MiniMax M3 (2 minute read)

TLDR AI Models

Summary

MiniMax introduces M3, the first open-weights model to combine coding, agentic, and multimodal capabilities with up to 1M context via sparse attention.

MiniMax M3 is an open weights model that achieves frontier-level performance on coding and agentic work. The model supports image and video input and can operate a desktop computer. It uses a new attention architecture that enables context scaling and can support ultra-long context windows of up to 1 million tokens. The model is available through MiniMax Code, the Token Plan, and MiniMax's API services.
