Our take
Written Aug 3, 2026MiMo-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.
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
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.

GeForce RTX 4090 · 24 GB
Too large for this card. The weights do not fit even with part of them offloaded to system memory.
Apple M1 Pro (16-core GPU) · 32 GB
Too large for this card. The weights do not fit even with part of them offloaded to system memory.
Comfortable fit
Apple M3 Ultra (80-core GPU) · 512 GB
Room to spare. 180.7 GB spare means a 10% error in the size would not change the answer.

All 3 sizes here are calculated, not measured. We hold no measured file for this model, so each size comes from the parameter count and every verdict above inherits that uncertainty.
