MiniMax M3.1 Flash is free on every plan

minimax/minimax-m3.1-flash is free on AnyRouter right now. The catalog shows $0 for input and $0 for output, and credits are not deducted.

It is free on every plan. You need to be signed in, and that is all. There is no daily cap. Free-model requests share a limit of 2400 requests per minute per API key.

We have not set an end date. We will say so here and in the release note if the price changes.

MiniMax built M3.1 Flash for multi-step agent work, reading real codebases, fixing bugs and building features. It has a 1M-token context window, accepts text, image and video, and always reasons. You set the effort with reasoning_effort.

A 1M window lets you put a large repository or a long log in one request. That suits coding agents.

Add :free to pin the free route. The request never falls through to a paid one.

anyr claude --model minimax/minimax-m3.1-flash

• Model page — live routes and price.
• All free models — the full free list.

The model is also listed through Ollama Cloud. Add your own Ollama key under Dashboard → BYOK and requests go to your Ollama account.

Ollama is offering this model free on its own cloud until 23:59 UTC on October 22, 2026. That is Ollama's offer on your Ollama account, not an AnyRouter price. After that date, Ollama's own terms apply.
