The lead
Xiaomi's open-weights MiMo-V2.6-Pro ties the new Grok 4.7 on the Artificial Analysis index, both at 46
The gap between the best free-to-download model and a paid frontier release is now zero on one widely used index, on the day both shipped. Grok 4.7 is pitched at coding and multi-hour tasks, with 71 percent on DeepSWE and 46.3 percent on CursorBench.
Xiaomi released MiMo-V2.6-Pro (1 trillion parameters, 42 billion active) and V2.6-Flash (309 billion, 15 billion active) with open weights on Hugging Face, plus RL code and more than 7,000 task environments. Pro scores 46 on the Artificial Analysis Intelligence Index, up from 26 for V2.5-Pro, level with xAI's Grok 4.7 released the same day at 2 dollars in and 6 dollars out per million tokens.
CONVOUse it in an interview when asked about AI costs: a company can now run a model scored level with a paid frontier release on its own servers, so data privacy, not price, becomes the reason to pay a vendor.
