This model was built with deepseek-ai DeepSeek-R1 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](https://huggingface.co/deepseek-ai/DeepSeek-R1) 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 [unsloth/DeepSeek-R1-BF16](https://huggingface.co/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" \
                          --skip_evaluation \
                          --multi_device  \
                          --model_export hf_format \
                          --output_dir amd/DeepSeek-R1-MXFP4-Preview
```

# Deployment

### Reproduction

The result of AIME24 was obtained using [SGLang](https://docs.sglang.ai/) while result of GSM8K was obtained using [vLLM](https://docs.vllm.ai/en/latest/). Both evaluations were conducted via forked [lm-evaluation-harness](https://github.com/BowenBao/lm-evaluation-harness/tree/cot).
