Model Quantization

The model was quantized from amd/MiniMax-M2.7-BF16, originally from MiniMax/MiniMax-M2.7, using AMD-Quark. The weights are quantized to MXFP4 and activations are quantized to MXFP4.

Quantization scripts:

export exclude_layers="lm_head *block_sparse_moe.gate* *self_attn*"
python3 quantize_quark.py --model_dir /shareddata/amd/MiniMax-M2.7-bf16 \
                          --quant_scheme mxfp4 \
                          --num_calib_data 128 \
                          --exclude_layers $exclude_layers \
                          --skip_evaluation \
                          --multi_gpu  \
                          --trust_remote_code \
                          --model_export hf_format \
                          --output_dir /shareddata/amd/MiniMax-M2.7-mxfp4

For further details or issues, please refer to the AMD-Quark documentation or contact the respective developers.

Evaluation

The model was evaluated on gsm8k benchmarks using the vllm framework.

Accuracy

Reproduction

The GSM8K results were obtained using the lm-eval framework, based on the Docker image rocm/vllm-dev:nightly.
