Qwen3.6-27B GGUF (AutoRound Quantized)

This repository contains GGUF quantized versions of Qwen/Qwen3.6-27B created using Intel's AutoRound quantization method.

Quantization Details

The models were quantized using various schemes provided by the auto-round tool. For better compatibility and smaller size, we provide unified multimodal projector (mmproj) files in F16, BF16, and F32 formats.

Files and Sizes

File Name	Quant Type	Size	Description
Qwen3.6-27B-Q2_K_S.gguf	Q2_K_S	8.9 GB	Extremely high compression, significant quality loss.
Qwen3.6-27B-Q2_K_MIXED.gguf	Q2_K_MIXED	16 GB	Recommended high-compression option. Uses Q4 for KV cache with good quality. Fast inference.
Qwen3.6-27B-Q3_K_S.gguf	Q3_K_S	12 GB	Very high compression, notable quality loss.
Qwen3.6-27B-Q3_K_M.gguf	Q3_K_M	12 GB	Balanced 3-bit quantization.

Generate the Model

The models were generated using Intel's AutoRound with the following command:

auto-round --model Qwen/Qwen3.6-27B --output_dir ./quantized/ --scheme <SCHEME> --iters 0

Usage with llama.cpp

These models can be used with llama.cpp. For multimodal usage, you must specify the projector file:

./llama-cli -m Qwen3.6-27B-Q4_K_M.gguf --mmproj mmproj-model-f16.gguf --image your_image.jpg -p "Describe this image."

About AutoRound

AutoRound is an advanced quantization technique from Intel that aims to minimize accuracy loss through automated rounding optimization.
