Model Overview
Description
MiniMax-M3 is a multimodal model with frontier-level coding and agentic capabilities, built on a Mixture-of-Experts architecture with a 1M-token context window. The model processes text, image, video, and computer use inputs and produces text outputs, with emphasis on long-horizon coding tasks, agentic and tool-use workflows, and long-form video understanding. The NVIDIA MiniMax-M3 NVFP4 model is quantized with Model Optimizer.
This model is ready for non-commercial use.
Third-Party Community Consideration:
This model is not owned or developed by NVIDIA. This model has been developed and built to a third-party's requirements for this application and use case; see link to Non-NVIDIA MiniMax-M3 Model Card.
License/Terms of Use:
GOVERNING TERMS: Use of the checkpoints is governed by the MiniMax Community License. Additional Information: Built with MiniMax M3.
Deployment Geography:
Global
Use Case:
Use Case: MiniMax-M3 is intended for multimodal understanding across text, image, and video; long-form video understanding (up to 30 minutes); long-horizon coding tasks (8+ hours); agentic and tool-use workflows; and design and creative tasks. The model supports two reasoning modes switchable per request: thinking mode for complex reasoning and agentic tasks, and non-thinking mode for latency-sensitive scenarios.

Post Training Quantization
This model was obtained by quantizing the weights and activations of Minimax-M3 to NVFP4 data type. This optimization reduces the number of bits per parameter from 8 to 4, reducing disk size and GPU memory requirements by approximately 2x.
Usage
To serve this checkpoint with vLLM, you currently need the nightly docker image that includes MiniMax-M3 NVFP4 support from vllm-project/vllm#46380 (not yet in a stable release). Launch the nightly image and run the sample command below:
vllm serve nvidia/MiniMax-M3-NVFP4 \
--tensor-parallel-size 8 \
--block-size 128 \
--tool-call-parser minimax_m3 \
--reasoning-parser minimax_m3 \
--enable-auto-tool-choice
Evaluation
NVFP4 Quantization Accuracy (vs. FP8 baseline):
| Precision | GPQA Diamond | AA-LCR | τ²-Telecom | MMMU-Pro | SciCode |
|---|---|---|---|---|---|
| FP8 | 92.53 | 76.62 | 92.22 | 71.97 | 49.90 |
| NVFP4 | 91.92 | 75.60 | 91.89 | 71.01 | 49.70 |
Baseline: MiniMax-M3 in its native MXFP8 format. Benchmarked with temperature=1.0, top_p=0.95, max num tokens 65536.
Model Limitations:
The base model was trained on data that contains toxic language and societal biases originally crawled from the internet. Therefore, the model may amplify those biases and return toxic responses especially when prompted with toxic prompts. The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive.
Ethical Considerations
NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications. Developers should work with their internal model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
