Llama.cpp hybrid layer quantization of Qwen2.5-VL-32B-Instruct by Alibaba

Original model: https://huggingface.co/Qwen/Qwen2.5-VL-32B-Instruct

The hybrid quant employs different quantization levels on a per layer basis to enable both high performance and small file size at the same time. The quants employed are all K to avoid slow CPU or older GPU processing of IQ quants. For this file the layer quants are as follows:

   LAYER_TYPES='[
   [0 ,"Q4_K_M"],[1 ,"Q4_K_S"],[2 ,"Q3_K_M"],[3 ,"Q3_K_M"],[4 ,"Q3_K_M"],[5 ,"Q3_K_M"],[6 ,"Q3_K_M"],[7 ,"Q3_K_M"],

Comparison:

Quant	size	PPL	Comment
IQ4_XS	17.9e9	6.4	IQ4_XS with default embedding and output
Q4_K_H	18e9	6.15	Hybrid quant with Q4_K embedding Q6_K output

Usage:

Qwen2.5-VL-32B-Instruct is a vision capable model. It can be used together with its multimedia projector layers to process images and text inputs and generate text outputs. The mmproj file is made available in this repository. To test vision mode follow the docs in the mtmd readme in the tools directory of the source tree https://github.com/ggml-org/llama.cpp/blob/master/tools/mtmd/README.md .

Benchmarks:

A full set of vision benchmarks for the model will eventually be given here: https://huggingface.co/spaces/steampunque/benchlm
