What Xiaomi released
Xiaomi introduced MiMo-V2.6-Pro and MiMo-V2.6-Flash on 22 September 2026. Its announcement describes both as natively omnimodal models and lists access through AI Studio, MiMo Code, MiMo Desktop, the MiMo API Platform and OpenRouter. It also introduces Pro-UltraSpeed, with a claimed output speed increase of up to twenty times.
The listed standard API rates per million tokens are $0.14 uncached input and $0.28 output for Flash, and $0.435 input and $0.87 output for Pro. Pro-UltraSpeed is listed at $4.35 input and $8.70 output. Cached input rates differ. The official Flash-RL checkpoint provides a model card and deployment instructions; a downloadable checkpoint and a hosted route are separate deployment choices.
Our recommendation for evaluating the family
Compare Pro and Flash on work with a checkable outcome before paying for faster serving. Give them the same source material, tool budget and acceptance criteria. For a repository change, measure whether the patch is accepted and how much review it needs. Record any retries in the total cost.
If output speed matters, measure the entire task as well as tokens per second. A run dominated by external tools may gain little from faster generation. For local hosting, inspect the checkpoint's hardware requirements and licence before allocating infrastructure. Keep hosted and local results separate in your notes, because the serving stack and configuration can affect both performance and available features. Benchmark rankings can suggest candidates; your own task outcomes should decide a migration.
