Model Quantization
The model was quantized from QuixiAI/MiniMax-M2.1-bf16 using AMD-Quark. The weights are quantized to MXFP4 and activations are quantized to MXFP4.
Quantization scripts:
cd Quark/examples/torch/language_modeling/llm_ptq/
export exclude_layers="lm_head *block_sparse_moe.gate* *self_attn*"
python3 quantize_quark.py --model_dir $MODEL_DIR \
--quant_scheme mxfp4 \
--num_calib_data 128 \
--exclude_layers $exclude_layers \
--skip_evaluation \
--multi_gpu \
--trust_remote_code \
--model_export hf_format \
--output_dir $output_dir
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 vLLM framework, based on the Docker image rocm/vllm-dev:nightly_main_20260211, and vLLM is installed inside the container.
Preparation in container
To download the evaluation script, reinstallation is not required.
# Install vLLM code repo
