September 23, 2026

MiMo-V2.6-Pro is live. The flagship of the V2.6 series: 1.02T parameters with 42B active, a 1M-token context window with up to 128K output, and unlike V2.5 Pro it now reads text, image, video and audio. MIT licensed. Xiaomi positions it for complex projects, long-horizon agent work, security research and high-stakes tasks. Call it as MiMo-V2.6-Pro.

It is a reasoning model: it thinks before it answers, so give it an output budget of a few thousand tokens or short replies come back cut off. It costs 2.5 requests of quota per call and is available on every paid plan and the free tier. MiMo-V2.5-Pro stays available.
