Qwen3-32B-AWQ-Pile

Qwen3-AWQ Highlights

• Open-source. Calibration data, evaluation tools, and model quantization algorithms are fully open-source.
• Precision. Achieves accuracy comparable to the bf16 models.
• Process. Provides detailed quantization and testing workflows for easy reproducibility.
• Faster. The AutoQuant kernel has been released in vLLM, delivering superior performance compared to the Marlin kernel.

Quantization

• calibration data

The model quantization process uses the Pile dataset for calibration. You can obtain the data from https://huggingface.co/datasets/mit-han-lab/pile-val-backup/.

• quantization algorithm

The model quantization process employs two quantization algorithms: AWQ and GPTQ. We have modified AutoAWQ and AutoGPTQ frameworks for this purpose, which are directly usable.

Evaluation

For deployment, we use vllm==0.8.5 and create an OpenAI-compatible API endpoint:

nothink:

VLLM_USE_MODELSCOPE=True CUDA_VISIBLE_DEVICES=0,1 vllm serve /model  --gpu-memory-utilization 0.9 --served-model-name Qwen3-32B --trust_remote_code --port 48001 --tensor-parallel-size 2

think:

VLLM_USE_MODELSCOPE=True CUDA_VISIBLE_DEVICES=0,1 vllm serve /model --gpu-memory-utilization 0.9 --served-model-name Qwen3-32B --trust_remote_code --port 48001 --tensor-parallel-size 2 --enable-reasoning --reasoning-parser deepseek_r1

Sampling parameters are set to match https://huggingface.co/Qwen/Qwen3-32B#best-practices.

To facilitate testing and reproducibility, we utilized the open-source evalscope tool to evaluate the accuracy of both bfloat16 (BF16) and quantized models.

git checkout -b v0.17.0 tags/v0.17.0
cd evalscope/
