MiMo V2.6 Pro as a Labs experiment, open for a short test window: temporary, not a permanent id. Xiaomi's flagship open model, served from the official MiMo-V2.6-Pro-RL open weights: a 1.02T mixture-of-experts (42B active per token) built for agentic coding and long-horizon tool use, with native image, video and audio understanding and a 1M-token context. Thinking is on by default; the low, medium and high reasoning dials all enable the same full thinking today (fine-grained effort is not differentiated yet), and none turns thinking off. Access is seat-gated through the Labs page while an experiment is live. It is offered at limited capacity and low availability, so expect it to be flaky and to go down under load: crash it, give it a moment, and try again.

Playground closed: Umans MiMo V2.6 Pro Testing
The MiMo V2.6 Pro lab window closed on September 24, 2026 (opened early on September 22). Thanks to everyone who pushed it - text, images, and the thinking dials - and shared findings. The experiment answered its framing question and the model does not earn a permanent slot right now: umans-mimo-v2.6-pro-lab is retired to the past-models list, and there is no successor id. For production work we recommend umans-coder or umans-deepseek-v4.1-flash.

New Labs experiment: Umans MiMo V2.6 Pro Testing
A new lab opened on umans-mimo-v2.6-pro-lab: MiMo-V2.6-Pro-RL served from Xiaomi's official open weights, the flagship checkpoint of the MiMo-V2.6 series: a 1.02T mixture-of-experts (42B active per token) built for agentic coding and long-horizon tool use, with native image, video and audio understanding and a 1M context window. Thinking is on by default; the low, medium and high reasoning dials all enable the same full thinking today, and none turns thinking off. Free and seat-gated while the experiment runs, served at limited capacity and low availability: it is a lab, so expect it to be flaky and to go down under load. Crash it, give it a moment, and try again. The window closes September 24, 2026.
