MiniMaxOpen WeightsPending Human Review

MiniMax M1 is a hybrid-attention MoE reasoning model derived from MiniMax-Text-01. It combines lightning attention with softmax attention and uses CISPO reinforcement learning to scale long reasoning. A million-token input context supports large documents and repository-level agent tasks. The 40K and 80K thinking-budget checkpoints are represented together as variants, with Apache-2.0 weights available for self-hosting.
