    Ridiculously good

    Date: Oct 21 2026
    Summary

    Def an excellent everyday agent model. It is fast, cheap, multimodal, and capable enough that I can use it for serious work without constantly stepping up to a much more expensive flagship model.

    Positive

    It feels noticeably faster than M3 while still being strong enough for coding, research, computer-use tasks, and longer agent workflows. The 1M-token context window is a big advantage too. I can keep large repos, long documents, screenshots, video context, and a lot of prior agent history in the same session without constantly trimming things down. The pricing is probably the best part. At $0.15 per million input tokens and $0.60 per million output tokens, I can run it heavily without worrying that every agent loop is getting expensive. I also like how much MiniMax improved the agent side. M3.1 Flash is aimed at real multi-step work across coding, enterprise automation, computer use, and even cybersecurity, rather than just fast chat responses.

    Negative

    The main downside is that reasoning is always enabled, so it is not quite as lightweight as a pure instant-response model for trivial tasks.
