MiniMax-M3.1-Flash, free until Oct 23

October 21, 2026

New model: MiniMax-M3.1-Flash. A multimodal reasoning model for coding and agent work: reads text, images and video, 1M-token context, function calling, thinking always on. Call it as MiniMax-M3.1-Flash from the API, your coding tools, Koda, or pick it in Chat.
Free for every plan until the end of Oct 23 (IST). Requests to it use none of your quota while the offer runs, free plan included. A fair-use limit of 40 requests a minute per account keeps it fast for everyone. After the offer it becomes a regular Pro-tier model at 1× a request.
