+
+MiniMax-M3 is a native multimodal model with 1M context. It has ~428B parameters and ~23B activated parameters.
+
+**Highlights:**
+- **Native Multimodality:** M3 undergoes mixed-modality training from the very first step, enabling deeper semantic fusion across text, image, and video.
+- **Context Scaling via Sparse Attention:** M3 introduces MiniMax Sparse Attention (MSA) to improve long context efficiency. M3 delivers 9× prefill and 15× decode speedups compared to M2 at 1M context, reducing per-token compute to 1/20.
+- **Coding & Cowork Capability:** M3 achieves frontier-level performance across long-horizon agentic benchmarks, excelling in both coding and cowork.
+
+MiniMax-M3-MXFP8 is the MXFP8 quantized variant of [MiniMax-M3](https://huggingface.co/MiniMaxAI/MiniMax-M3), a native multimodal model with 1M context. It has ~428B parameters and ~23B activated parameters.

+
+## MiniMax Sparse Attention (MSA)
+
+M3 is powered by [**MiniMax Sparse Attention (MSA)**](https://github.com/MiniMax-AI/MSA), a high-performance sparse attention operator designed for million-token contexts. Compared with GQA, MSA dramatically reduces the attention compute and memory footprint while preserving model quality.

+
+## How to Use
+
+- [MiniMax Agent](https://agent.minimax.io/)
+- [MiniMax API](https://platform.minimax.io/)
+
+M3 supports two reasoning modes:
+- **thinking** — for complex reasoning, agentic tasks, and long-horizon collaboration.
+- **non-thinking** — for latency-sensitive scenarios such as chat and code completion.
+
+## Local Deployment
+
+Download the model:
+
+```bash
+hf download MiniMaxAI/MiniMax-M3 --local-dir MiniMax-M3
+```
+
+We recommend the following inference frameworks (listed alphabetically) to serve the model:
+
+- [SGLang](https://docs.sglang.io/) - see  [SGLang cookbook](https://docs.sglang.io/cookbook/autoregressive/MiniMax/MiniMax-M3).
+
+- [vLLM](https://github.com/vllm-project/vllm) - see [vLLM recipes](https://recipes.vllm.ai/MiniMaxAI/MiniMax-M3).
+
+- [Transformers](https://github.com/huggingface/transformers) - see [Transformers docs](https://huggingface.co/docs/transformers/model_doc/minimax_m3_vl).
+
+
+### Inference Parameters
+
+We recommend the following parameters for best performance: `temperature=1.0`, `top_p=0.95`, `top_k=40`.
