Our take

Written Aug 3, 2026

MiMo-V2.5 is a large downloadable model from Xiaomi that accepts text, images, audio and video, and can handle over one million tokens in a single request. Its permissive MIT licence and strong measured coding score make it a notable option for long-document and coding-heavy workloads.

Who should pick it

Choose this for long-context document analysis at over one million tokens, or for coding workloads where its measured coding score matters. Good for multimodal pipelines and products needing a permissive commercial licence. Skip it if creative writing quality is central, if you need consistent throughput guarantees, or if you need to know per-token compute cost for self-hosting.

The case for it

  • Extremely long request limit for a downloadable model: 1,050,000 tokens.
  • Permissive MIT licence allows commercial use, modification and redistribution without copyleft.
  • Strong measured coding performance relative to its other skills: 57.5 points above its overall text score.
  • Wide provider availability with a roughly fourfold spread on input rates, so shopping around pays off.

The case against it

  • Creative writing is a clear relative weakness, sitting 39.6 points below its overall text score and 97.1 points below its coding score.
  • No disclosed active-parameter count, so true per-token compute cost for self-hosting is unknown.
  • Throughput inconsistent and unmeasured on three of ten tracked offers; hard-prompt strength does not lift overall text rating proportionally.

Nobody we watch has scored MiMo-V2.5 for this. We would take the rating from Arena Agent (IPS).

WritingWe do not rate this

Scored, not ratedThe placings are on the right.

Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage. So we show where MiMo-V2.5 placed and give it no mark out of five.

These tests check whether a model follows instructions — a precondition for all the work above, but not a measure of how well that work is done, which is why they get no rating.
