This model was built with deepseek-ai DeepSeek-R1-0528 model by applying AMD-Quark for MXFP4 quantization.

Model Quantization

The model was quantized from deepseek-ai/DeepSeek-R1-0528 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 amd/DeepSeek-R1-0528-BF16.

Quantization scripts:

cd Quark/examples/torch/language_modeling/llm_ptq/
exclude_layers="*lm_head model.layers.61.*"
python3 quantize_quark.py --model_dir $MODEL_DIR \
                          --quant_scheme w_mxfp4_a_mxfp4 \
                          --group_size 32 \
                          --num_calib_data 128 \
                          --exclude_layers $exclude_layers \
                          --skip_evaluation \
                          --multi_gpu \
                          --model_export hf_format \
                          --output_dir amd/DeepSeek-R1-0528-MXFP4-v2

Deployment

This model can be deployed efficiently using the SGLang and vLLM backends.

Evaluation

The model was evaluated on AIME24, and GSM8K benchmarks using the lm-evaluation-harness framework.

Accuracy

Benchmark	DeepSeek-R1-0528-MXFP4-v2 (non MTP)	DeepSeek-R1-0528-MXFP4-v2 (MTP=3)
AIME24	80.00	83.33
GSM8K	95.00	95.30

Reproduction

The results of AIME24 and GSM8K, were obtained using forked lm-evaluation-harness.
