MiniMax M3

MiniMax M3 is an open-weights model released 2026-05-31, with a 1,048,576-token context and text, image and video input. OpenRouter lists $0.3 per million input tokens and $1.2 output, which is the same as the M2.5 and M2.7 prices, so the larger context does not raise the cost. The licence in our data is open-weights without a standard name, so read the licence text before commercial use. We would suggest it for teams that want a long-context model with open weights at a modest price, and for readers comparing MiniMax's agent-focused releases across versions. The limit is that the M3.1 Flash model costs a quarter as much for simple work, and that we have not tested M3 on coding or agent tasks ourselves. Prices and specifications come from the OpenRouter listing we checked on 31 October 2026, and we have not tested the model ourselves.
