- **Preferred Operating System(s):** Linux
- **Inference Engine:** [vLLM](https://docs.vllm.ai/en/latest/)
- **Model Optimizer:** [AMD-Quark](https://quark.docs.amd.com/latest/index.html)
  - **Weight quantization:** OCP MXFP4, Static

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

# Model Quantization

The model was quantized from [meta-llama/Llama-3.1-405B-Instruct](https://huggingface.co/meta-llama/Llama-3.1-405B-Instruct) using [AMD-Quark](https://quark.docs.amd.com/latest/index.html). Weights and activations were quantized to MXFP4, and KV caches were quantized to FP8. The AutoSmoothQuant algorithm was applied to enhance accuracy during quantization.

**Quantization scripts:**
```
cd Quark/examples/torch/language_modeling/llm_ptq/
python3 quantize_quark.py --model_dir "meta-llama/Llama-3.1-405B-Instruct" \
                          --model_attn_implementation "sdpa" \
                          --quant_scheme w_mxfp4_a_mxfp4 \
                          --group_size 32 \
                          --kv_cache_dtype fp8 \
                          --quant_algo autosmoothquant \
                          --min_kv_scale 1.0 \
                          --model_export hf_format \
                          --output_dir amd/Llama-3.1-405B-Instruct-MXFP4 \
                          --multi_gpu
```

# Deployment
### Use with vLLM

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

## Evaluation

The model was evaluated on MMLU and GSM8K_COT.
Evaluation was conducted using the framework [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness) and the vLLM engine.
