MiniMax M2 230BA10B — 8% of Claude Sonnet's price, ~2x faster, new SOTA open model
MiniMax M2, an open-weight sparse MoE model by Hailuo AI, launches with ≈200–230B parameters and 10B active parameters, offering strong performance near frontier closed models and ranking #5 overall on the Artificial Analysis Intelligence Index v3.0. It supports coding and agent tasks, is licensed under MIT, and is available via API at competitive pricing. The architecture uses full attention, QK-Norm, GQA, partial RoPE, and sigmoid routing, with day-0 support in vLLM and deployment on platforms like Hugging Face and Baseten. Despite verbosity and no tech report, it marks a significant win for open models.
