Llamacpp imatrix Quantizations of Hercules-5.0-Qwen2-1.5B

Using llama.cpp release b3130 for quantization.

Original model: https://huggingface.co/M4-ai/Hercules-5.0-Qwen2-1.5B

All quants made using imatrix option with dataset from here

Filename Quant type File Size Description
Hercules-5.0-Qwen2-1.5B-Q8_0.gguf Q8_0 1646.57MB Extremely high quality, generally unneeded but max available quant.
Hercules-5.0-Qwen2-1.5B-Q6_K.gguf Q6_K 1272.73MB Very high quality, near perfect, recommended.
Hercules-5.0-Qwen2-1.5B-Q5_K_M.gguf Q5_K_M 1125.04MB High quality, recommended.
Hercules-5.0-Qwen2-1.5B-Q5_K_S.gguf Q5_K_S 1098.72MB High quality, recommended.
Hercules-5.0-Qwen2-1.5B-Q4_K_M.gguf Q4_K_M 986.04MB Good quality, uses about 4.83 bits per weight, recommended.
Hercules-5.0-Qwen2-1.5B-Q4_K_S.gguf Q4_K_S 940.30MB Slightly lower quality with more space savings, recommended.
Hercules-5.0-Qwen2-1.5B-IQ4_XS.gguf IQ4_XS 895.72MB Decent quality, smaller than Q4_K_S with similar performance, recommended.
Hercules-5.0-Qwen2-1.5B-Q3_K_L.gguf Q3_K_L 880.16MB Lower quality but usable, good for low RAM availability.
Hercules-5.0-Qwen2-1.5B-IQ3_M.gguf IQ3_M 776.66MB Medium-low quality, new method with decent performance comparable to Q3_K_M.

Downloading using huggingface-cli

First, make sure you have hugginface-cli installed:

pip install -U "huggingface_hub[cli]"

Then, you can target the specific file you want:

huggingface-cli download bartowski/Hercules-5.0-Qwen2-1.5B-GGUF --include "Hercules-5.0-Qwen2-1.5B-Q4_K_M.gguf" --local-dir ./

If the model is bigger than 50GB, it will have been split into multiple files. In order to download them all to a local folder, run:

huggingface-cli download bartowski/Hercules-5.0-Qwen2-1.5B-GGUF --include "Hercules-5.0-Qwen2-1.5B-Q8_0.gguf/*" --local-dir Hercules-5.0-Qwen2-1.5B-Q8_0

You can either specify a new local-dir (Hercules-5.0-Qwen2-1.5B-Q8_0) or download them all in place (./)

Which file should I choose?

A great write up with charts showing various performances is provided by Artefact2 here

The first thing to figure out is how big a model you can run. To do this, you'll need to figure out how much RAM and/or VRAM you have.

If you want your model running as FAST as possible, you'll want to fit the whole thing on your GPU's VRAM. Aim for a quant with a file size 1-2GB smaller than your GPU's total VRAM.

If you want the absolute maximum quality, add both your system RAM and your GPU's VRAM together, then similarly grab a quant with a file size 1-2GB Smaller than that total.

Next, you'll need to decide if you want to use an 'I-quant' or a 'K-quant'.

If you don't want to think too much, grab one of the K-quants. These are in format 'QX_K_X', like Q5_K_M.

If you want to get more into the weeds, you can check out this extremely useful feature chart:

llama.cpp feature matrix

But basically, if you're aiming for below Q4, and you're running cuBLAS (Nvidia) or rocBLAS (AMD), you should look towards the I-quants. These are in format IQX_X, like IQ3_M. These are newer and offer better performance for their size.

These I-quants can also be used on CPU and Apple Metal, but will be slower than their K-quant equivalent, so speed vs performance is a tradeoff you'll have to decide.

The I-quants are not compatible with Vulcan, which is also AMD, so if you have an AMD card double check if you're using the rocBLAS build or the Vulcan build. At the time of writing this, LM Studio has a preview with ROCm support, and other inference engines have specific builds for ROCm.
