Instructions to use amd/MiniMax-M2.5-NVFP4 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use amd/MiniMax-M2.5-NVFP4 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="amd/MiniMax-M2.5-NVFP4", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("amd/MiniMax-M2.5-NVFP4", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("amd/MiniMax-M2.5-NVFP4", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	# Model Overview

	- Model Architecture: MiniMaxM2ForCausalLM
	- Input: Text
	- Output: Text
	- Supported Hardware Microarchitecture: AMD MI300/MI350/MI355 (emulation)
	- ROCm: 7.2.2
	- Operating System(s): Linux
	- Model Optimizer: [AMD-Quark](https://quark.docs.amd.com/latest/index.html) (v0.12)
	- Inference Engine: [SGLang](https://docs.sglang.ai/)/[vLLM](https://docs.vllm.ai/en/latest/)
	- Weight quantization: NVFP4, Static
	- Activation quantization: NVFP4, Dynamic


	# Model Quantization

	The model was quantized from [MiniMaxAI/MiniMax-M2.5](https://huggingface.co/MiniMaxAI/MiniMax-M2.5) which was converted to bf16 using [QuixiAI/MiniMax-M2.1-bf16/minimax_to_bf16.py](https://huggingface.co/QuixiAI/MiniMax-M2.1-bf16/blob/main/minimax_to_bf16.py) using [AMD-Quark](https://quark.docs.amd.com/latest/index.html). The weights are quantized to NVFP4 and activations are quantized to NVFP4.


	Quantization scripts:
	```
	cd Quark/examples/torch/language_modeling/llm_ptq/
	export exclude_layers="lm_head block_sparse_moe.gate self_attn"
	export CUDA_VISIBLE_DEVICES=0,1,2,3
	python3 quantize_quark.py \
	--model_dir /MiniMaxAI/MiniMax-M2.5 \
	--quant_scheme nvfp4 \
	--num_calib_data 128 \
	--exclude_layers $exclude_layers \
	--model_export hf_format \
	--trust_remote_code \
	--multi_gpu \
	--output_dir /amd/MiniMax-M2.5-NVFP4

	```
	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](https://github.com/vllm-project/vllm/tree/v0.13.0) framework.

	### Accuracy

	<table>
	<tr>
	<td><strong>Benchmark</strong>
	</td>
	<td><strong>MiniMaxAI/MiniMax-M2.5 </strong>
	</td>
	<td><strong>amd/MiniMax-M2.5-NVFP4(this model)</strong>
	</td>
	<td><strong>Recovery</strong>
	</td>
	</tr>
	<tr>
	<td>gsm8k (flexible-extract)
	</td>
	<td>91.51
	</td>
	<td>91.21
	</td>
	<td>99.67%
	</td>
	</tr>
	</table>



	### Reproduction

	The GSM8K result was obtained using the `lm-evaluation-harness` framework, based on the Docker image `rocm/vllm-dev:nightly_main_20260603`.

	Install the lm-eval `(Version: 0.4.12)` in container first.
	```
	pip install lm-eval
	pip install lm-eval[api]
	```
	#### Launching server
	```
	VLLM_ROCM_USE_AITER=1 vllm serve /amd/MiniMax-M2.5-NVFP4/ \
	--tensor-parallel-size 2 \
	--tool-call-parser minimax_m2 \
	--reasoning-parser minimax_m2 \
	--enable-auto-tool-choice \
	--trust-remote-code
	```
	#### Evaluating model in a new terminal
	```
	lm_eval \
	--model local-completions \
	--model_args "model=/amd/MiniMax-M2.5-NVFP4/,base_url=http://127.0.0.1:8000/v1/completions,tokenized_requests=False,tokenizer_backend=None,num_concurrent=32" \
	--gen_kwargs temperature=1.0,top_p=0.95 \
	--tasks gsm8k \
	--num_fewshot 8 \
	--batch_size 1
