About

MiniMax M3 is a multimodal mixture-of-experts model from MiniMax with roughly 428B total and 23B activated parameters and a 1M-token context window. According to the model card, it is trained on mixed modalities from the first step, covering text, image and video input, and is aimed at coding, agentic and "cowork" tasks.

It uses MiniMax Sparse Attention (MSA), a sparse attention operator for million-token contexts. MiniMax reports 9x prefill and 15x decode speedups over M2 at 1M context. The model supports three reasoning modes via a thinking parameter: enabled, adaptive and disabled. A technical report is on arXiv (2606.13392).

Weights are on Hugging Face under the MiniMax community license (not an OSI open-source license) and can be served with SGLang, vLLM, Transformers, KTransformers and unsloth. It is also available through the MiniMax API and the MiniMax Code agent product. A YouTube creator mentioned a smaller FP8 version and placed it among the leading open models on Artificial Analysis; this was not verified here.
