Xiaomi's open MiMo-V2.6 catches up with Grok 4.7
Xiaomi released the MIT-licensed MiMo-V2.6 family. Its Pro model tied Grok 4.7 on an independent intelligence index.
What shipped
On September 22, Xiaomi released the MiMo-V2.6 series: the flagship MiMo-V2.6-Pro, a smaller Flash variant and Pro-UltraSpeed, which gives up to 20 times faster output at the same quality as Pro. The Pro model moved to a native multimodal design that works with text, images, video and audio, keeping a 1M-token context and 128K output limit.
How good it is
MiMo-V2.6-Pro scored 46 on the Artificial Analysis Intelligence Index, level with Grok 4.7, which came out a day earlier. That sets a new ceiling for open-weight models. The models are released under the permissive MIT licence. Xiaomi claims Pro costs between a twentieth and a sixtieth of comparable overseas models.
Why it matters
OpenAI and Anthropic cut prices the same day. An open-weight model this close to closed rivals adds to the price pressure. Because an open model can run on a company's own servers, it can be used without sending data out.
