Qwen3-VL-4B-Instruct-per-grp-quant

• Introduction

  This model was quantized using amd_quark-0.11

• Quantization Strategy

  • Quantized Layers: All linear layers
  • Weight: uint4 asymmetric per-group with group_size=128.

• Quick Start

1. Downalod the Qwen3-VL-4B-Instruct model.
2. Run the quantization script in the example folder using the following command line:

   python run_qwen3_vl_4b_quant_model.py
   

Evaluation

Quark currently uses perplexity(PPL) as the evaluation metric for accuracy loss before and after quantization.The specific PPL algorithm can be referenced in the quantize_quark.py. The quantization evaluation results are conducted in pseudo-quantization mode, which may slightly differ from the actual quantized inference accuracy. These results are provided for reference only.
