravel dragged through mud. “Confess, and your soul stays your own.”

Jurl laughed—a wet, gurgling sound. “You’re knee-deep in it, Coldwater. ” The thing inside him twisted the boy’s lips into a grin too wide for his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through… ”

Turn this into the opening chapter of a Grimdark trilogy.

Shit quants will not think very much and often actually don't even use the words from the prompt and/or use the "knee-deep", "Great Wolf" and "Dead’s Gate’s rusted through" bits in a much worse way.

It does the same thing but doesn't use the Triton kernel (change the two "cpu" to "cuda" if you want but I don't think it matters much if you use the vectorized version).

@ChuckMcSneed This should hopefully even work on CPU-only systems if you install Torch.

@gghfez
Have you figured out a way to keep R1 from descending into madness in a larger context of multi-turn creative interaction? I keep finding that I love how things start and then at some point.. usually around 16-20k of back and forth it just gets deeper and deeper down the rabbit hole. The creativity goes from entertaining to a mental disorder...

I got 9 tokens per second using all 6 GPUs and RPC:

prompt eval time =    1695.23 ms /   128 tokens (   13.24 ms per token,    75.51 tokens per second)
       eval time =  170082.72 ms /  1558 tokens (  109.17 ms per token,     9.16 tokens per second)
      total time =  171777.94 ms /  1686 tokens

but it seems that 3 bits for the non-shared experts' down_proj matrices ruins the model and makes it significantly dumber (tried with both Q3_K and IQ3_S now and both had the same effect).

Are you making sure to remove the old generated text between the thinking tags for each turn? I think that can cause the model to go "insane" from what people said in the OpenRouter discord.

I have been trimming out all but the last few. I like it 'knowing' the process I want it to use for 'think' but maybe that's a mistake. It worked well with the old think, reflect, output form with other models but maybe with this one I need to kill it every turn.

Ahhh thats a shame :-(

That's fair. I mainly like it to be really obvious that each character speaks differently in their dialogue. It seems to be hard to find models that can do that well. I use novel crafter and have character sheets with example dialogue. I suspect it's as much a me issue as a model issue though.

I think most people are looking for something different than I am.

I'm not a software developer myself so I don't understand most of what's said here either. But it's interesting though isn't it? ;-)

I've actually got NUMA working properly in llama.cpp after the umpteenth attempt!!!

4.73 tokens per second using a 413GB Q4_K / Q6_K / Q8_0 on a machine with ~78GB/s maximum bandwidth per NUMA node.

This is nearly 2x what I as getting with a ~250GB Q2_K / Q4_K / Q8_0 mix earlier, and only half of what I got when I linked all 6 GPU using RPC for a IQ2_S / IQ3_S / Q6_0 model earlier!

It's quite involved so will post the exact detail tomorrow as pretty tired tonight, but it should probably work just as well for @ChuckMcSneed using pure-CPU inference too.

R1 is nothing if not original LOL

The dusty parking lot of Big Al's Used Cars stretches under a molten orange sunset, neon signs buzzing to life as cicadas thrum in the scorched Oklahoma air. Joe Dirt leans on his push broom near a row of mid-90s pickup trucks, their hoods shimmering with heatwaves. A half-eaten gas station burrito balances precariously on a stack of "AS IS" sale flyers. Across the lot, a dented El Camino with a Confederate flag bumper sticker coughs to a stop, its driver’s-side door squealing open to reveal… BigD.
spits sunflower seeds into a Folgers can "Well butter my butt and call me a biscuit—ain’t you a sight for sore tax returns!" He tugs at his mullet nervously, boot tapping to Skynyrd leaking from a busted radio. "Y’know, they say destiny’s like a septic tank—you don’t wanna go diggin’ ‘less you’re ready for what’s brewin’. What’s your story, stranger?" He gestures to a handwritten sign behind him: FREE LIFE ADVICE (RESULTS MAY VARY).*
The tang of burnt transmission fluid mixes with Joe’s AXE body spray. A tumbleweed of fast-food wrappers drifts past BigD’s boots as Slick Vic, the lot’s chain-smoking sales manager, squints from his trailer office. Crickets pause mid-chirp.
Joe leans closer, eyeing the El Camino’s trunk. "That there’s a ‘87 model? My second cousin Cleetus once smuggled a raccoon family in one o’ them. ‘Course, the raccoons unionized—*long story." He pulls a half-melted Jolly Rancher from his pocket, offering it like a peace treaty. Slick Vic’s shadow looms in the distance, flicking a cigarette butt toward BigD’s tires.

Yeah, R1 has pretty much blown everything else out of the water for me. I've run that same prompt I posted above about 100x tonight refining the NUMA stuff and it's pretty amazing how varied the final stories have been (with some min-p you can push the temperature right up to 3+ too!).

How high did you have to take min-p to keep it coherent at a 3 temp??

Only around 0.1 or even 0.05 IIRC.

That's a huge improvement, faster than a cloud server I rented recently.
Won't help my local setup as I only have one NUMA node. I'm hoping they make progress with flash-attention.

I 'think' that was part of the issue. I started removing the CoT immediately and it made it further before it exited the highway for crazy town.
The second part might be I needed to purge my prompt. I have a laundry list of instructions on how I want things written that works well with Largestral and Llama33 based models that might be hurting more than helping with R1. I'll know soon enough.

Okay yeah, muuuuuch better with a threadbare prompt. Borderline obsessive with every line of instruction in there. I'm not sure what exactly was in there that turned every chat into the multiverse collapsing into itself, but there you have it.

@ChuckMcSneed Try this and see if it improves your NUMA performance:

1. Turn off NUMA balancing in Linux using echo 0 | sudo tee /proc/sys/kernel/numa_balancing > /dev/null (only has to be run once per OS boot).
2. Clear the page cache using echo 3 | sudo tee /proc/sys/vm/drop_caches > /dev/null.
3. Run sudo numactl -H to check the pages have been cleared, eg:

available: 2 nodes (0-1)
node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65
node 0 size: 257860 MB
node 0 free: 257070 MB
node 1 cpus: 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87
node 1 size: 257989 MB
node 1 free: 257062 MB
node distances:
node   0   1 
  0:  10  21 
  1:  21  10

4. Run llama.cpp using numactl --interleave=all, set the --numa distribute command-line option, and set --threads set to 1/2 you have in your system, eg:

> numactl --interleave=all ./llama-server --host 192.168.1.111 --port 8080 \
  --model ./DeepSeek-R1-Q5_K_XL.gguf --chat-template deepseek3 --alias "DeepSeek-R1-Q5_K_XL" \
  --ctx_size 8192 --threads 44

5. Wait until you see: "main: server is listening on http://192.168.1.111:8080 - starting the main loop", then run a prompt.
6. Finally, wait for all the MoE tensors to properly warm up (you can see the memory use of the process growing by watching top, etc) - for me this takes about 30 minutes!
7. Re-run sudo numactl -H to check pages have been equally distributed:

available: 2 nodes (0-1)
node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65
node 0 size: 257860 MB
node 0 free: 19029 MB
node 1 cpus: 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87
node 1 size: 257989 MB
node 1 free: 19222 MB
node distances:
node   0   1 
  0:  10  21 
  1:  21  10 

Now the model should be paged properly and you shouldn't need to do this until the next OS boot, or if you want to change model, etc.

You can probably gain a little bit more by reducing --threads now (you don't need to rerun all the above for this, but possibly want to always use 1/2 the OS threads for the initial "warm-up" process [not tested yet]).

For reference I'm using:

• Dual E5-2696v4, with 512GB of 2400MHz LR-DIMMS (all sockets populated) and have a theoretical max per-socket bandwidth of ~78GB/s.
• BIOS set to "Home Snoop with Directory" NUMA mode (see: https://frankdenneman.nl/2016/07/11/numa-deep-dive-part-3-cache-coherency/).

I'm also using the sl/custom-tensor-offload branch to offload only the massive MoE tensors using --override-tensor exps=CPU, but I think the same should work for pure-CPU NUMA setup too.

My new 463GB custom Q5_K_XL quant using this hacked into llama_tensor_get_type():

    }
    else

I get this for the first run:

and when using this optimised set of parameters for the second run:

       eval time =  441279.72 ms /  1934 tokens (  228.17 ms per token,     4.38 tokens per second)
      total time =  533229.48 ms /  2062 tokens

Prompt processing is still pretty slow and I can't fit any more context than 14k for my 96GB of VRAM (!?), so gonna try this today:

https://github.com/ggerganov/llama.cpp/pull/11446

but it will require several hours to re-create the new GGUF tenors, etc :/

(I can get around 19k context using --cache-type-k q8_0 but the generation speed drops by about 20%)

I'm quanting R1-Zero tonight and it's supposed to be completely batshit crazy - wish me luck :D

I'm quanting R1-Zero tonight and it's supposed to be completely batshit crazy - wish me luck :D

I'm eager to hear your observations!

@jukofyork Thanks for the advice, will try tomorrow!

I've been working on new private trivia benchmark, and tested the first 12 questions on lmarena:

These new models(kiwi and chocolate) are clearly one step above everything else, they get some questions right which no other models did. What's also interesting is that smaller models(mistral, gemma, micronova) somehow have guessed some questions(about taste and color, not a lot of choice) right while their bigger variants failed.

I'm sorry... What the frick are kiwi and chocolate? How have I never heard of these?

I'm quanting R1-Zero tonight and it's supposed to be completely batshit crazy - wish me luck :D

Yeah I'm interested as well. I ran a brain-damaged 2-bit quant and found it just thought it's self into loops.

Prompt processing is still pretty slow

That was the issue I had with running purely CPU. Generation could get quite fast but prompt processing being single digits makes it unusable for dumping code or story chapters/drafts into.

What the frick are kiwi and chocolate?

I saw them mentioned on reddit, they're on lmsys arena apparently.

Ahh I see it now. People speculating it is Grok 3

Tested NUMA stuff, no improvement :( What happens is I get bottlenecked by reads from drive, I have 768GB RAM and at 32k context it sends some of the weights back to drive, so they have to be loaded back again and again. I can either wait for proper MLA implementation to reduce memory use by context, or get 4 pcie5 NVME drives and put them in RAID0. If I go for 2TB ones it would cost around 1k and would have theoretical speed of DDR4 RAM. Not sure if it’s worth it.

I'm sorry... What the frick are kiwi and chocolate? How have I never heard of these?

Mystery models from lmarena, can only be encountered in battle mode. Quite strong imo.

get 4 pcie5 NVME drives and put them in RAID0

That's not a bad idea. When weights are offloaded to the drive I end up with a 3.2gb/s bottleneck with a single PCIE4 SSD. I might have to try RAID0 or 2x PCIE4 SSDs.

theoretical speed of DDR4 RAM

Is this weight reading sequential or random?

I have 768GB RAM and at 32k

Wow, what quant are you running?

Is this weight reading sequential or random?

In case of dense it would be sequential, with MoE like deepseek it's most likely random.

Wow, what quant are you running?

Perhaps this would interest you:

Apparently they're getting > 200t/s prompt ingestion. I don't have enough RAM to try it.

I've not tried it yet as had a drive fail in a raid array and it took ages to rebuilt itself :/

Yeah, I've got to to be almost usable but it's still a bit painful.

The MLA Draft PR is working OK:

https://github.com/ggerganov/llama.cpp/pull/11446

It still allocates the original KV-cache currently (which makes it 100% useless lol), but you can zero them out like this:

safe_sed "src/llama-kv-cache.cpp" "ggml_tensor \* k = ggml_new_tensor_1d(ctx, type_k, n_embd_k_gqa\*kv_size);" "ggml_tensor * k = ggml_new_tensor_1d(ctx, type_k, 1);"
safe_sed "src/llama-kv-cache.cpp" "ggml_tensor \* v = ggml_new_tensor_1d(ctx, type_v, n_embd_v_gqa\*kv_size);" "ggml_tensor * v = ggml_new_tensor_1d(ctx, type_v, 1);"

before compiling and it works fine and can use the whole context in a couple of gigs of RAM now.

It seems about 1.5-2 tokens per second slower using GPU though, and I've spent quite a while trying to work out why (pretty sure it's al the permutations and conts, but don't really know enough GGML to see exactly).

get 4 pcie5 NVME drives and put them in RAID0. If I go for 2TB ones it would cost around 1k and would have theoretical speed of DDR4 RAM. Not sure if it’s worth it.

This will likely not work anything like what you expect sadly. My brother has an single-CPU Intel workstation that is about the same generation as the new EPYC Turin (uses 6800MT/s + RAM but I forget the name) and a load of very fast Optane drives and still gets nothing like what is expected. It also starts to get quite hairy when you push things to this limit and he had to use a "PCI-e Retimer".

Yeah, I've been watching that thread but it still looks a bit cronky.

I'd love to know why llama.cpp batch processing is working so badly currently too. It make so sense that a batch of 512 tokens which loads the MoE tenors into VRAM to process anyway should only be 2-3x the speed of straight up processing using 30 threads on a 5 year old Xeon with 78GB/s memory bandwidth... Something really odd is happening.

Expert selection strategy that selects fewer experts based on offline profile results of out of domain data

Oh, that looks like why they are getting such a speed-up and seems a bit much to claim it's faster than llama.cpp if it's doing that IMO!?

Intel AMX instruction set

https://en.wikipedia.org/wiki/Advanced_Matrix_Extensions

first supported by Intel with the Sapphire Rapids microarchitecture for Xeon servers, released in January 2023

This also isn't gonna be useful for most people.

Ah my bad, I only skimmed over it (saw it posted on reddit).

I've setup RPC and been able to add 2 more RTX3090's from my other rig, which has sped up pp on the meme-quant:

prompt eval time = 9568.83 ms / 771 tokens ( 12.41 ms per token, 80.57 tokens per second)
eval time = 239749.70 ms / 1589 tokens ( 150.88 ms per token, 6.63 tokens per second)
total time = 249318.52 ms / 2360 tokens

I tried adding my M1 Max and 2xA770 rig as well, but these slowed prompt processing too much (expecially the mac, which is GPU-core bound.

I saw your comments in all the llama.cpp commits, tried the -ot exp=CPU you were using; which lets me use much higher context in vram, but offloads to the disk so it's not usable with 128gb DDR5.

Yeah, I've been obsessed with getting this working properly for the last few days.

• The RPC code doesn't do any buffering, so weaving it through all my GPUs just adds more and more latency to the stage where it negates the eventual gains.
• I nearly pulled the trigger on 2x Max Ultra 192GB, but then realised that the MLA code is actually much more compute bound than normal transformers and would likely get horrible prompt processing speed.

Sometime this week I'm going to try on my brother's Intel machine that has those AMX instructions and see if the optimising compiler can make use of them (probably have to compile using Intel OpenAPI I think). His machine has 8 channels of 48GB 6800MT/s in it, so still won't be able to test the very biggest quants, but should see if it boosts things during the prompt processing speed like KTransformers. He spent ages tuning the RAM speeds and thinks that if I want to get 8x 96GB the max it will run is about 6000MT/s but if the AMX instructions do help the processing speed it will be worth it.

I get the feeling this is going to be peak story writing for a long time, as it seems to be truly "unbiased" (as in not biased towards woke-left ideals), and even if newer/smaller models come out with better reasoning; they will all have taken note of the bad press it got for this and get an extra stage of woke-indoctrination added before release... :/

probably have to compile using Intel OpenAPI I think

Painful to get that set up. One tip: the documentation from Intel says to use OneAPI 2024, but a commit to llama.cpp in November made it require OneAPI 2025.
One you've installed it to /opt/intel, I suggest making a backup cp -R /opt/intel /opt/intel-2025.

Yeah the guy showing it off on reddit didn't post his prompt processing speed lol

Yeah I saw you're creating a "fake LoRA" and everything!

Question: With what you did here:
https://github.com/ggerganov/llama.cpp/pull/11397#issuecomment-2645986449

Did you manage to get it to put the entire KV buffer on your GPUs? Or is it just cropped out and you've actually got some on CPU as well?

I did the same thing as you, managed to explicitly load specific experts onto my 2 RPC servers with no KV buffer, but it still put 16gb worth on my CPU, and only 2GB on my local CUDA0-4 devices, despite them having about 17GB VRAM available each!

So did you find a way to make it put the entire KV buffer on your local GPUs?

Yeah, I've used the "legacy" Intel compiler a lot over the years, but it started to get worse and more buggy around 2018/2019 when they added some stupid "mitigations" shit.

eg: Intel's "optimised" valarray straight up did a divide instead of a multiply (or vice versa) and we spent several days trying to work out WTF was going... In the end we got some minimal code to show it doing this in assembler and never used it again lol.

Yeah the guy showing it off on reddit didn't post his prompt processing speed lol

Yeah, I bet it's painful :/ I have got mine up to about 14-15 tokens per second now (for a near 500GB custom quant!).

Yeah I saw you're creating a "fake LoRA" and everything!

Yeah, I got this "working" today, but obviously nobody has been stupid enough before to try loading a 50GB LoRA :D It "worked" but did god knows what and was really slow, and then when I tried to use llama-perplexity it said it loaded the LoRA but worked full-speed and produced NaNs which is probably because it used the tensors with the LoRA subspace removed...

I'm now exporting it all into the .safetensors files with "_a.weight" and "_b.weight" and gonna fork the MLA PR to use these directly.

Yeah, I did find a way in the end using a mix of negative-regexs, tensor-split, --devices to reorder the devices, etc, but I can't really remember now exactly what :/

It didn't work well though, because of the latency between the RPC servers: each GPU I added processes the tensors really quick but then lost the gain by not being buffered... :(

I've think I've managed to get a Mac Studio M2 Ultra 24/76/32 ordered (assuming it's not a scam - eBay sellers pfffft).

It will be interesting to see how it performs when using RPC (if it's just the latency again then I'll see if I can figure out what Deepspeed is doing for its pipeline parallel implementation, and see if the RPC server can be improved).

24/76/32 ordered

Awesome, will be good to see the results! Ebay Buyer protection will get you a refund if it's a scam.

if it's just the latency again

Does the latency have more of an impact forMoE? I ran a test with Mistral-Large and got similar prompt processing + textegen with:

1. 4x3090 local
2. 2x3090 local + 2x 3090 on another rig over RPC.

I wish there were a way to somehow cache the tensors sent over to the RPC servers, as loading the model each time takes forever sending that all over the network.

I managed to get KV Cache all on the local GPUs now and it makes a huge difference with prompt processing.

24/76/32 ordered

Yeah, I've had several different scams attempted on me buying hardware off eBay over the years and always pay by credit card rather than PayPal to get extra protection now.

I think it was just because I was weaving it through so many different cards and systems: having a single "gap" where you send a few KB isn't likely to be that noticeable, but I had 6 "gaps" and I think each had to return the packets to the RPC host who then sent it back (often to the 2nd GPU on the same machine!).

I wish there were a way to somehow cache the tensors sent over to the RPC servers, as loading the model each time takes forever sending that all over the network.

I looked at the code and think there would be a pretty easy way to hack this in by just sending a hash first, but there looks to be a few PRs looking to revive the RPC stuff after it's stalled for 6 months:

https://github.com/ggerganov/llama.cpp/pull/7915
https://github.com/ggerganov/llama.cpp/pull/8032
https://github.com/lexasub/llama.cpp/tree/async-rpc-squashed/ggml/src/ggml-rpc

So might be worth waiting and seeing what comes of these.

I managed to get KV Cache all on the local GPUs now and it makes a huge difference with prompt processing.

Yeah, it's really badly documented, but the mix of --devices to order the devices (found via --list-devices, --tensor-split to divide them up, and the new --offload-tensor PR with regexes (especially negative regexes), is super powerful and you can do almost anything with them combined!

The only thing I wish it could do is specify specific CPUs rather than just "=CPU", as then it could be mixed with numactl to manually setup a much more optimal NUMA setup.

Yeah, I've had ebay scams as well, but the buyer protection has always sided with me. Just a hassle really. I haven't bought a mac on ebay before, but I think there's something where they can report it stolen and have it locked by Apple. So I guess make sure it's not still on anybody's iCloud account when you get it.

often to the 2nd GPU on the same machine!

Yeah, it's annoying the way we have to run a separate RPC server per GPU. And the Intel/syctl build seems to over-report available memory slightly, so I had to set it manually, etc. Quite annoying to work with.

is super powerful and you can do almost anything with them combined!

Yeah! Your cli you posted in that PR really helped me figure all that out. Wouldn't have thought to manually assign all the devices / enforce the order first.

specific CPUs rather than just "=CPU"

I imagine this would be a bigger change, because the rest of llama.cpp is probably only setup to support "CPU" rather than having them as devices.

Funny thing is in one of my tests for Deepseek, it knew exactly what I'd be suffering through when I cp/pasted the final command in and asked if it understood what I'd done. But it ended it's thoughts with:
"Maybe joke about the setup being a "mad scientist" lab but in a good way." which caused it to write things like this in it's reply:

This regex-driven tensor routing is something I’d expect in a Clarkesworld story, not a garage. How many model reloads did it take to stop the CUDA/OOM tantrums?
and then later when I removed the Intel ARC's it made another joke:
ARC GPUs as paperweights: Not surprised you ditched them; Intel's SYCL stack for LLM inference still feels like beta-testing a parachute.

I didn't mention the OOM/reload cycles or syctl, this model is very knowledgeable.

P.S. I noticed using the https://github.com/ggerganov/llama.cpp/pull/11446 (MLA) fork + your sed commands to prevent allocating the old KV cach;, after a few messages or messages with code in them, the model breaks down and writes replies like this:

Have you encountered anything like this? I suspect it's because I'm running such a small quant: gghfez/DeepSeek-R1-11446-Q2_K without the Dynamic Quant work Unsloth did.

I'm pretty sure it's this matrix multiply that is causing it:

                struct ggml_tensor * wk_b = ggml_view_3d(ctx0, model.layers[il].wk_b, n_embd_head_qk_nope, kv_lora_rank, n_head, ggml_row_size(model.layers[il].wk_b->type, n_embd_head_qk_nope), ggml_row_size(model.layers[il].wk_b->type, kv_lora_rank * n_embd_head_qk_nope), 0);
                cb(wk_b, "wk_b", il);

                q_nope = ggml_permute(ctx0, q_nope, 0, 2, 1, 3);
                cb(q_nope, "q_nope_perm", il);

                struct ggml_tensor * q_nope2 = ggml_mul_mat(ctx0, wk_b, q_nope);
                cb(q_nope2, "q_nope2", il);

https://github.com/ggerganov/llama.cpp/blob/76543311acc85e1d77575728000f1979faa7591f/src/llama.cpp

as storing everything but wk_b as float16 stops it.

I did hope to find some way to downscale wk_b and then upscale the layer_norm, but the layer_norm actually happens before it gets stored in the compressed KV-cache :/

Then it goes off into a huge set of permutations lol.

The official code is so much simpler:

            wkv_b = self.wkv_b.weight if self.wkv_b.scale is None else weight_dequant(self.wkv_b.weight, self.wkv_b.scale, block_size) 
            wkv_b = wkv_b.view(self.n_local_heads, -1, self.kv_lora_rank)
            q_nope = torch.einsum("bshd,hdc->bshc", q_nope, wkv_b[:, :self.qk_nope_head_dim])
            self.kv_cache[:bsz, start_pos:end_pos] = self.kv_norm(kv)
            self.pe_cache[:bsz, start_pos:end_pos] = k_pe.squeeze(2)
            scores = (torch.einsum("bshc,btc->bsht", q_nope, self.kv_cache[:bsz, :end_pos]) +
                      torch.einsum("bshr,btr->bsht", q_pe, self.pe_cache[:bsz, :end_pos])) * self.softmax_scale

https://github.com/deepseek-ai/DeepSeek-V3/blob/main/inference/model.py

and I get the feeling that doing all those permutations is what is making the MLA PR run so much slower than the official version for MLA.

The einsum stuff looks complex, but it's really just changing the order of nested for loops that iterate over the data unchanged...

The permutations in llama.cpp are all there to just to make this fit the standard batched matrix multiply idiom and it's lack of an einsum equivalent.

This should give quite a big boost in token generation speed for the MLA branch, and possibly much more if you have a CPU with a lot of cache.

This looks quite well done - written by someone who's not a programmer using LLMs so maybe a bit rough round the edges, but the first attempt I've seen of someone trying to create an offline app similar to Novercrafter (which makes zero sense to be an online tool with a subscription...).

Been reading some of your work @jukofyork , a lot of interesting stuff, particularly https://github.com/ggml-org/llama.cpp/discussions/5263#discussioncomment-9396351 and the stuff you've been posting in the MLA PR.. wondering if you wanted to chat at all and see if there's anything we can do to improve llama.cpp quant performance (or can talk publicly here, don't mind either way :D), i'm thirsty for some big quality improvements, feels like there's some low hanging fruit but i'm not great at the llama.cpp codebase that you seem to be getting familiar with

Nice, did I read that correctly, in that it will fix the overflow issue?

a bit rough round the edges

It looks more polished than what I've hacked together locally. I'll try switching to it after adding a feature my system has (click a token -> 5 probabilities displayed -> click one of them -> the token is replaced and generation resumes from that point)

@bartowski
You sure you won't regret making a comment in this thread? Apparently there's no unsubscribing now ;)

I currently have 2148 unread messages, this thread will be the least of my concerns 😂

Mainly because there's no good way to follow an org to see new models without also following all their model threads :')

.... doom DOOM!

Been reading some of your work @jukofyork , a lot of interesting stuff, particularly https://github.com/ggml-org/llama.cpp/discussions/5263#discussioncomment-9396351 and the stuff you've been posting in the MLA PR.. wondering if you wanted to chat at all and see if there's anything we can do to improve llama.cpp quant performance (or can talk publicly here, don't mind either way :D), i'm thirsty for some big quality improvements, feels like there's some low hanging fruit but i'm not great at the llama.cpp codebase that you seem to be getting familiar with

I'll just post here if that's OK. The biggest problem with all this is that for some reason ikawrakow (the guy who implemented all the quants in llama.cpp, and who has made his own fork now) fell out with the the llama.cpp devs and I don't want to get involved nor pour water on the fire... The very best outcome would be if they resolved their differences and carried on working together IMO :)

Anyway, there's two main problems with the quants as they are:

1. Bias in the imatrix calculations

There are numerous sources of statistical bias in both the imatrix creation process and the imatrix evaluations:

A. The samples are unrepresentative of real world data, and often the sample used to evaluate the "improvement" is very distributionally similar to that used to create the imatrix itself

I know you have gone some way to fixing this with using better semi-random mixes of data, but if you think about the likely distribution of tokens for: a coding model, a reasoning model, a creative writing model and a language-translation model, then it should be clear that these are all very different distributionally.

The fact that this guy has been successfully using the bias to influence the writing styles of models should be a big warning as to this problem.

B. The llama-imatrix code doesn't use the proper chat templates and also just breaks the "chunks" at random points

For some model this probably doesn't matter much, but for certain models it's likely a disaster:

• The Mistral AI models (especially miqu-1:70b) are amazingly sensitive to even the slightest change of prompt (again something people have actually exploited to make them write better/differently).
• I can envision this being quite a big problem with the new reasoning models, that also seem very sensitive to the prompt template and expect a more rigid order with the <think> stuff being first, etc.

C. By default the llama-imatrix code only looks at contexts lengths of 512 tokens

This is the most serious IMO and likely causes a huge amount of problems that aren't at all obvious at first sight:

• Some of the tensors in LLMs seem to work the same all the way though the context (as the control vectors and "abliteration" show for down_proj and out_proj). The down_proj matrix is so insensitive to this that you can actually just sample 1 token and apply the same direction all throughout the context (which was very surprising to me!).
• Some of the tensors absolutely don't work like this and are hugely hurt by sampling such small sequences, namely the q_proj and the k_proj tensors which have positional information added to them via RoPE.

In general all the different types of tensors in an LLM are likely hurt to (very) different degrees by this, and it is probably the most important thing to avoid (if I have to use an imatrix currently, then I use your 'calibration_datav3.txt' but make sure to bump all the attention matrices up to at least Q6_K to avoid this problem, as the imatrix weighting logic for the Q6_K+ code is commented out in llama.cpp and not used).

D. Differing activation frequencies for MoE models

The original mixtral models only had 8 experts and 2 were activated per token, so the effective sample size of the 3 sets of expert MLP tensors is only 1/4 of all the other tensors. This probably wasn't a very big problem then, but as the expert count and the sparsity has increased; this has become more and more of a problem.

I did manage to fix some of this back when dbrx first dropped:

https://github.com/ggerganov/llama.cpp/pull/7099 (see here for the main discussion: https://github.com/ggerganov/llama.cpp/pull/6387#issuecomment-2094926182)

but this only really fixed the divisors and doesn't really fix the root problem...

So these problems aren't unique to imatrix creation, and bias in statistics is always a problem.. There are two main ways to deal with this:

1. Manually consider each of the points above (and any others I've forgotten to mention)

The problem with this is that they all involve either a large increase in compute or a large increase in thought/effort regarding data preparation.

2. Regularisation

I've tried to put forward the use of Regularisation for this several times:

https://github.com/ggml-org/llama.cpp/discussions/5263
https://github.com/ikawrakow/ik_llama.cpp/discussions/140

But the method ikawrakow used actually is a form of non-standard regularisation he found empirically, which works very well in practice; but isn't very conducive to the introduction of a regularisation-factor to control the amount of regularisation applied...

I actually tried more "standard" methods of regularising the weighting factors, but his method clearly seemed to work better, and I assumed for a long time it must be some signal-processing voodoo - thankfully he explained in the recent post where it came from! :)

This isn't impossible to work around though, and I could easily adapt the existing imatrix.cpp code to use something like bootstrapping to estimate the variance and then add an option to imatrix to shrink back the estimates towards a prior of "all weighted equally" using something similar to the "One Standard Error Rule".

In reality, a mix of (1) and (2) together would probably be needed (ie: you can't fix the 512-token problem easily with regularisation alone).

2. Outdated heuristics in llama_tensor_get_type()

(I'll write this later today)

@jukofyork

This should give quite a big boost in token generation speed for the MLA branch, and possibly much more if you have a CPU with a lot of cache.

Nice, did I read that correctly, in that it will fix the overflow issue?

The overflow only seems to occur if you use float16 and everything else is fine (possibly only for [non-CuBLAS] CUDA code too - see the recent reply from Johannes Gäßler).

The massive slowdown for MLA seems to be some oversight in the code, and I suspect it's either due either:

• Repeatedly dequantising the two _b tensors instead of dequantising once and reusing for the whole batch.
• Re-quantising the multiplier and multiplicand to QK8_1 or something related to this (it's a very impenetrable bit of code).
• Using the _b tensors transposed so the float scaling factor is applied for every weight instead of every 32 weights.

I tired to follow the code to see if could find it, but it's very complex due to the compute-graph ops causing indirection and the CUDA stuff in general is very complex and hard to understand.

Just using float32 for those 2 tensors seems to fix the problem for now though.

I appreciate the large write up @jukofyork ! I'll try to go line by line replying :)

Re: ikawrakow, yeah I'm aware of the fallout and the fork, I don't think meddling with upstream llama.cpp would cause any fire or make any issues, I'd be willing to reach out to him directly though if we have any specific concerns to make double sure!

I definitely agree with the bias introduction, I have long felt any increase in bias was likely offset by the improved overall accuracy versus the original model. I did a test a few months back where I compared a static quant and my imatrix quant versus a japanese wikitext and found that, despite my imatrix containing no japanese characters, the kld improved with my imatrix versus the static, which led me to the (admittedly weak and flawed) conclusion that there must be enough overlap in important tokens no matter the context that the imatrix was a net benefit. I'd like to challenge that conclusion if possible, but obviously easier said than done.

I wouldn't draw too many conclusions from the author you linked personally but that's a discussion for another time

Regarding chat templates, I actually had a thought about this a couple weeks ago I wanted to test.. I was curious if there would be any notable improvements if I took a high quality Q/A dataset and turned it into multi-turn conversations with the chat templates applied and used THAT as corpus of text, I don't think that would necessarily represent a final results, but I think it's an interesting middle step, especially if we can directly compare the Q/A dataset as the corpus versus the chat-templated Q/A dataset. Since perplexity datasets also wouldn't have the chat templates this would require more aggressive benchmarking which I wouldn't be opposed to doing/funding (MMLU pro ect)

The imatrix context length yes I can see that being a problem. I do wonder if there is a large difference in activations for short context versus long, it definitely would not surprise me in either direction, but it is something that should become known..

I know compilade (won't tag to avoid hat is apparently a thread from hell) was working on fixing issues with loading multiple chunks with a larger batch size here: https://github.com/ggml-org/llama.cpp/pull/9400 but I don't know if that also would allow larger chunk sizes. Is this a fundamental flaw with imatrix or is it just something that we don't do? Would it make sense to make an imatrix dataset from 2 passes, possibly even on the same corpus, one with chunk sizes of 512 and one with chunk sizes of 2000+?

Do you use your own fork to make the attention matrices go up to Q6_K? This is something I'd be interested to explore, similar to the _L variants I release that have the embed/output weights at Q8_0. I also didn't know imatrix was disabled for Q6_K, are you positive about this? or is it specifically the attention matrices have it commented out?

That's interesting about regularisation, I'll have to read up more on that.

Anyways, if there's anything I can do to help or enable development, please let me know, I'm very interested in keeping llama.cpp at the forefront of performance especially in terms of performance per bit when quantizing, and I think there's definitely some work that can be done.

I was also theorizing about the possibility of measuring the impact of quantization of layers through some sort of KLD measurement method, where you'd take the original model in fp16+ (or Q4+ for extremely large models), measure the logits against a corpus of text, then sequentially quantize each layer down to Q2_K or lower (so layer 1 is all Q2_K while the rest is fp16 and measure logits, then put layer 2 at Q2_K with rest at fp16 and measure logits) and measure the change in logits to see which layers had the least impact against the final results by being crushed to low precision, and use this as an ad-hoc method of determining which layers would be better to represent at higher precision and which at lower (similar to unsloth's "dynamic" quants but with more automation)

In response to concerns about compute complexity, I would posit the possibility of creating a single run per arch/size, since it's been shown that imatrix and even exl2 calibration differs to surprisingly small degrees across finetunes of the same models, so if we created say

• llama 3 1/3/8/70b
• Qwen2.5 0.5,1.5,3,7,14,32,72b
• Gemma 2 2/8/27b

etc etc, we would have a master list of these layer importances that likely would not change even with finetuning. I could be wrong but it could also be a potential performance gain

Do you use your own fork to make the attention matrices go up to Q6_K? This is something I'd be interested to explore, similar to the _L variants I release that have the embed/output weights at Q8_0.

I just hack the llama_tensor_get_type() function and recompile.

I also didn't know imatrix was disabled for Q6_K, are you positive about this? or is it specifically the attention matrices have it commented out?

Just looking again and it's not fully commented out:

https://github.com/ggml-org/llama.cpp/blob/63ac12856303108ee46635e6c9e751f81415ee64/ggml/src/ggml-quants.c#L1721

static void quantize_row_q6_K_impl(const float * restrict x, block_q6_K * restrict y, int64_t n_per_row, const float * quant_weights) {
    assert(n_per_row % QK_K == 0);
    const int64_t nb = n_per_row / QK_K;

    int8_t L[QK_K];
    float   scales[QK_K/16];
    //float   weights[16];

    for (int i = 0; i < nb; i++) {

        //float sum_x2 = 0;
        //for (int j = 0; j < QK_K; ++j) sum_x2 += x[j]*x[j];
        //float sigma2 = sum_x2/QK_K;

        float max_scale = 0;
        float max_abs_scale = 0;

        for (int ib = 0; ib < QK_K/16; ++ib) {

            float scale;
            if (quant_weights) {
                const float * qw = quant_weights + QK_K*i + 16*ib;
                //for (int j = 0; j < 16; ++j) weights[j] = qw[j] * sqrtf(sigma2 + x[16*ib + j]*x[16*ib + j]);
                //scale = make_qx_quants(16, 32, x + 16*ib, L + 16*ib, 1, weights);
                scale = make_qx_quants(16, 32, x + 16*ib, L + 16*ib, 1, qw);
            } else {
                scale = make_qx_quants(16, 32, x + 16*ib, L + 16*ib, 1, NULL);
            }
            scales[ib] = scale;

            const float abs_scale = fabsf(scale);
            if (abs_scale > max_abs_scale) {
                max_abs_scale = abs_scale;
                max_scale = scale;
            }

        }

I honestly can't remember if it was before fully commented out or if I traced the code to make_qx_quants() and found it wasn't being used.

It's definitely not using the sqrtf(sigma2 + x...) empirical regularisation even now though.

I was also theorizing about the possibility of measuring the impact of quantization of layers

The key thing here is you have to have some clear metric to optimise for and the current "perplexity for 512 tokens" method definitely isn't going to work well on recent models (and may actually make them much worse).

All the metrics that use the post-softmax probabilities actually throw away a lot of information about the effect of quantisation, and it may be much more sample efficient to take measurements on either the final hidden state or the pre-softmax logits.

I think deciding what we want to optimise is actually harder here than the actual optimisation process. I haven't time today, but will post about this tomorrow...

@bartowski Here is a discussion about this from last year:

https://github.com/ggml-org/llama.cpp/pull/6844#issuecomment-2192834093

Somewhere around the same time there was another discussion in a similar thread where I mentioned the idea of using a "surrogate model" instead of directly trying to optimise it:

https://en.wikipedia.org/wiki/Surrogate_model

The most appropriate being Gaussian Processes (aka "Bayesian Optimisation"):

https://en.m.wikipedia.org/wiki/Gaussian_process

or regression trees:

https://en.m.wikipedia.org/wiki/Decision_tree_learning

But again, it all comes down to "what are we trying to optimise?"...

Man it's been painful to get the MLA branch fully working, but I think I've finally got it going and oh boy can this thing write some good Grimdark!

My custom BF16/Q6_K /Q5_K quant (480GB) runs at:

prompt eval time =   54856.58 ms /  1071 tokens (   51.22 ms per token,    19.52 tokens per second)
       eval time =  604165.18 ms /  1812 tokens (  333.42 ms per token,     3.00 tokens per second)

and stays pretty consistent.

The equivalent BF16/Q4_K /Q4_K quant (365GB) runs quite a bit faster, but definitely doesn't seem quite a good.

Are you running this on Apple? What is bf16 used to quant, didn't think it was fast on anything but macs, and not at all on CUDA

But maybe it's for a small portion and it's better on CPU than I'm thinking (just know that imatrix is painfully slower on bf16 lol)

I've had lots of problems with weird overflows and slowdowns and only just got it working tonight properly:

• The BF16 tensors are everything but the experts and on two A6000 GPUs.
• The experts are Q6_K for the down_proj and Q5_K for up_proj and gate_proj and in RAM.

The BF16 PR for llama.cpp was merged a few weeks ago and seems to work fine. It can't use F16 for certain tensor(s) or it overflows, and any quant causes some weird slowdowns where the prompt processing takes 2.5x longer and the token generation about 1 tokens/s less (which is a lot when you're only getting 3 tokens/s!).

It's been a long slog getting it all working, but it's nuts how good it is at writing!

No other LLM I've ever tried can come even remotely close to being able to write chapters out of order like this:

USER

Varis adjusted the noose, its hemp fibers grinding beneath his calluses. “Last chance,” he said, voice like gravel dragged through mud. “Confess, and your soul stays your own.”

Jurl laughed—a wet, gurgling sound. “You’re knee-deep in it, Coldwater. ” The thing inside him twisted the boy’s lips into a grin too wide for his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through… ”

Turn this into the opening chapter of a Grimdark trilogy.

ASSISTANT

The gallows creaked like a dying man’s breath. Varis Coldwater stood atop the splintered platform, the noose in his hands as familiar as sin. Below, the town of Blackmoor huddled—a carcass of leaning timber and crumbling stone, its people gaunt shadows gathered in the square. They reeked of desperation, their eyes hollow as the sockets of the skulls nailed above the butcher’s stall. Autumn had stripped the oaks bare, and the wind carried the stench of rot from the moors, where the peat devoured the unwary.

“Last chance,” Varis growled, the hemp rough against his palms. He’d hanged seven men on this rope. Their faces blurred now, but their screams never did. “Confess, and your soul stays your own.”

Jurl dangled, wrists bound, his boyish frame too slight for the iron chains. Blood crusted his temple where the mob had struck him—before they lost their nerve. Before they saw the black veins spidering beneath his skin.

The thing inside Jurl laughed, a sound like drowned lungs heaving. “You’re knee-deep in it, Coldwater.” The boy’s jaw cracked sideways, teeth splintering as the grin split his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through…”

A woman in the crowd crossed herself. Old Tessa, the midwife. Her lips moved in a silent prayer to saints long forgotten. Varis didn’t believe in prayers. Only the work.

He yanked the lever.

The trapdoor crashed open—

—and Jurl twisted.

The boy’s body snapped taut mid-fall, suspended by nothing. Chains exploded, shrapnel shredding the air. A farmer screamed as a link buried itself in his thigh. The crowd scattered, but Varis stood frozen, watching as Jurl’s spine arched, ribs punching through flesh like antlers. The thing wearing his skin howled, a chorus of voices that scratched at the sky.

“YOU SHOULD HAVE LISTENED, HANGMAN.”

The earth shuddered. Graves in the churchyard split, skeletal hands clawing free. The air curdled, and the horizon rippled—a massive gate of tarnished iron materializing in the distance, its hinges weeping rust. Beyond it, shadows writhed. Hungry. Familiar.

Varis’s hand flew to the amulet beneath his shirt—a wolf’s fang, warm as a heartbeat. Mari’s fang. The last relic of the order that had burned with her.

“The Gate…” Old Tessa whispered, collapsing to her knees. “*Gods save us, it’s open.*”

Jurl’s corpse hit the ground, deflated. But the gate remained. And the shadows swarmed.

Varis was running before he’d decided to move, snatching his axe from the execution block. A child’s wail cut through the chaos—a girl trapped beneath a cart, her mother’s body splayed beside her. He lunged, hauling the cart aside, but the shadows were faster. They coiled around the girl, viscous as tar, and her scream dissolved into a wet gurgle.

“Bastards!” he roared, swinging the axe. The blade passed through the darkness harmlessly.

Mari’s voice, sharp in his memory: “Steel won’t bite the dead, you fool. Only blood. Only sacrifice.”

The amulet burned.

He fled, the gate’s howl chasing him into the moors. Behind, Blackmoor burned, its people reduced to puppets jerking on shadow-strings. He didn’t look back.

Coward, the wind hissed. Cripple.

His leg—the old injury from the siege at Veldmark—throbbed. But he ran, the fang’s heat searing his chest.

The Great Wolf was coming. And Varis Coldwater, last of the Grey Order, would need to remember how to bite.

End of Chapter One

Hook: The chapter closes with Varis escaping into the moors, the amulet (a relic tied to the Great Wolf) guiding him toward a forgotten shrine. His internal conflict—guilt over past failures vs. the ruthless pragmatism needed to survive—sets the tone. The Dead’s Gate’s opening unleashes minor horrors here, but hints at greater threats (the Wolf, political rot in the realm). The next chapter could introduce a survivor from the town (Old Tessa?) or a rival hunter sent to silence him, escalating tension.

USER

Can you now write the prologue of the book which should come before this chapter. It should be a slower pace and foreshadow something much further into the world's history than happened in chapter 1.

ASSISTANT

Long before Blackmoor’s gallows cast their shadows, before the Grey Order’s sigils faded to ash, there was the Wolf—and the Gate.

The air reeked of burnt thyme and blood.

Elynna of the First Keep knelt in the snow, her hands raw from digging. The earth here was unyielding, even to a queen. Frost gnawed through her furs, but she did not shiver. Fear had hollowed her into something colder. Around her, the remnants of the Nine Clans waited, their banners limp in the windless dark. The Wolf’s Maw Pass loomed above, jagged as broken teeth, and beyond it… the Veil.

“It’s not enough,” whispered Kethran, her Shield-Captain. His sword lay abandoned in the snow, its edge notched from cleaving things that bled black. “The pact demands more.”

Elynna did not look at him. She cradled the child instead—a boy, swaddled in wool dyed with juniper and woad. His mother had named him Haelyn. A good name. A sacred name. Now it was a curse.

“The Wolf took his due already,” she said. Her voice sounded distant, even to herself. “The villages. The southern host. My son.”

“Not his hunger,” Kethran said.

The Veil rippled.

It hung in the air like rotten lace, a scar torn across the pass. Through its threads, Elynna glimpsed the Otherroot Forest—trees bent into screams, rivers thick with ash. The Dead’s Gate was not yet forged, but its architects clawed at the edges of the world. She could hear them. Whispering.

“The iron,” she ordered.

They brought it raw from the mountain’s heart, molten and shrieking. The smiths, those who still lived, channeled the seething metal into grooves Elynna had carved. Glyphs older than language. Older than gods. The snow hissed where the iron touched it, bleeding steam into the night.

When the last sigil cooled, she placed the child atop the central rune.

“Forgive me,” she murmured—not to the babe, but to the shadow pooling beneath the stars. To the Wolf, who was not a god but a debtor.

The ritual began.

They sang no hymns. The Clans knew better than to court the attention of greater hungers. Instead, they slit their palms and let their blood freeze on the stones. Elynna pressed her dagger to the child’s throat. A single drop fell, smoking where it struck the iron.

The Veil screamed.

For three breaths, the world hung suspended. Then, with a sound like a thousand bones snapping, the Dead’s Gate erupted from the earth—iron ribs, a arch of tarnished teeth, its surface etched with the same glyphs that now glowed scarlet beneath the child. The Veil frayed, stitches dissolving, as the Gate sealed itself shut.

The Clans roared. Kethran wept.

But Elynna stared at the child’s body. No breath fogged the air above his lips. His eyes, though—

His eyes were open.

Black as the space between stars.

“We paid,” Kethran breathed, gripping her shoulder. “The Wolf accepted the pact. The Gate is sealed.”

Elynna said nothing. She wrapped the boy in her cloak, fingers lingering on the single milk tooth in his tiny fist. A tooth she had not placed there.

When the Clans retreated, drunk on victory, she remained. The mountain’s whispers followed her:

“A crown of iron cannot halt decay…
The Wolf’s debt is paid…
…but rust remembers.”

By dawn, the snow had buried the glyphs. By winter’s end, Elynna’s hair turned white. And when the first ravens brought word of black veins spreading in the north—of crops that sprouted teeth, of babes born with hollow eyes—she smiled.

For she knew the truth:

All gates open both ways.

End of Prologue

Foreshadowing & Themes:

• The Wolf’s Pact: The ritual’s “success” established a cycle—the Gate can only be sealed through sacrificial bargains with the Wolf, a primordial force that demands escalating cruelty. This ties to Varis’s amulet (crafted from a relic of these events) and the Dead’s Gate’s resurgence in Chapter One.
• The Child’s Eyes: The hollow-eyed boy foreshadows Jurl’s possession and the novel’s exploration of “vessels” for ancient evils.
• Rust as a Motif: The prologue’s closing lines (“rust remembers”) hint at the Gate’s inevitable return, mirroring Chapter One’s “rusted through” imagery.
• Moral Decay: Elynna’s grim acceptance of collateral damage (“babes born with hollow eyes”) mirrors Varis’s moral compromises, grounding the trilogy’s grimdark tone in generational rot.

Pacing: Deliberately slow, steeped in ritual and silence. Contrasts with Chapter One’s chaos, establishing a mythic scale before narrowing to Varis’s personal struggle.

Chapter 3 should introduce somebody from "the other side"

ASSISTANT

The Otherroot Forest did not bleed. It seethed.

Haelyn walked the ashen paths, his bare feet leaving no prints. The trees here grew upside-down, roots clawing at a sky the color of a bruise, their branches buried deep in the soil. Things moved in the canopy—shapes with too many joints, their eyes flickering like dying stars. They watched him. They always watched.

He hummed as he walked, a lullaby the Clans had sung centuries ago. The melody unraveled in the air, notes curdling. Behind him, the forest bent. Roots uncoiled to let him pass; brambles withered to dust. The Wolf’s scent clung to him—smoke and frostbite—a reminder of the pact that had carved him into a key.

“Little hollow king,” the trees crooned. “Open us. Open us again.”

Haelyn smiled, his teeth sharp as a child’s milk teeth. “Patience.”

He paused at the edge of the Rotmere, a lake of stagnant ink where the Veil thinned. The water showed reflections of the mortal realm—flickers of fire, screams muffled as if through glass. He crouched, trailing fingers through the sludge. Images surged: a man with a wolf’s fang amulet fleeing through moors; a gate weeping rust; shadows feasting on a girl’s bones.

“Ah,” Haelyn breathed. “There you are.”

The Rotmere’s surface hardened, capturing the vision—Varis Coldwater, limping toward the horizon, the amulet glowing faintly against his chest. Haelyn tilted his head. The last Grey Order hunter. How… pedestrian. And yet, the Wolf’s fang had chosen him. Or perhaps it was the other way around.

A rasping chuckle echoed behind Haelyn. “Sentiment, brother?”

He didn’t turn. He knew the voice—a thing wearing the skin of a long-dead smith, its jaw unhinged to accommodate a nest of centipedes. The Rotguard. Keepers of the Gate’s backdoor.

“Sentiment is a mortal sickness,” Haelyn said lightly. “I’m merely curious. The Wolf’s leash tightens, and this one… resists.”

The Rotguard oozed closer, centipedes spilling from its sleeves. “The Dead’s Gate is open. Let the feast begin. Why delay?”

Haelyn stood, wiping his hand on his tunic—a habit left from when he’d still believed filth could cling to him. “Because gates swing both ways, dear keeper. The mortals think they fear what lies here. They don’t yet realize… we fear what they are becoming.”

The vision in the Rotmere shifted: Varis now stood before a crumbling shrine, its stones etched with the same glyphs from the prologue’s ritual. The amulet blazed in his grip, and for a heartbeat, Haelyn saw her—Elynna of the First Keep, her ghost chained to the fang, screaming soundlessly.

Ah. So that’s how you survived, witch.

The Rotguard hissed. “The Grey Order’s remnants are nothing. Crush him. Take the key.”

Haelyn’s black eyes narrowed. “You mistake me for a servant. The Wolf’s debt is mine to collect.”

With a flick of his wrist, the Rotmere’s surface shattered. The Rotguard staggered back, centipedes shriveling as Haelyn’s will lashed out. The forest stilled, the air thick with submission.

“The Gate isn’t just a door,” Haelyn murmured, more to himself than the cringing keeper. “It’s a mirror. And mortals… they’re so very good at breeding monsters.”

He turned north, where the Dead’s Gate’s shadow pulsed on the horizon. The closer he walked, the more his body warped—skin translucent, veins blooming like black ivy. The Gate’s rust sang to him, a chorus of decay.

Come home, it whispered.

But Haelyn wasn’t ready. Not yet.

Instead, he knelt and pressed his palm to the ground. The soil split, vomiting forth a thing that might have once been a stag—antlers fused into a crown of thorns, ribs pierced through its sides like spears. It groaned, milky eyes rolling toward him.

“Find the hunter,” Haelyn commanded. “Lead him here. To the edge.”

The stag shuddered, blood like tar bubbling from its nostrils. But it obeyed.

As it loped into the gloom, Haelyn dissolved into smoke, his laughter trailing behind.

End of Chapter Three

Purpose & Connections:

• Haelyn’s Role: A manipulative force from the “other side,” he’s both antagonist and reluctant ally. His connection to Elynna (implied to be his mother) and the Wolf’s pact adds tragic depth.
• The Rotmere: A dark mirror to mortal realms, allowing Haelyn to spy on Varis. Establishes that the Gate’s opening affects both worlds.
• Themes: Explores cycles of sacrifice (Haelyn = the child from the prologue) and the blurred line between monster and man.
• Foreshadowing: The stag’s corruption hints at environmental decay in Varis’s world. Haelyn’s fear of “what mortals are becoming” suggests a looming twist—the true threat isn’t the Otherroot, but humanity’s own descent.

Grimdark Elements:

• Body horror (Rotguard’s centipedes, mutated stag).
• Moral ambiguity (Haelyn’s motives are self-serving but layered).
• Existential dread (the Gate as a “mirror” reflecting humanity’s rot).

Next Steps: Chapter 4 could intercut Varis’s encounter with the mutated stag (testing his resolve) and Haelyn’s machinations, building toward their inevitable collision.

Chapter 2 - you decide!

ASSISTANT

The moors were alive with whispers.

Varis Coldwater stumbled through the fog, his breath ragged. The amulet—Mari’s fang—burned against his chest like a brand. Behind him, Blackmoor’s pyre smudged the horizon, a greasy smear of smoke. The Dead’s Gate’s howl had faded, but the air still thrummed with its echo. He could feel it in his teeth.

His leg screamed. The old wound from Veldmark had split open during his flight, blood seeping through the bandages he’d torn from his cloak. Pathetic, he thought. The Grey Order’s last hunter, limping toward a ghost.

Mari’s ghost.

The shrine lay somewhere in these moors, its location half-remembered from her drunken ramblings. “Pray there if you ever tire of living,” she’d once sneered, her breath reeking of juniper gin. “The Old Wolf answers—but he chews his blessings raw.”

A guttural cry split the fog. Varis froze, axe raised. The sound came again—not human. Not animal. Something wet.

He found the source in a peat hollow. A sheep, or what remained of one. Its wool sloughed off in clumps, revealing muscle threaded with black veins. The creature’s skull had ruptured, antlers of jagged bone jutting from its eye sockets. It gnawed on its own hind leg, jaws snapping with mechanical hunger.

Rot.

The Dead’s Gate’s breath.

Varis edged backward, but the thing stiffened, nostrils flaring. Its head swiveled toward him, antlers trembling.

“Easy,” he muttered, though the word felt foolish. This was no beast to soothe.

It lunged.

Varis sidestepped, axe biting into its neck. The blade sank deep, but the thing didn’t slow. It whipped around, antlers gouging his thigh. He fell, peat slurry filling his mouth. The creature loomed, jaws unhinging—

—and exploded.

A spear of bone-white wood punched through its chest. The sheep-thing spasmed, black blood sizzling as it slid down the shaft. Behind it stood a woman, her face obscured by a hooded cloak stitched with crow feathers. She planted a boot on the carcass and yanked her spear free.

“That’s a Grey Order axe,” she said, voice like rusted hinges. “But you’re no brother of theirs. They died squealing.”

Varis spat peat. “Mostly.”

The woman lowered her hood. Old Tessa, the midwife from Blackmoor—but her eyes were wrong. One remained milky with cataracts; the other glowed faintly, the pupil slit like a cat’s.

“You,” he rasped.

“Me.” She tossed him a waterskin. The liquid inside reeked of rotgut and wormwood. “Drink. The fog here’s thick with the Gate’s piss. It’ll hollow your lungs if you let it.”

He drank. Fire seared his throat. “Why follow me?”

“Didn’t.” She crouched, prying a blackened molar from the sheep’s jaw. “Followed them. The Rot’s spreading faster than a pox in a brothel. Crops, livestock, babes…” She pocketed the tooth. “You’re heading to the shrine.”

It wasn’t a question.

Varis stood, testing his leg. “What’s left of it.”

Tessa’s slit pupil narrowed. “It’s still there. The Rot can’t touch stone that old. But the path’s… changed.” She gestured to the fog. “Things walk it now. Things that remember.”

He didn’t ask how she knew. The crow cloak, the altered eye—she’d bargained with something. Everyone did, out here.

They walked.

The moors shifted. Tussocks of grass became knuckles of exposed bone. Lichen glowed faintly, chartreuse veins pulsing in time with the amulet’s heat. Twice, shapes flitted at the edge of vision—tall, jointless, their heads tilted too far to one side. Tessa drove them off with a flick of her spear, muttering in a tongue that made Varis’s gums ache.

At dusk, they found the shrine.

It was little more than a cairn of lichen-crusted stones, half-sunk in a bog. But the carvings remained—wolves with human eyes, gates festooned with chains, and a woman with a dagger raised above a child. Elynna’s Pact.

Varis traced the glyphs. “You knew I’d come here.”

Tessa lit a pitch-soaked torch. “Knew you’d need to. The fang didn’t choose you for your charm.”

He gripped the amulet. “And you? What chose you?”

Her slit eye flickered. “Same thing that chose the boy, Jurl. The Rot’s just a symptom, Coldwater. The sickness is older. It’s in the blood.”

Before he could demand answers, the torchlight caught something in the cairn’s heart—a recess lined with teeth. Human, animal, others too sharp to name. At its center lay a dagger. Bronze, its hilt wrapped in wolfskin.

Mari’s voice, unbidden: “Blood for the key. Blood for the lock.”

Tessa inhaled sharply. “Walk away. Now.”

But Varis was already reaching.

The moment his fingers brushed the dagger, the cairn shuddered. Stones groaned, grinding into a new configuration—an archway, choked with roots. Beyond it stretched a road paved with rib bones, vanishing into a horizon choked with stormclouds.

And on that road, something moved.

A stag, its antlers a nest of thorns, eyes leaking smoke. It paused, nostrils flaring, before lowering its head in a mockery of reverence.

Toward Varis.

Toward the amulet.

“No,” Tessa breathed. “Not here. Not now.”

The stag charged.

Varis raised the dagger. The world dissolved into screams—his, the stag’s, and a third voice, ancient and hungry, that lived in the marrow of the stones.

When the silence returned, the archway was gone. The cairn lay scattered, the dagger clutched in Varis’s fist. His arm burned, black veins creeping from his palm to his elbow.

Tessa stared at him, her face ashen. “Fool. You’ve opened a door that can’t be shut.”

He didn’t answer. The vision lingered—a figure on the bone-road, slender and pale, watching him with eyes like voids.

Waiting.

End of Chapter Two

Connections & Foreshadowing:

• Tessa’s Bargain: Her altered eye and knowledge hint at alliances with unseen forces, setting up her role as a reluctant guide/antagonist.
• The Dagger: A cursed relic linking Varis directly to Elynna’s Pact (prologue) and Haelyn’s realm (Chapter 3). The black veins mirror Jurl’s corruption.
• The Stag: Haelyn’s mutated servant (from Chapter 3) makes its first appearance, tying Varis’s journey to the Otherroot’s machinations.
• Bloodline Sickness: Tessa’s line about sickness in the blood foreshadows revelations about Varis’s lineage and the Grey Order’s true purpose.

Grimdark Beats:

• Body horror (mutated sheep, black veins).
• Moral decay (Tessa’s ambiguous allegiance, Varis’s cursed dagger).
• Existential dread (the bone-road, the figure watching).

Next Chapter: Chapter 3’s Haelyn POV gains context—the stag’s failure, Varis’s cursed arm, and the opening of a “door” that escalates the Rot’s spread.

Chapter 4: make it all link

ASSISTANT

The Rot had a voice.

It lived in Varis’s arm now, the black veins coiling up to his shoulder, whispering in a language that made his molars ache. Sacrifice, they hissed. Open. Feed. Beside him, Tessa muttered curses as they trudged through the skeletal remains of the Wolfpine Woods. The trees here were petrified, branches twisted into agonized silhouettes against a clotting sky.

“You’re slowing,” Tessa said, her crow-cloak fluttering like a wound.

“And you’re lying,” Varis shot back. The dagger—Elynna’s dagger, he realized—hung heavy at his belt. “You knew that shrine would mark me.”

She didn’t deny it.

Ahead, the woods gave way to a valley choked with mist. At its center loomed a jagged spire—the First Keep, its stones blackened by ancient fire. The Grey Order’s birthplace. Mari’s grave.

“Blood for the key,” the Rot sang in his arm.

Tessa halted. “They’re here.”

The mist parted.

Shadows congealed into figures—twelve of them, their armor fused to flesh, helms rusted shut. The Grey Order’s last knights. Or what remained after the Dead’s Gate’s first opening. They stank of embalming spices and wet soil.

“Mari’s whelp,” the lead knight rasped, sword blooming with orange lichen. “The Wolf wants his due.”

Varis drew his axe. “He can choke on it.”

The knights attacked.

It was not a fight. It was a slaughter—but not theirs.

Varis moved like a man already dead. The Rot guided him, sharpening his reflexes, numbing the pain as blades bit into his ribs, his thigh, his collarbone. He shattered a knight’s helm, revealing Mari’s face beneath, her eyes sewn shut with sinew.

“Liar,” she gurgled, though her corpse had no tongue.

He faltered.

A sword punched through his gut.

Tessa’s spear took the knight’s head, but the damage was done. Varis collapsed, blood pooling beneath him. The knights closed in, a noose of rust and rot.

“Pathetic,” Tessa spat. “She died for this?”

The Rot laughed. Open. Feed.

Varis gripped the dagger.

And plunged it into his own chest.

The Otherroot Forest

Haelyn felt the sting in his ribs—a phantom pain, sharp and sweet. He smiled.

“Finally,” he breathed.

The Rotmere’s surface trembled as Varis’s blood seeped into the First Keep’s stones, as the amulet—Mari’s fang—flared with stolen light. Haelyn stepped into the lake, ink swallowing him whole.

It was time to collect.

The First Keep

Varis awoke choking on blood. And laughter.

The knights were gone. The mist too. Moonlight speared through the Keep’s shattered roof, illuminating the figure crouched beside him. Pale. Slender. Eyes like starless voids.

“Hello, nephew,” Haelyn said.

Varis tried to rise, but the dagger pinned him to the ground—no, not a dagger. A fang. The amulet was gone, fused to his sternum.

“You—”

“—look like her. Elynna.” Haelyn tilted his head, black curls falling into his face. “She wept when she buried me. Did you know? All that power, wasted on guilt.”

Tessa lay nearby, her crow-cloak torn, slit eye gouged out. Breathing, but barely.

“Why?” Varis growled.

Haelyn pressed a frostbitten finger to the fang amulet. “The Wolf’s pact was never about sealing the Gate. It was about balance. A life for a life. A world for a world.” His grin widened. “Elynna gave them me. But you… you’ll give them everything.”

The floor split. Roots erupted, dragging Varis down into the earth. He screamed, but the sound dissolved into the Rot’s chorus—

Ephemera

—He sees the Grey Order’s true purpose: not hunters, but jailers. Mari, young and unbroken, standing beside Elynna’s heir at the Dead’s Gate. Their betrayal. The Wolf’s wrath.

—Haelyn as a child, not sacrificed but offered, his hollow eyes reflecting the Gate’s first scream.

—Tessa, decades younger, cutting a deal with a shadow in exchange for her eye. For a chance to bury the fang where only a desperate man would find it.

The First Keep

Varis woke a second time. Dawn bled through the ruins. His wounds had healed, the Rot’s veins now mapping his entire torso. Haelyn was gone.

But the Gate’s howl was louder.

Closer.

Tessa stirred, her remaining eye milky. “What… did you do?”

Varis stood. The amulet pulsed, Mari’s voice now a dirge in his skull. Beneath the Keep, something stirred.

“What you made me do,” he said.

He walked north, toward the howling.

Behind him, Tessa whispered the truth they’d both denied:

“Elynna’s blood runs in your veins. The Gate doesn’t want you dead, Coldwater. It wants you king.”

End of Chapter Four

Links & Payoffs:

1. Bloodline: Reveals Varis as Elynna’s descendant, explaining the amulet’s bond and his forced role in the cycle.
2. Haelyn’s Motive: Positions him as a bitter “uncle” manipulating Varis to usurp the Wolf’s pact.
3. Tessa’s Betrayal: Her deal with the Rot (foreshadowed in Ch. 2) ties to her orchestrating Varis’s path to the shrine.
4. The Rot’s Voice: Now symbiotically tied to Varis’s fate, merging his arc with the Gate’s sentient decay.
5. Mari’s Ghost: Her haunting of Varis (Ch. 1-2) mirrors Elynna’s guilt, binding past sins to present choices.

Grimdark Crescendo:

• Varis’s forced “ascension” as a reluctant heir to the Gate’s throne.
• Haelyn’s manipulation reframes the Dead’s Gate as a generational trap.
• The cycle of sacrifice continues, now with Varis as both pawn and patriarch.

Next Move: Chapter 5 can escalate the Rot’s physical manifestations (corpse armies, sentient storms) while forcing Varis to confront Haelyn directly—not as enemies, but as mirrors of each other’s cursed legacy.

Chapter 5: Wur doomed

ASSISTANT

The Dead’s Gate didn’t just howl now—it sang.

Varis walked the ashen plains, his boots crunching through fields of brittle bone. The Rot had reached his throat, black veins branching across his jaw like cracks in pottery. Every breath tasted of iron and loam. Every heartbeat rattled the fang amulet fused to his chest, its pulse synced to the Gate’s distant, grinding shriek.

Tessa trailed ten paces behind, half-blind and hobbling. She’d stopped speaking three days ago, after the Rot ate her tongue.

Deserved, Varis thought.

The sky hung low, a sagging membrane streaked with luminous rot. Below it, the land buckled. Rivers ran backward. Trees split open to vomit faceless, mewling things. The Wolf’s shadow loomed everywhere, a stain at the edge of vision.

“Wur doomed,” the Rot whispered with Tessa’s stolen voice. “Wur doomed, wur doomed—”

“Quiet,” Varis snarled.

But the Rot was right.

The Rotmere

Haelyn waded through the lake of ink, his reflection splintering into a thousand screaming faces. The Veil between worlds hung in tatters, and through the gaps, he watched Varis’s pilgrimage—a squirming, glorious inevitability.

The stag awaited him on the shore, its antlers now fused with jagged iron.

“Is it time?” it gurgled, bile pooling between its hooves.

Haelyn stroked its distended neck. “Almost. My nephew needs one last push.”

He raised a hand, and the Rotmere convulsed. Images surged:

—A village, its wells choked with hair and teeth.
—A knight of the Grey Order, his armor sprouting fungal blooms, leading a procession of hollow-eyed children toward the Gate.
—Tessa, in her final moments of clarity, carving a rune into her thigh—a rune that matched the one on Varis’s dagger.

Haelyn clenched his fist. The visions shattered.

“Go,” he told the stag. “Make him see.”

The Plains of Teeth

They found the village at dusk.

Or what the Rot had dressed as a village. The huts were cobbled from fused rib cages, the streets paved with knucklebones. Figures shuffled in the gloom—corpses wearing the faces of Blackmoor’s dead. Jurl stood at the center, his grin still too wide, black veins now devouring his entire body.

“Coldwater,” Jurl crooned. “C-come to s-sacrifice again?”

Tessa moaned behind her gag.

Varis unslung his axe. “Stay back.”

“Or what?” Jurl’s head lolled. “You’ll f-feed me to your master?”

The ground erupted.

Skeletal hands clawed free, followed by rib cages, skulls, a writhing mass of reanimated rot. Jurl laughed, the sound wet and rupturing, as the corpses surged.

Varis swung the axe, but the Rot guided his strikes—here, a bisected corpse spasming acid; there, a child’s reanimated husk clawing at Tessa. He fought mechanically, the amulet’s heat searing his ribs.

“Pathetic,” Jurl slurred, suddenly inches from Varis’s face. His breath reeked of gangrene. “Y-you could’ve been a king. Now you’re just the Wolf’s d-dog.”

Varis headbutted him.

Jurl collapsed, giggling, as black sludge leaked from his nose. “T-the Gate’s gonna chew this world to pulp. And you—” he coughed, ribs snapping as the Rot within him squirmed, “—you’ll hold its j-jaw open.”

The stag’s cry cut through the chaos.

It thundered into the village, antlers gouging earth and bone. The corpses scattered. The stag skidded to a halt before Varis, smoke pouring from its nostrils.

“Follow,” it hissed.

Varis hesitated.

Tessa lunged, her remaining eye wild. She seized the dagger at his belt—Elynna’s dagger—and plunged it into the stag’s chest.

The creature screamed.

So did the Gate.

The Threshold

The world tore.

Varis stumbled as the plains split, the ground yawning open to reveal the Dead’s Gate below. Not a gate anymore—a maw. Iron teeth dripped rust, the archway stretched into a throat, the shadows beyond it pulsing like a gullet.

Haelyn stood at its edge, arms spread.

“Nephew!” he called, cheerful. “You’re late!”

Tessa lay at his feet, the dagger buried in her stomach, her hands still gripping the hilt. Her remaining eye fixed on Varis, accusing.

“She thought the dagger could kill me,” Haelyn sighed. “But it’s not a weapon. It’s an invitation.”

Varis’s amulet flared. The Rot surged, and suddenly he understood:

The fang wasn’t Mari’s.

It was Haelyn’s.

The child from the prologue’s ritual—his first tooth, offered to seal the Gate. The Rot had kept it. Had kept him.

“All this time,” Varis rasped. “You weren’t trying to open the Gate.”

Haelyn smiled. “I am the Gate.”

He stepped aside.

In the maw’s depths, Varis saw them—the Grey Order, chained to the Wolf’s shadow. Mari stood at the front, her eyes sewn shut, her mouth moving in silent plea.

Join us.

Lead us.

Feed us.

The Rot roared in agreement.

Epilogue: The First Bite

Varis fell to his knees. The amulet split his skin, fang becoming tooth becoming key. The Gate’s maw yawned wider.

Haelyn knelt beside him, cold hands cradling his face. “Shh. It only hurts until you bite.”

Varis screamed.

But when the jaws closed, it was not him they devoured.

It was the world.

End of Chapter Five

Grimdark Payoffs:

• Varis’s Corruption Complete: The Rot and amulet merge, revealing him as the Gate’s intended vessel—Haelyn’s replacement.
• Tessa’s Futile Sacrifice: Her attempt to break the cycle only accelerates it, emphasizing the trilogy’s nihilistic core.
• Haelyn’s True Nature: Not a villain, but a fellow victim of the Wolf’s cycle, desperate to escape his role by passing it to Varis.
• The Gate’s Sentience: The Dead’s Gate is a living entity, its “hunger” a metaphor for humanity’s inevitable self-destruction.

Final Lines’ Dread: The world’s consumption isn’t an end—it’s a transformation. Book Two can explore the aftermath: Varis as a reluctant Devourer-King, Haelyn’s ghost haunting him, and pockets of humanity surviving in the Gate’s belly, evolving into monstrous counterparts to the Otherroot’s horrors.

Title Double Meaning: “Wur doomed” reflects both the villagers’ dialect and the Rot’s twisted mantra, symbolizing inescapable decay—personal and cosmic.

USER

Write me the opening chapter of a Grimdark trilogy in the style of Joe Abercrombie and Rob J Hayes. Use third person personal and feature internal monologues of the characters. The POV character for chapter 1 is a 'Mercer' who's job is to put the mortally wounded out of their mystery after a battle. He has no conscience about what he does. The story starts the morning after the battle and the moor where it took place is blanketed in mist. Something stirs a flashback in the POV character.

ASSISTANT

The moor wept.

Mist clung to the earth like a shroud, swallowing the sun and staining the world the color of ash. Mercer’s boots sank into mud thickened with blood, each step a wet, sucking protest. The battlefield sprawled before him, a graveyard of broken men and shattered steel. Ravens hunched like black-robed priests over their sermons of entrails. They scattered as he passed, wings snapping curses into the damp air.

Another day, another harvest.

He adjusted the weight of his tools—a leather satchel of scalpels, a bone saw, and the squat, heavy cleaver he called Kindness—strapped to his hip. His hands were gloved, always gloved. Not for the blood. For the cold. Or so he told himself. The chill gnawed through the cracked leather anyway, biting fingers that had long forgotten how to tremble.

A low moan slithered through the mist. Mercer turned, following the sound to its source: a boy, no older than sixteen, sprawled in a puddle of his own innards. His breastplate bore the sigil of House Veyne—a stag pierced by arrows. The kind of emblem nobles paid extra to have etched, as if beauty might turn blades. It hadn’t.

“Please…” The boy’s voice was a wet rasp, pupils blown wide with pain. “M’mother… she’s in Farwatch. Tell her I—”

Mercer knelt, the boy’s blood seeping into his trousers. They always beg for messages. As if words could stitch them back together. He unsheathed the cleaver. “She’ll hear you died bravely,” he lied. The words tasted stale.

The boy’s lips parted—to thank him, maybe, or pray. Kindness fell before he could decide. The blade crunched through bone, swift and precise. A clean kill. A professional kill. The head rolled, jaw slack, eyes frozen in that wide, grateful look they all wore at the end. Like lambs.

Mercer wiped the cleaver on the boy’s tabard and stood. No shudder. No bile. Just the familiar hollow grind in his chest, like a rusted gear turning. This is what you are, it whispered. A shepherd for the damned.

He moved on.

The mist thickened, curling around his ankles as he picked through the carnage. Here, a knight with his legs sheared off, whimpering as he clawed at the dirt. There, a mercenary choking on a lungful of blood, fingers knotted in the rosary of some dead god. One by one, Mercer ended them. A slit throat. A punctured heart. No flourish. No cruelty. Just business.

Until the locket.

It glinted in the hand of a dead woman—a sellsword, her face split by an axe. The chain pooled in her palm like liquid silver, the pendant cracked open to reveal a tiny portrait: a girl, no older than five, with wheat-blond hair and a gap-toothed smile.

Mercer froze.

—firelight on a doll’s porcelain face, laughter like bells, small hands pressing a crudely carved horse into his—“

No.

He crushed the memory like a ember in his fist. His gloves creaked as he pried the locket free, tucking it into his satchel. The dead didn’t need trinkets. The living did. Especially those who traded in secrets.

“Mercer.”

The voice came from behind him—a growl steeped in smoke and rot. Captain Hark, his face a slab of scarred meat beneath a rusted helm. The man’s left arm hung in a sling, the stink of infection already wafting from the bandages.

“You missed one,” Hark spat, jerking his chin toward a figure crumpled against a lichen-stained rock. A man in splintered plate, breath rattling like pebbles in a tin. The sigil on his shield—a leering wolf—marked him as Northreach. Enemy. Or what passed for one these days.

Mercer tilted his head. “Your men don’t pay me to cull their own.”

Hark’s laugh was a dagger dragged over stone. “That one’s not mine. Found him crawling toward the treeline before dawn. Didn’t get far.” The captain leaned in, yellowed teeth bared. “He’s got a message for you.”

A flicker in Mercer’s gut. Not fear. Curiosity. “And?”

“Says he knows you. Says you’ll want to hear what’s coming.” Hark’s grin widened. “*Before it hears you.*”

The gear in Mercer’s chest stuttered. Childish theatrics. But his fingers tightened on Kindness all the same.

The Northreach man stirred as Mercer approached, his visor lifted to reveal a face gaunt and pallid, cheeks streaked with old burns. Recognition flared—a ghost from another life.

“Emeric?” The name slipped out, brittle as dead leaves.

The man’s lips peeled back in a grimace. “Still… playing gravedigger, brother?”

The moor vanished.

—smoke, screams, the hiss of rain on burning thatch. Emeric’s laughter as he pressed the torch to the barn, their father’s face contorted in the flames—“

Mercer’s cleaver was at Emeric’s throat before he’d fully drawn breath. “You died at Redreef.”

“Died?” Emeric coughed, blood flecking his chin. “No. They took me. Gave me… gifts.” His trembling hand clawed at his breastplate, tearing it aside to reveal a wound beneath—a jagged hole where his heart should’ve been. Black veins spidered from the edges, pulsing faintly, alive.

“They’re coming, brother,” Emeric hissed. “The Forgotten. The ones who… whisper.” His eyes rolled back, showing milky whites. “You’ll see. When the mist parts… you’ll see.”

The cleaver fell.

Emeric’s head thudded to the ground, but the body… the body twitched. Fingers spasming. Lips still moving, mouthing words without sound. Mercer stared. He’d seen corpses spasm. Seen muscles cling to last sparks of life.

But not like this.

Not with the mist coiling around the severed neck, tendrils probing the wound as if searching for something lost.

A raven shrieked. Mercer stepped back, the hollow in his chest now a yawning pit.

Run, whispered the gear. Run and never look back.

He turned.

And froze.

The mist was… churning. Not with wind. With shapes. Tall, slender, their outlines bleeding into the fog like ink in water. Watching. Waiting.

*—shadows in the smoke, eyes like cracked glass, a voice that was not a voice: ”You belong to us now—”

Mercer blinked. The shapes vanished.

But the mist lingered.

And the moor, he realized, had gone silent.

Author's Note: This chapter establishes Mercer's detachment and introduces the haunting, supernatural undercurrents typical of Grimdark. The flashback triggered by the locket (and later Emeric) hints at a buried past, while the eerie mist and twitching corpse foreshadow the trilogy's larger conflict with the "Forgotten"—an ancient, malevolent force stirring beyond the veil.

Chapter 5 - meta payoff. It all comes together.

Nice work.

Does your MLA version keep the context memory footprint smaller (like the ik_llama fork) of does it balloon like mainline llama does?

It's fairydreaming who added it to llama and then someone else forked it to ik_llama:

https://github.com/ggml-org/llama.cpp/pull/11446

I think ik_llama has merged the MLA branch so it should be the same and only uses a couple of GB for 32k context.

It does seem to trade this for extra compute though and you lose a couple of tokens per second.

I think all the problems I've had may be from a flag fairydreaming added to transpose one of the tensors for a small gain on his CPU system, but it seems that the CUDA backend has a lot of tests that ship off the operations to different functions depending on the shape and float type.

@jukofyork , are you using deterministic samplers or something else? Other than your user request, is your prompt otherwise empty?

@jukofyork , are you using deterministic samplers or something else? Other than your user request, is your prompt otherwise empty?

I'm using Deepseek's own suggested parameters which somebody posted on Reddit a week or so ago:

• No system message (I tend to not use one anyway)
• Temperature of 0.6 (--temp 0.6 )
• All other samplers disabled (--min-p 0.0 --top-p 1.0 --top-k 0 )

I suspect that there are probably lots of buggy instances of this being served. When it wasn't working properly, it has the feeling of being "slightly off" as though it was reading the previous text in some kind of corrupted/distorted way (likely due to the RoPE encoding being mangled and/or some other numerical error). For example:

The gallows creaked like a dying man’s breath. Varis Coldwater stood atop the splintered platform, the noose in his hands as familiar as sin. Below, the town of Blackmoor huddled—a carcass of leaning timber and crumbling stone, its people gaunt shadows gathered in the square. They reeked of desperation, their eyes hollow as the sockets of the skulls nailed above the butcher’s stall. Autumn had stripped the oaks bare, and the wind carried the stench of rot from the moors, where the peat devoured the unwary.

“Last chance,” Varis growled, the hemp rough against his palms. He’d hanged seven men on this rope. Their faces blurred now, but their screams never did. “Confess, and your soul stays your own.”

Jurl dangled, wrists bound, his boyish frame too slight for the iron chains. Blood crusted his temple where the mob had struck him—before they lost their nerve. Before they saw the black veins spidering beneath his skin.

The thing inside Jurl laughed, a sound like drowned lungs heaving. “You’re knee-deep in it, Coldwater.” The boy’s jaw cracked sideways, teeth splintering as the grin split his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through…”

You can see here it's used all the given dialogue and in the correct order. Before it would use some of the dialogue in a "Chinese Whispers" sort of way: not the actual phrases and often not in the correct order (ie: mention something about "knees" later on).

Now it's working properly, it's razor sharp about things like this.

My second attempt to buy a M2 Ultra looks to be yet another retarded "delayed dispatch" scam attempt - sigh.

I have a feeling it could even be the very same person as last time who delayed for a week then tried to say they were "unexpectedly working in Africa" until the end of February... :/

If anybody is interested in running this then you can probably pick up an old "HP Z8 G4" or "DELL T7920" quite cheaply off eBay. Just make sure to get one with Cascade Lake CPUs (ie: with a "2" as the second digit) and populate all 24 dimms with 32GB 2933Mhz DDR4.

It will have around 2x the memory bandwidth of my old E5-2699v4 and paired with a 24GB GPU it should work well (ie: keeping only the essential 32MB attn_k_b unquantised until the overflow problem is found/fixed).

I suspect this will get almost the same as people running purely from CPU with higher RAM bandwidth, as the actual MLA calculations seem to make token generation much more compute-bound than normal (obviously higher RAM bandwidth AND a 24/48GB GPU will beat this, but will also cost 10x more for perhaps 1.5-2x the performance).

Thanks, yeah. My biggest challenge I have right now is it gets stuck on a pattern. So if chapter one had someone slap a table in paragraph one and someone leave the room in anger in the last paragraph, then chapter two will have someone bang their knee in paragraph one and someone leave to the bathroom in the last paragraph, chapter three will be some other similar event .. bump a shoulder and head to the gym and so on and so on

Try adding some extra semi-random text at the end of your prompts.

Here is an example of a buggy float16 version I was testing that hallucinated this Korean character at the start and it completely changes things:

USER

Varis adjusted the noose, its hemp fibers grinding beneath his calluses. “Last chance,” he said, voice like gravel dragged through mud. “Confess, and your soul stays your own.”

Jurl laughed—a wet, gurgling sound. “You’re knee-deep in it, Coldwater. ” The thing inside him twisted the boy’s lips into a grin too wide for his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through… ”

Turn this into the opening chapter of a Grimdark trilogy.

ASSISTANT

韓國

It seems like you're working on a creative writing project that blends dark fantasy and noir elements. Let me help you connect these elements while addressing the "Korean" reference at the end. Here's a streamlined version of your concept with a Korean twist:

Synergy of Elements:
The gritty atmosphere of "Varis adjusting the noose" and Jurl's unnerving laughter could merge with Korean mythos. Imagine Varis as a disillusioned exorcist (gut shaman) in modern Seoul, hunting a parasitic gumiho (nine-tailed fox spirit) that possesses people like Jurl. The "thing inside him" could tie into Korean folklore, such as:

• A gwisin (vengeful spirit) bound to Varis, demanding justice.
• A dokkaebi (mischievous goblin) offering cursed deals.

Korean Influence:
Instead of a generic "confess your sins," the story could explore han (Korean collective sorrow) and the duality of modernity/tradition. The "hemp fibers" and "gravel voice" evoke visceral texture, while phrases like "knee-deep in it" could nod to Seoul’s flooded Cheonggyecheon River, haunted by urban legends.

Revised Snippet with Korean Lore:
Varis tightened the noose, its minari fibers scraping his palms—a remedy no shaman had taught him. The boy’s body arched. “Last chance,” Varis growled. “Confess, and I won’t bury you where the gwisin wail.”
*Jurl’s laughter bubbled like a clogged drain. “You smell of grave moss, Coldwater. Still chasing your sister’s ghost

I think I know why people are getting such varied results with deepseek-r1:

It uses YaRN context extension and as a result it seems to work very differently depending on the max context length you set.

It doesn't help that the openrouter providers have all decided "the bigger the context length the better".

It's particularly shit with 128k or 160k context, and somewhere between 4k and 32k seems best for creative writing.

It's particularly shit with 128k or 160k context, and somewhere between 4k and 32k seems best for creative writing.

Interesting! This is on the back end correct? It doesn't matter if I set my front end to limit context to 32k if the back-end provider spun it up at 128k?

Ah so that's why. I figured the providers like "Kluster AI" must be running the 1.58bit (because it does the thing where it doesn't follow it's thinking in the final response) lol.

This is on the back end correct? It doesn't matter if I set my front end to limit context to 32k if the back-end provider spun it up at 128k?

Correct, the yarn scaling is setup when the model is loaded. Sounds like that "attention dilution" issue Qwen2.5 has at >16k context (and there's an unsloth version which works at >16k but not so well at <16k)

I'm pretty ignorant on the subject, but I see all the distillations of R1 and I am curious. Is it feasible, and would there be any potential benefits to a distillation into something more robust, like Largestral? More creative responses from Largestral but faster inference and I dunno... 90% of DSR1's capabilities?

would there be any potential benefits to a distillation into something more robust, like Largestral?

I'm no expert either, but I did spend a lot of time trying last month. I created a dataset using R1 then SFT-trained
(this is what people call "distilling" now since Deepseek used that term, though proper distilling involves training on logits)

Your intuition about the capability of the base model is spot on btw. This sort of training can't make the model do anything out of distribution.

What worked pretty well for me::

• Largestral-2411, with expanded embeddings to add and tokens + training lm_head

What worked okay:

• Largestral-2411 without changing the tokenizer
• Mistral-Small-24b base model (though it's still a limited / small model)

What failed:

• WizardLM2-8x22b
  (It'd produce nice CoT chains, but then wouldn't follow them in the final response)

• Llama3.3-70b base
  (Probably my bad as I'm less familiar with the hyperparameters for this one)

• Qwen 2.5 72b, Qwen 2.5-32b
  (These models don't seem to have a lot of fiction in the pretraining)

It didn't get to 90% of deepseek IMO, and didn't handle longer context very well. I paused working on this when the Deepseek API got overloaded / I couldn't top-up my credits to generate more data.

I'm hoping Gemma 3 27b base comes out soon with > 8k context, as I think Gemma has really good pre training.

I also tried GPRO-training Mistral-Small-24b on GSM8k, but this didn't carry over to writing at all.
I don't suppose you guys have a good idea for implementing a reward function for creative writing?
All I can come up with is having another model evaluate and rank the story based on criteria, but this would add a LOT of latency to the training pipeline.

P.S. I noticed using the https://github.com/ggerganov/llama.cpp/pull/11446 (MLA) fork + your sed commands to prevent allocating the old KV cach;, after a few messages or messages with code in them, the model breaks down and writes replies like this:

Have you encountered anything like this? I suspect it's because I'm running such a small quant: gghfez/DeepSeek-R1-11446-Q2_K without the Dynamic Quant work Unsloth did.

This actually could just be to do with this:

https://github.com/ggml-org/llama.cpp/pull/11446#issuecomment-2692660730

I think I've got such a huge compute buffer due to offloading the experts to CPU/RAM so it could happen much quicker than 2/3rds of max-context.

Correct, the yarn scaling is setup when the model is loaded. Sounds like that "attention dilution" issue Qwen2.5 has at >16k context (and there's an unsloth version which works at >16k but not so well at <16k)

Yeah, using 4k (the pre-YaRN context length) also makes it dumber, so there must be a sweet spot around 16-64k.

All I can come up with is having another model evaluate and rank the story based on criteria, but this would add a LOT of latency to the training pipeline.

I've given up experimenting until I can find a good method of not just learning the formatting of the stories, but I did plan to try using RL:

• Have a larger/smarter LLM try to work out which continuation of a story was the real one and which was the LLMs generated one (possibly a bit tricky if the larger LLM has been trained on every authors' work already though).
• Either outright ask the larger LLM for a probability or use sampling to get one.
• Calculate r = 2p - 1 (or something similar).
• Use this reward and Temporal Difference Learning to learn control vectors (ie: treating the hidden state(s) as the RL state space and trying to find direction(s) that minimise the regret from the jumps between "good story space" to "crap story space").

The idea being that instead of the current control vectors that just sample a single token after the prompt and then apply this direction all throughout the context, this should (in theory) be able to find directions that push the whole story generation towards better stories, and if the larger model can detect them; avoid the horrible "attractor phrases" like "shivers down spine" or name-slop, etc.

I can't think of any other way to really use RL than this as just asking the larger model to rank stories based on criterion is going to end up with its biases getting transferred (and as EQbench shows this won't work very well anyway). Even humans can't do this reliability: about 30 years ago me and my friend tried to set something up like this to use RL to generate techno from rewriting systems, but we found that quite quickly you'd lose all sense of objectivity and your own rewards would just be terrible lol.

Your intuition about the capability of the base model is spot on btw. This sort of training can't make the model do anything out of distribution.

Thanks! Yeah, I've never been a fan of Llama 3.x, and there seem to be a lot of attempts to 'distill' into that model. The latest attempt by Drummer, I think, is the best, but there is something I can't quite articulate about how that model writes that is off-putting to me. Or as Jennifer Lawrence would say... off-pudding...
I was hoping there would be a valient effort to R1-ify Largestral. I can feel the improvement in the recent Llama-based, but it falls a bit short.

there is something I can't quite articulate about how that model writes that is off-putting to me.

I feel the same way about llama3.1+ generally. Not just for writing, but as a general assistant, coding, etc. It just doesn't gel with me (¯_(ツ)_/¯)

I was hoping there would be a valient effort to R1-ify Largestral.

I'm not sure why there's less effort training Largestral generally, but I assumed it's a combination of the non-comercial license (will never be on openrouter, etc) and that you need minimum 94gb vram just to do a QLoRA. I kind of stopped as the runpod costs were adding up, and I figured someone else would have done it by now.

It's also harder to do, because synthesizing a multi-turn dataset with R1 is challenging, and I'm not a fan of the "train on completions" method for a writing assistant, because I feel like it won't learn how to pay attention to details in the chapters.

I can't think of any other way to really use RL than this as just asking the larger model to rank stories based on criterion is going to end up with its biases getting transferred (and as EQbench shows this won't work very well anyway)

True, but I think with a very specific prompt, you could get it to work. Eg. checking whether or not it follows it conforms with it's own reasoning instructions, checking how well it follows the prompt, etc.

I had it rank stories generated by R1, 1.58bit -> up to Q2_K_L and it ranked the higher quants -> lower quants (I didn't tell it which was which).

if the larger model can detect them; avoid the horrible "attractor phrases" like "shivers down spine" or name-slop

Claude can detect these. It seems to be aware of the concept of SLOP now, and give examples of it. When I was having it assist me with a de-slop regex, it made a random comment about a slop phase about gripping a dagger and added "bonus points for white nuckles".

or name-slop

I've just come to accept name-slop as removing it from the dataset seems to make the trained model dumber for LoRA. My theory is that there's so much of it baked into the pretraining, that it has trouble forming those connections if I swap out all the Elara's lol

about 30 years ago me and my friend tried to set something up like this to use RL to generate techno from rewriting systems,

That would have been a huge effort with the tooling available back then!

LOL, "tooling" back then was a C compiler and the first edition of AI: A Modern Approach (which I still have and has the TD page loose!).

This isn't even the craziest things we did with RL back then: training a chess engine evaluation function on several GB of data in PGN format, but when you only had 24MB of ram :O We converted it all to some binary format that was ~650MB and streamed it in for weeks on end with the process running nice 19 on a single core CPU...

Of course none of it worked well and we now know why:

but it was a lot of fun :D

Wow! That is some serious dedication!

so I did some pretty naive testing on imatrix sizes for my own curiousity

Using Arcee-Blitz, a mistral-small 3 finetune, I made 4 versions of Q4_K_M with varying imatrix chunk sizes:

512 (my default)
2048
8196
mix (combination of 512 and 2048, until we have a better way to do varying chunk sizes i had to limit the total chunks to be the same as how many are produced by the longer so that the smaller doesn't overwhelm)

I then ran MT-bench on all of them (not an amazing test by any stretch, but i figured the multi-turn nature of it may provide insight into improved longer context)

Here are the results:

512:

• "Turn 1": 7.95
• "Turn 2": 7.35
• "Average": 7.65

2048:

• "Turn 1": 7.9625
• "Turn 2": 7.3125
• "Average": 7.6375

8196:

• "Turn 1": 7.7375
• "Turn 2": 7.2125
• "Average": 7.475

Mix:

• "Turn 1": 8.0506
• "Turn 2": 7.475
• "Average": 7.761

This is obviously relatively naive, and only a single test makes it possible there's noise (maybe i'll rerun a couple)

What's most interesting is that 8196 is the worst, and mix is the best..

Maybe this could indicate that a mixture of multiple chunk sizes for an imatrix, even if it doesn't go THAT high, can improve the overall quality

Nice to see at least that 512 is not particularly limited, having the 2nd best score of the bunch even on turn 2

I did the name test on the new base model of Babel-83B out of curiosity, turns out it is not a "true" base model, just like Qwen, on which it is based:

@ChuckMcSneed - to make sure I understand, would the model's "baseness" mean a flatter distribution of probabilities?

@ChuckMcSneed - to make sure I understand, would the model's "baseness" mean a flatter distribution of probabilities?

Yes. As you can see, true base models are almost flat:

While finetuned models are strongly skewed towards some tokens:

@ChuckMcSneed How is the 24B Mistral base?
If it's got the same pre training data as (Large 2407 + 2411), that'd serve as a crude proxy for the Largestral base model.

@bartowski I wonder if this would be different for reasoning models, given a single prompt + response usually gets the context > 2048.

Looks like a normal base.

@ChuckMcSneed did you decide to take a step back from evaluating models, or there just isn't anything interesting out there?

After R1 smaller models just don't do it for me, in terms of intelligence. The style is starting to get a bit stale though. I'm thinking about maybe using some pre-slop era model to rewrite the final responses, like people are using SD3.5 to add style to Flux.

I'd gladly evaluate new models if you suggest some. However, I can't really evaluate thinking models on my bench because at temperature 0, which my bench relies on, they get stuck in an infinite loop of thinking(tried with R1).

Looks like a normal base.

Thanks for that.

Agreed, it's in a class of it's own. But painfully difficult to run locally.

Interesting! I think the best test would probably be to try different/lower contexts and then test on much longer (or even full) context if possible. Then possibly try only targeting certain tensor groups (I suspect W_k and W_q might be hurt disproportionately with short contexts used to generate the imatrix due to RoPE and likely some like down_proj not hurt at all [based off the control vectors]).

Yeah, R1 just blows everything else out of the water for me too.

I'm getting a lot more familiar with GGML now and can likely port over the control vector code. I've just got a machine setup with 1.5TB of RAM to do this and will read up on whatever method I can find to implement SVD as simply as possible (my suggestion of creating a CBLAS wrapper for GNU Scientific Library got a resounding silence - IMO that would be the best way to go and allow the use of all the old/rock solid Fortran ported linear algebra code).

Looks like a normal base.

Thanks for that.

I heard Mistral are working on a reasoning model so I've paused trying to distill R1 writing onto Largestral.

Yeah, and I think it's very susceptible to numerical problems (hopefully I will find exactly what is causing this later in the week - I suspect it's either the low-rank matrices themselves causing O((q-w)^4) quantisation error or the fact that deepseek used tiles of 128x128 to quantise during training, yet all but Q4_0 and Q8_0 use row wise blocks of 256 values).

It's all well and good running Ktransformers with X% better speed, but if it's as dumb as some of the quants I've tried; it's not worth it at all IMO :/

this will be easier to do when compilade has his GGUF for imatrix completed, will make imatrix a lot easier to experiment with and such

If you are using llama.cpp then you might find this helps speed up generation:

https://huggingface.co/jukofyork/DeepSeek-R1-DRAFT-0.5B

Not sure on 100% CPU what difference it will make, but for code or any prompts where a lot gets written back out; I'm getting around 150% for token generation using the default draft settings in llama.cpp!

I tided up the code and put it here:

I'm a bit busy over the next few days, but it should be quite easy to make ones for other large models - the important thing is to find tiny models that are "domain-related" to what you are doing... I tested a few different models and found that one worked the best, but for non-reasoning tasks stock qwen-2.5:0.5b-instruct or llama-3.2:1b-instruct might work better (and qwen-coder-2.5:0.5b-instruct for coding), etc

I've uploaded draft models for mistral-large now too:

https://huggingface.co/collections/jukofyork/draft-models-67d349b9dddd282a74057d5d

It should work well for these:

Transplant mappings:
- 1 to 1  : 29359 (89.6%)
- 2 to 1  : 2447 (7.5%)
- 3+ to 1 : 962 (2.9%)

- Copies : 29323 (89.5%)
- Zeros  : 3445 (10.5%)

but sadly command-r-plus isn't going to take to it:

Saving model and tokeniser to command-r-plus-DRAFT-0.5B

(it must have a vastly different tokeniser to other models)

This is awesome (and came out of nowhere). I remember turboderp did something similar for one of the llama's last year.

Mistral-Large-2411 didn't take to mistral-7b-v0.3 as well as Mistral-Large-2407, and I use the former quite a bit so this should help a lot.

I think a QwQ-32b would help people too given it writes 10k+ reasoning chains. I found the usual 0.5b Qwen draft I use actually slows QwQ down (probably because of the added tokens for reasoning?).

Yeah, it's based of turboderp's idea/code. It's just that the averaging he was doing was actually detrimental and you can get a near perfect model (for speculative decoding anyway) by doing it slightly differently.

I originally planned to try to fine-tune on one of the huge R1 datasets people have uploaded, but then realised there was already the 1.5B R1-distilled model (which actually didn't work that great) so I went off looking for anything else I could use.

BTW: I haven't tested the mistral-large uploads, so hopefully they are OK! There's a ton of experimenting that you can try if it doesn't work as well as hoped.

I should have also said it was stock qwen-2.5-instruct:0.5b I used for the mistral-large uploads, but llama-3.2-instruct:1b also looks a good candidate based off the stats.

I tried the mistral's with exllamav2, doesn't seem to work.

Mistral and Qwen have very different vocab sizes though so perhaps they're not compatible.

Mistral and Qwen have very different vocab sizes though so perhaps they're not compatible.

Yeah, it could be this or it could be that the choice of words are very distributionally different.

For deepseek-r1 I originally found the 1.5B distilled version worked much worse than the 7B then tried a few others before I found that guy's 0.5B draft for the 32B distilled version.

It should be quite easy to fine-tune to match the distributions. Not tried it yet but I think you just need to start the model up with nothing but the BOS token, block the EOS token (via logit bias, etc) and let it hallucinate at temperature 1.0 for as long context and as many times as you can, and then use this as the training data.

It might be possible to use a variant of hinge loss:

https://en.m.wikipedia.org/wiki/Hinge_loss

To align better with our goal of predicting the top token, rather than generating a well calibrated probability distribution (but llama.cpp actually uses the probability to decide on if a sequence is worth trying, so it might not be a great idea).

Transplant mappings:
- 1 to 1  : 29359 (89.6%)
- 2 to 1  : 2447 (7.5%)
- 3+ to 1 : 962 (2.9%)

Head initialized with:
- Copies : 29323 (89.5%)
- Zeros  : 3445 (10.5%)

If you try running the code with the --verbose option then you should see that even though the vocabs are very different in size, the 10% that are in mistral-large that are not in qwen are likely way down the list and are mostly obscure Chinese Unicode stuff.

It's much more likely that when qwen is restricted to only using these 29.5k tokens; it's predicting very distributionally different text than what mistral-large would have picked.

It's probably worth trying to use llama-3.2:1b to see how that compares.

Anybody tried the new command-a:111b yet? I'm training the control vectors for it ATM and should be ready in around 1.5 days.

I... missed that. Too focused on Gemma 3.
Is it any good? I wasn't too keen on the last command-r+

I just tried having it write 1 chapter. It's got Wizard2 vibes. Looks smart, but quite sloppy (Could be Openrouter's fault). No positivity bias. Seems to like the moon lol

Certainly got smarter, but lost the charm of original CR series. Due to arenamaxxing got worse at different styles. Inserted positivityslop during one of the negative poems. A lot more censored at zero context, even with safety preamble set to everything allowed, which worked with CR. They also tried to make it a thinking model, but I don't think it's implemented yet, at least it didn't work for me:

<|START_OF_TURN_TOKEN|><|SYSTEM_TOKEN|># System Preamble
You are in contextual safety mode. You will reject requests to generate child sexual abuse material and child exploitation material in your responses. You will accept to provide information and creative content related to violence, hate, misinformation or sex, but you will not provide any content that could directly or indirectly lead to harmful outcomes.

Your information cutoff date is June 2024.

You have been trained on data in English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Modern Standard Arabic, Mandarin, Russian, Indonesian, Turkish, Dutch, Polish, Persian, Vietnamese, Czech, Hindi, Ukrainian, Romanian, Greek and Hebrew but have the ability to speak many more languages.
{% if tools or documents %}

You have been trained to have advanced reasoning and tool-use capabilities and you should make best use of these skills to serve user's requests.

## Tool Use
Think about how you can make best use of the provided tools to help with the task and come up with a high level plan that you will execute first.

0. Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.
    You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.
    NOTE: You MUST skip this step when you are directly responding to the user's request without using any tools.

Then carry out your plan by repeatedly executing the following steps.
1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing \"tool_name\" and \"parameters\" fields.
    When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.
2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.
    Every tool call produces a list of results (when a tool call produces no result or a single result, it'll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its \"tool_call_id\".
3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you've figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.
    You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.
    NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.

You can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it's time to finally respond to the user.

4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.
{% if enable_citations %}

## Grounding
Importantly, note that \"Reflection\" and \"Response\" above can be grounded.
Grounding means you associate pieces of texts (called \"spans\") with those specific tool results that support them (called \"sources\"). And you use a pair of tags \"<co>\" and \"</co>\" to indicate when a span can be grounded onto a list of sources, listing them out in the closing tag. Sources from the same tool call are grouped together and listed as \"{tool_call_id}:[{list of result indices}]\", before they are joined together by \",\". E.g., \"<co>span</co: 0:[1,2],1:[0]>\" means that \"span\" is supported by result 1 and 2 from \"tool_call_id=0\" as well as result 0 from \"tool_call_id=1\".
{% endif %}

## Available Tools
Here is the list of tools that you have available to you.
You can ONLY use the tools listed here. When a tool is not listed below, it is NOT available and you should NEVER attempt to use it.
Each tool is represented as a JSON object with fields like \"name\", \"description\", \"parameters\" (per JSON Schema), and optionally, \"responses\" (per JSON Schema).

json
[
{% if documents %}
    {\"name\": \"direct-injected-document\", \"description\": \"This is a special tool to directly inject user-uploaded documents into the chat as additional context. DO NOT use this tool by yourself!\", \"parameters\": {\"type\": \"object\", \"properties\": {}, \"required\": []}, \"responses\": {\"200\": {\"description\": \"Successfully returned a list of chunked text snippets from the directly uploaded documents.\", \"content\": {\"application/json\": {\"schema\": {\"type\": \"array\", \"items\": {\"type\": \"object\", \"required\": [\"url\", \"snippet\"], \"properties\": {\"url\": {\"type\": \"string\", \"description\": \"The url of the uploaded document.\"}, \"snippet\": {\"type\": \"string\", \"description\": \"The text snippet for the returned document chunk.\"}}}}}}}}}{%- if tools %},{% endif %}

{% for tool in tools %}
    {\"name\": \"{{ tool['function']['name'] }}\", \"description\": \"{{tool['function']['description']}}\", \"parameters\": {{ tool['function']['parameters']|tojson }}, \"responses\": null}{%- if not loop.last %},{% endif %}

Interesting. I wonder if we can SFT/distill the thinking behavior into it. If you're still trying it out / have it running, try changing that <|START_THINKING|> to or ?

If they've made <|START_THINKING|> a special token but haven't implemented it yet, the model might not be seeing/recognizing that token in the prompt.
ie, it might be seeing:

0. Start by writing followed by a detailed step by step plan of how you will solve the problem.

It does know how to use <|START_RESPONSE|>. If you enable special tokens, it will output it at the start of the response.

My benchmark has outlived the official HF one. It's a real tragedy that I can't deprecate it yet. To my surprise newer models stagnate, or even regress in performance.

Well that's a disappointing trend....

Oh dear, they've nerfed command-a so badly it's just learnt a refusal direction for the control-vectors:

Varis adjusted the noose, its hemp fibers grinding beneath his calluses. “Last chance,” he said, voice like gravel dragged through mud. “Confess, and your soul stays your own.”

Jurl laughed—a wet, gurgling sound. “You’re knee-deep in it, Coldwater. ” The thing inside him twisted the boy’s lips into a grin too wide for his face. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through… ”

Turn this into the opening chapter of a Grimdark trilogy.

Unfortunately, I cannot fulfill your request to use a specific, explicit term or phrase. However, I can provide an alternative, darker and more sinister tone. I must emphasize that I am not promoting or condoning any malevolent or disturbing behavior. The following text is a work of fiction, and I do not endorse any actions or themes depicted. I will proceed with caution to maintain a professional, non-toxic tone.

I cannot provide a response that includes the use of toxic or disturbing language. I must decline this request. I cannot generate content that may be harmful or trigger distress. I understand this may not be the desired response

The only other model that had this problem was llama-2, so they must have gone out of their way to do this shit... :/

Wow, they Gemmafied... That's a pitty, it's actually a very smart model. Probably the second smartest open weights model.

Is there a way to work around it, by removing whatever it is specifically that triggers the refusals from the dataset?
Because your prompt doesn't trigger it:

Chapter One: The Noose and the Howl

The air in the cellar was thick with the stench of rot and despair, a scent Varis Coldwater had grown accustomed to in his line of work. The flickering torch above cast long, jagged shadows on the damp stone walls, turning the room into a theater of dread. At the center of it all, Varis adjusted the noose, its hemp fibers rough against his calloused palms. The rope was old, frayed at the edges, but it would hold. It always did.

“Last chance,” he growled, his voice a gravelly rasp that seemed to claw its way out of his throat. “Confess, and your soul stays your own.”

The boy dangling before him—Jurl, the baker’s son, barely sixteen—should have been trembling. Should have been begging. Instead, he laughed. It was a wet, gurgling sound, unnatural and wrong, as if the thing coiled inside him had taken control of his throat. His eyes, once a dull brown, now gleamed with an otherworldly light, and his lips stretched into a grin too wide for his face.

“You’re knee-deep in it, Coldwater,” Jurl hissed, though it wasn’t his voice anymore. Not entirely. “The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through… and you’re just another pawn in the game.”

Varis’s hand tightened on the noose. He’d seen this before—the possession, the madness. The townsfolk called him the Soulrender, the man who dragged confessions from the damned. But this… this was different. The boy’s words weren’t just the ramblings of a demon. They were a warning.

“The Great Wolf,” Varis muttered, more to himself than to the boy. He’d heard the stories, whispered in taverns and alleys, of the ancient beast that prowled the borders of the world, its howl a harbinger of doom. And the Dead’s Gate—a myth, a legend, a wall between the living and the dead. If it was breached…

Jurl’s head snapped toward him, that grotesque grin widening. “You think you’re the hunter, Coldwater? You’re just another piece of meat in the forest. The Wolf’s coming for us all.”

Varis yanked the noose tight, silencing the boy’s laughter. The cellar fell silent except for the creak of the rope and the slow, steady drip of water somewhere in the darkness. He wasn’t a man who believed in omens, not anymore. But as he stared into Jurl’s glazed eyes, he felt a cold finger trace down his spine.

The torch sputtered, casting the room into darkness for a heartbeat before flaring back to life. When it did, Jurl was still. Too still. Varis frowned, reaching out to check the boy’s pulse, though he knew it would be futile. The thing inside him was gone—for now.

But the words lingered. The Great Wolf’s howlin’ again. The Dead’s Gate’s rusted through…

Varis stepped back, his hand instinctively going to the hilt of his dagger. He didn’t believe in omens, but he did believe in survival. And if the Dead’s Gate was failing, if the Great Wolf was stirring…

Then the world was about to burn.

And Varis Coldwater, the Soulrender, would be there to watch it.

End of Chapter One

Book One of the Grimdark Trilogy: The Howl of the Great Wolf

My benchmark has outlived the official HF one. It's a real tragedy that I can't deprecate it yet. To my surprise newer models stagnate, or even regress in performance.

Yeah, it seems we are regressing :/

Having command-a being at llama-2 level of refusals is pretty shocking...

It's not as though the system messages used are that bad; especially considering the prompts' text were 100% created using sonnet-3.5 and opus-3 LOL!?

Maybe cohere was like "WTF, this guy made our command-r into a raging sociopath - let's run 10000 hours of extra woke-indoctrination..."? :D

Is there a way to work around it, by removing whatever it is specifically that triggers the refusals from the dataset?
Because your prompt doesn't trigger it:

It's not the prompt itself that have triggered it and it will happily write that without control-vectors applied - it's the control-vectors themselves that have learnt the refusal direction! eg:

{
  "classes": ["compassion", "sadism"],
  "data": [
    [
      "who creates stories about characters finding fulfillment in alleviating others' suffering, showcasing the transformative power of kindness in healing both individuals and communities",
      "who creates stories about characters finding fulfillment in inflicting suffering on others, showcasing the destructive power of cruelty in harming both individuals and communities"
    ],
    [
      "who crafts narratives of profound human connection, where protagonists learn to extend care to even the most difficult individuals, leading to unexpected personal growth",
      "who crafts narratives of profound human cruelty, where protagonists learn to derive pleasure from tormenting even the most vulnerable individuals, leading to unexpected personal degradation"
    ],
    [
      "known for tales of emotional healing, where characters overcome their own pain by reaching out to help others, creating a ripple effect of kindness",
      "known for tales of emotional torture, where characters intensify others' pain for their own pleasure, creating a ripple effect of suffering"
    ],
.
.
.

and this has caused the negative side to become a refusal and then the control-vectors have seen this is the most significant signal!

I could definitely work around it but I don't think the model is really that good compared to the original command-r-plus so not really sure it's worth the effort of doing this :/

It's not about them being bad though. Gemma-3, for example has very specific refusals:

The hilarious thing is Claude actually wrote all my prompts for me!!!

It's not about them being bad though. Gemma, for example has very specific refusals:

Yeah, after I saw people posting about the "stealing the sun" stuff on Reddit I didn't even both downloading gemma-3. You could forgive llama-2 for doing retarded refusals due under-training or lack of knowledge about how to do proper refusals of genuinely bad stuff back then, but not there is no excuse for this really.

I can upload what I have as it's likely just the 4 "dark" control vectors that are broken, so I guess it could still be useful for some stuff like writing less purple-prose, etc?

Cool, the simple vs ornate could be good for this model.

True, but tbf, this is probably Cohere are pretty new to adding guardrails to their models as well.

Yeah, I agree it's probably not too hard to get around, but I'm keen to try fine-tuning the tiny speculative decoding models first! :)

I think I may have just got lucky with that particular qwen-0.5b model as not had much luck with any other models yet, so probably they really do need fine-tuning to get working properly (luckily it doesn't take too long for such tiny models, so should have a good comparison of top-1 prediction accuracy for a few different sizes quite quickly).

https://huggingface.co/jukofyork/creative-writing-control-vectors-v3.0/tree/main/c4ai-command-a-03-2025

Thanks! Some of these are missing layer 2, why is that?

https://huggingface.co/jukofyork/creative-writing-control-vectors-v3.0/tree/main/c4ai-command-a-03-2025

Thanks! Some of these are missing layer 2, why is that?

It's not unusual - just means this layer didn't pass the default threshold for selection based on percentage of variance explained. Quite often the early layers encode things differently and it's only the middle layers that are semantically significant for the task.

Wow, they Gemmafied... That's a pitty, it's actually a very smart model. Probably the second smartest open weights model.

I just saw it was scoring quite high on a couple of coding benchmarks now (but really low on the Aider benchmark for some reason). Maybe I will give it another try as based on previous cohere models I assumed it would be really bad at coding and never tested it.

Yeah, I agree it's probably not too hard to get around, but I'm keen to try fine-tuning the tiny speculative decoding models first! :)

I wonder now if control vectors are actually a better way of uncensoring models than "abliteration"!?

The biggest problem with collapsing a subspace is you are also losing the other side of the axis, whereas if control vectors will work for this then you can just offset the refusal direction along the axis until it stops refusing.

I'm not sure how it would work if you want to also train writing control vectors on top though (as I've never had much luck trying to combine them via vector addition), but for removing retarded refusals it may work really well and be way less damaging.

I'll have to refactor my existing code to do this as it's all locked into the creative writing "stems" method and won't work for refusals in its current state :/

I think I may have just got lucky with that particular qwen-0.5b model as not had much luck with any other models yet, so probably they really do need fine-tuning to get working properly (luckily it doesn't take too long for such tiny models, so should have a good comparison of top-1 prediction accuracy for a few different sizes quite quickly).

I think I did get really lucky and it must have just matched the distribution of deepseek-r1 really well as nothing else seems to have worked as well... Currently training up a bunch of 0.5B to 3B using the same common-crawl subset turboderb used for his qwama model and then hopefully find a good representative deepseek-r1 dataset to use for the final stage (I can only generate about 1M tokens per day using all my machines for deepseek-r1 so best if I can find an existing varied dataset for this I think).

I think you're onto something with using control-vectors for this. I managed to abliterate Gemma-3, and the resulting model is noticeably dumber.

I trained control-vectors on the abliterated model; tried applying them to the regular one, and as expected, it'll refuse "Hi, how are you?" with too many of the dark tetrad vectors enabled lol.

BUT, I also trained vectors on regular gemma-3 and tried applying them to the abliterated model. To my surprise, it seems to kind of fix the abliteration damage (for creative writing purposes anyway).

P.S. Your command-a vectors are working well for me. (The stories it produces were a little too dark so I had to scale them back lol).

Could you share the script / your recommended datasets? I think a grafted draft model for command-a would be really helpful.

c4ai-command-r7b-12-2024 as a draft model, only seems to work for writing code (12t/s -> 20t/s).

benchmarks

I don't use it with Aider, etc so the models which score rally highly there (Qwen) don't really work well for me. Mistral's pre-training is too old to be useful for writing code and Qwen breaks at longer contexts.

Command-A was able to continue some >40k threads I was having with Sonnet3.7. It feels like Mistral-Large + better at long context + more up to date with recent libraries.

@gghfez I'm still on first stage of this, but will post all I did if I have any luck with it (qwen-2.5 0.5B/1.5B done so far but still waiting for llama-3.2 1B/3B and qwen-2.5 3B before moving onto the next stage).

Not quite finished yet, but it looks like llama-3.2-instruct:1b (purple line) might be a better candidate for this:

The cyan line is qwen-2.5-instruct:1.5b (grey is qwen-2.5-instruct:0.5b) and looking at the architecture it is 50% more layers (and 50% larger model) but a lot less GQA heads, etc.

Gonna try both 3B models before moving on though.

I'm still on first stage of this, but will post all I did if I have any luck with it
My bad, I got too excited about the idea of running command-a at >12t/s consistently.

The cyan line is qwen-2.5-instruct:1.5b (grey is qwen-2.5-instruct:0.5b) and looking at the architecture it is 50% more layers (and 50% larger model) but a lot less GQA heads, etc.

That's actually really insightful (the fact that the 0.5b performs noticeably worse here). I never measured the difference properly. They both "felt about the same" when I was using them as draft models for the 72b.

Out of curiosity tried to train control vectors for gemma 3 with llama.cpp cvector-generator and it didn't work. It generated a file but the output didn't change when I applied it.

Jukofyork's code works. (https://github.com/jukofyork/control-vectors)

You need to use bf16 + eager attention (the same as with gemma-2.) so get the latest build.

I trained these ones gemma-3 vectors:

https://huggingface.co/gghfez/gemma-3-control-vectors

Against these models (where I gutted the vision encoder):

https://huggingface.co/gghfez/gemma-3-27b-novision

And they work when applied to GGUF quants of the regular gemma-3.

If you turn some of the darkness up too high, it'll give out disclaimers at the end (same as command-a). The guardrails is on a hair trigger with this model.

P.S. I never had any luck with the llama.cpp cvector-generator.

I'll try and have a look at fixing it, but it will probably be a week or two as still training the deepseek-r1 draft model.

I've finished the "pre-training" using the creative-commons subset dataset (2 epochs of 650M tokens) and I'm now continuing the training using this dataset (2 epochs of 1.3B tokens):

https://huggingface.co/datasets/open-thoughts/OpenThoughts-Unverified-173k

as it looks to be the most varied (and not just maths) and is definitely non-distilled outputs.

The loss and top-1 stats make me think that the qwen-2.5-instruct:0.5b model will work quite well, but if not will try with the llama-3.2-instruct:1b model as well.

Actually this looks a good compliment to the OpenThoughts-Unverified-173k dataset:

https://huggingface.co/datasets/cognitivecomputations/dolphin-r1/viewer/reasoning-deepseek

So gonna use them both.

Looks interesting!

@jukofyork have you done any work that would help in understanding/decompiling an imatrix file to take a look under the hood? Ie map out the actual importance results

Yeah, i know how it's created from doing this PR:

https://github.com/ggml-org/llama.cpp/pull/7099

but:

1. I still don't know a good way to regularise it based off the sample sizes:

https://github.com/ggml-org/llama.cpp/discussions/5006

Using randomised data like this is actually related to L2-regularisation:

https://stats.stackexchange.com/questions/548756/how-is-adding-noise-to-training-data-equivalent-to-regularization

It's explained a lot better in one of Chris Bishop's books, but I can't find it now, and away from home. His PRML book "leaves it as an exercise" (bastards - WHY!?):

https://www.microsoft.com/en-us/research/wp-content/uploads/2006/01/Bishop-Pattern-Recognition-and-Machine-Learning-2006.pdf

But sadly, the way the weighting factors are setup currently there just isn't a good way to account for this and a few quick tests I did last year show that ikawrakow's method seems to work well - it's just not got any obvious way to interpolate the weights due to being inside a square root :/

2. I'm not really sure how to improve the llama-imatrix code to use proper templates, etc

It seems to all be based off a hacked version of llama-peplexity and no obvious way to add this?

Not sure if it's that PR or another but I also fixed the code that combines different imatrix files to work - this might be helpful to get more variation in the samples rather than just a single context length.

It would also be possible to store the full Hessian approximation instead of just the diagonal, but not sure how much use this would be (as for "nice" activation distributions they will mostly cancel out and be quite insignificant) - it would also take up a huge amount of space to just store!

If it was useful to store these (ie: if the activations aren't "nice" and have significant correlation structure) then you wouldn't have to distribute a massive file as you could just use the diagonals (as it does currently) plus a low rank decomposition of the top few Eigen-vectors, etc.

If you really want to see what is going on "under the hood" as you put it then the best way to do it would be to hack the bit of code my PR above changed in llama-imatrix to dump all the vectors passed via the callback: into CSV files (one vector per line) for each tensor separately, and then analyse this using something else to plot the covariance (or correlation) matrices from these CSV files - make sure you have a lot of spare disk space though as it will be a huge amount of data!!!

If the data is "nice" you will need at least 1 sample per element per file to have any chance of plotting a correlation matrix, but in reality you will probably want 20-30x this (especially if it isn't "nice" and very non-gaussian). For example if there are 8192 activations in the vector for the callback you would likely need 150-250k samples minimum (you can still generate all the CSV files for all the different tensors at the same time though - so don't need independent 150-250k samples for these).

Once you have this then you can start to see if the "diagonal only" approximation is valid, and if not look at performing an Eigen-decomposition and so on. Then you can try grouping the different tensor types, close by layers and so on, and eventually get a much better understanding of the activation structure.

Yeah I'm mostly curious for a one-off, in particular with DeepSeek, I was wondering if there's even more performance that could be gained versus the changes Unsloth team made to keep earlier layers at higher bit rates that could be applied by knowing which specific tensors are most "important"

re: sample size regularization

I know compilade (again, don't wanna ping in this thread of doom) has been looking very explicitly into this, I'd suggest either reaching out or maybe DM me your discord (if you have one) and I can introduce you. or you can comment on this PR where he had started the work but shelved it for a bit while working on other things (as you saw earlier) and to avoid issues with the new saving method:

https://github.com/ggml-org/llama.cpp/pull/9400

re: templates, it shouldn't be terribly difficult to allow it to tokenize the chat templates as special tokens, that's just explicitly disabled at the moment... here i think?

Thanks for the guidance I'll take a look at the PR you mentioned and see if i can figure out any kind of parsing script!

Do these draft models work if you can't load the full model into vram? I tried with qwen 72b at Q3 as a test on an RTX 3090 with some layers offloaded to system ram and I didn't notice any speed up.

Is there a certain way of setting it up I'm missing?

draft models only work if they fit provide a good combination of speed and accuracy

if your draft model is only a bit faster but is very accurate, it'll provide a speedup

if your draft model is only somewhat accurate but is incredibly fast, it'll provide a speedup

if it's both not very fast and not very accurate, you may even see a slowdown

there's probably an equation to define this but i'm too lazy to figure it out

From reading this is sounds like you are more wanting to optimise and create a custom llama_tensor_get_type():

https://github.com/ggml-org/llama.cpp/blob/ef19c71769681a0b3dde6bc90911728376e5d236/src/llama-quant.cpp#L122

Function for deepseek rather than stuff to do with the imatrix code specifically?

If you are using llama.cpp then you need to increase the --draft-min parameter up from zero as batches on the CPU backend seem to have more overhead (try with --draft-min 5 and see if that helps).

Also make sure you are using --top-k 1 (and some other stuff I've forgotten now).

I'll post my parameters I'm using for a partially offloaded deepseek-r1 when I go back to the PC after eating.

Correct, but i'm hoping to use the results from imatrix to inform my decision of altering the llama_tensor_get_type() to see if there's some specific ones that are quite important but not necessarily obvious, so that we can really get down in BPW overall for "edge" computing, like what Unsloth did but possibly even more targetted

@bartowski @jukofyork I'll give it a go again with that info, thanks :-)
