## `ik_llama.cpp` imatrix Quantizations of Qwen/Qwen3-Coder-30B-A3B-Instruct
This quant collection **REQUIRES** [ik_llama.cpp](https://github.com/ikawrakow/ik_llama.cpp/) fork to support the ik's latest SOTA quants and optimizations! Do **not** download these big files and expect them to run on mainline vanilla llama.cpp, ollama, LM Studio, KoboldCpp, etc!
*NOTE* `ik_llama.cpp` can also run your existing GGUFs from bartowski, unsloth, mradermacher, etc if you want to try it out before downloading my quants.
Some of ik's new quants are supported with [Nexesenex/croco.cpp](https://github.com/Nexesenex/croco.cpp) fork of KoboldCPP.
These quants provide best in class perplexity for the given memory footprint.
## Big Thanks
Shout out to Wendell and the **Level1Techs** crew, the community [Forums](https://forum.level1techs.com/t/deepseek-deep-dive-r1-at-home/225826), [YouTube Channel](https://www.youtube.com/@Level1Techs)! **BIG thanks** for providing **BIG hardware** expertise and access to run these experiments and make these great quants available to the community!!!
Also thanks to all the folks in the quanting and inferencing community on [BeaverAI Club Discord](https://huggingface.co/BeaverAI) and on [r/LocalLLaMA](https://www.reddit.com/r/LocalLLaMA/) for tips and tricks helping each other run, test, and benchmark all the fun new models!
## Quant Collection
Perplexity computed against *wiki.test.raw*.
These first three are just test quants for baseline perplexity comparison:
* `bf16` 56.894 GiB (16.007 BPW)
- Final estimate: PPL = 9.5334 +/- 0.07560
* `Q8_0` 30.247 GiB (8.510 BPW)
- Final estimate: PPL = 9.5317 +/- 0.07551 (*NOTE* lower than BF16 but didn't use it for "baseline"...)
* `Q4_0` 16.111 GiB (4.533 BPW)
- Final estimate: PPL = 9.7225 +/- 0.07712
## `IQ5_K` 21.324 GiB (5.999 BPW)
Final estimate: PPL = 9.5930 +/- 0.07614
