Llamacpp imatrix Quantizations of DeepSeek-Coder-V2-Instruct

Using llama.cpp release b3166 for quantization.

Original model: https://huggingface.co/deepseek-ai/DeepSeek-Coder-V2-Instruct

All quants made using imatrix option with dataset from here

Filename Quant type File Size Description
DeepSeek-Coder-V2-Instruct-Q4_K_M.gguf Q4_K_M 142.45GB Good quality, uses about 4.83 bits per weight, recommended.
DeepSeek-Coder-V2-Instruct-Q3_K_XL.gguf Q3_K_XL 123.8GB Experimental, uses f16 for embed and output weights. Please provide any feedback of differences. Lower quality but usable, good for low RAM availability.
DeepSeek-Coder-V2-Instruct-Q3_K_M.gguf Q3_K_M 112.7GB Relatively low quality but usable.
DeepSeek-Coder-V2-Instruct-Q2_K_L.gguf Q2_K_L 87.5GB Experimental, uses f16 for embed and output weights. Please provide any feedback of differences. Low quality but usable.
DeepSeek-Coder-V2-Instruct-Q2_K.gguf Q2_K 86.0GB Low quality but usable.
DeepSeek-Coder-V2-Instruct-IQ2_XS.gguf IQ2_XS 68.7GB Lower quality, uses SOTA techniques to be usable.
DeepSeek-Coder-V2-Instruct-IQ1_M.gguf IQ1_M 52.7GB Extremely low quality, not recommended.

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/DeepSeek-Coder-V2-Instruct-GGUF --include "DeepSeek-Coder-V2-Instruct-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/DeepSeek-Coder-V2-Instruct-GGUF --include "DeepSeek-Coder-V2-Instruct-Q8_0.gguf/*" --local-dir DeepSeek-Coder-V2-Instruct-Q8_0

You can either specify a new local-dir (DeepSeek-Coder-V2-Instruct-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.
