About this model

MiniMax-M3 is a frontier-class foundation model that unites the three capabilities defining today's frontier: a 1M-token context window, frontier coding and agentic performance, and native multimodality — the first open-weight model to deliver all three in a single system.

Replaces MiniMax M2.7: same input and output price, context 205K → 512K, max output 131K → 512K.
