  - **Input:** Text
  - **Output:** Text
- **Supported Hardware Microarchitecture:** AMD MI350/MI355
- **ROCm**: 7.0
- **PyTorch**: 2.8.0
- **Transformers**: 4.53.0
- **Operating System(s):** Linux
- **Inference Engine:** [SGLang](https://docs.sglang.ai/)/[vLLM](https://docs.vllm.ai/en/latest/)
- **Model Optimizer:** [AMD-Quark](https://quark.docs.amd.com/latest/index.html) (V0.10)

This model was built with deepseek-ai DeepSeek-R1-0528 model by applying [AMD-Quark](https://quark.docs.amd.com/latest/index.html) for MXFP4 quantization.

# Model Quantization

The model was quantized from [deepseek-ai/DeepSeek-R1-0528](https://huggingface.co/deepseek-ai/DeepSeek-R1-0528) using [AMD-Quark](https://quark.docs.amd.com/latest/index.html). 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](https://github.com/deepseek-ai/DeepSeek-V3/blob/main/inference/fp8_cast_bf16.py), or use the pre-converted BFloat16 model available at [amd/DeepSeek-R1-0528-BF16](https://huggingface.co/amd/DeepSeek-R1-0528-BF16).

**Quantization scripts:**
```
cd Quark/examples/torch/language_modeling/llm_ptq/
exclude_layers="*self_attn* *mlp.gate.* *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
```

# Deployment

This model can be deployed efficiently using the [SGLang](https://docs.sglang.ai/) and [vLLM](https://docs.vllm.ai/en/latest/) backends.

## Evaluation

The model was evaluated on AIME24, GPQA Diamond, and MATH-500 benchmarks using the [lighteval](https://github.com/huggingface/lighteval/tree/v0.10.0) framework. Each benchmark was run 10 times with different random seeds for reliable performance estimation.

### Reproduction

The results of AIME24, MATH-500, and GPQA Diamond, were obtained using forked [lighteval](https://github.com/zhaolin-amd/lighteval/tree/v0.10-release-custom) and vLLM docker (emulation qdq) `rocm/vllm-private:pytorch-vllm-gfx950-mxfp4-mxfp6-v3`.
