MiniMax M3

Listed as the newest flagship model of MiniMax on its Hugging Face page (checked 2026-09-30). Described by the model card as a native multimodal sparse-attention MoE with weights on Hugging Face.

Specifications (Hugging Face card)

• Parameters: ~428B total / ~23B active; an earlier version of this note listed an MXFP8 440B build; the card re-read on 2026-10-05 does not mention one (it only links MXFP4/MXFP8 quantisation guides), so it is dropped
• Context: 1M tokens
• Modalities: text, image, video (mixed-modality training “from the very first step”)
• Attention: MiniMax Sparse Attention; card claims 9x prefill and 15x decode speedups vs M2 at 1M context
• Reasoning modes: enabled, adaptive, disabled
• Licence: MiniMax Community License (LICENSE file read 2026-10-05): non-commercial use unrestricted; commercial use allowed if “Built with MiniMax M3” is displayed; products with revenue above USD 20M a year need MiniMax’s prior written authorisation, below that a one-time notice to MiniMax; usage restrictions (illegal content, military use, harm to minors, disinformation, hate speech). Read the LICENSE itself before commercial use.
• Release: June 2026 (the card’s arXiv paper 2606.13392, “MiniMax Sparse Attention”, was submitted 2026-06-11; earlier audit text said 2026-06-01 / 05-31 announcement). Exact release day unverified. Repo last updated Jul 23.
• Access: MiniMax Agent, API platform, SGLang / vLLM / Transformers; thinking parameter selects the reasoning mode; recommended temperature 1.0, top_p 0.95 (card, 2026-10-02).

Open items

• Exact release day: not on a primary page (minimax.io news pages 404 or undated); the arXiv paper (MiniMax Sparse Attention, 2606.13392, v1 2026-06-11) says MiniMax-M3 has been released, so release was June 2026 or earlier. Benchmarks are vendor-reported.
