MiMo-V2.5-Pro — a trillion-parameter model for long agent runs
September 18, 2026
MiMo-V2.5-Pro is live. It is Xiaomi's flagship: a 1.02T-parameter mixture-of-experts model with 42B active per token, a 1M-token context window, MIT licensed, and text only. Xiaomi built it for demanding software engineering and long-horizon agent tasks that span thousands of tool calls. Call it as MiMo-V2.5-Pro.
Xiaomi's published scores:
| Benchmark | Score |
|---|---|
| SWE-bench Verified | 78.9 |
| SWE-bench Pro | 57.2 |
| Terminal-Bench 2.0 | 68.4 |
| τ³-bench | 72.9 |
| ClawEval (pass^3) | 63.8 |
| Humanity's Last Exam | 48.0 with tools, 34.0 without |
It costs 2.5 requests of quota per call and is available on every paid plan and the free tier. Use it for the hard, multi-step coding jobs, and MiMo-V2.5 when you need images, video or audio.
The old MiMo-V2-Flash name is retired. Requests for it now return a message pointing to MiMo-V2.5.
