This model was built with deepseek-ai DeepSeek-R1 model by applying AMD-Quark for MXFP4 quantization.

Model Quantization

The model was quantized from deepseek-ai/DeepSeek-R1 using AMD-Quark. Both weights and activations were quantized to MXFP4 format.

Preprocessing requirement:

Before executing the quantization script below, the original FP8 model must first be dequantized to BFloat16. You can either perform the dequantization manually using this conversion script, or use the pre-converted BFloat16 model available at unsloth/DeepSeek-R1-BF16.

Quantization scripts:

cd Quark/examples/torch/language_modeling/llm_ptq/
python3 quantize_quark.py --model_dir $MODEL_DIR \
                          --quant_scheme w_mxfp4_a_mxfp4 \
                          --group_size 32 \
                          --num_calib_data 128 \
                          --exclude_layers "lm_head" \
                          --multi_device \
                          --model_export hf_format \
                          --output_dir amd/DeepSeek-R1-MXFP4
