AI / LLM Market: Xiaomi MiMo-V2.6-Pro tops open weights, trained for $3M
Xiaomi released MiMo-V2.6-Pro, a natively omnimodal open-weights model with 1.02T total / 42B active parameters, trained for $3M (about 130 hours and 75B tokens). It debuts as the top open-weights model on Artificial Analysis' Intelligence Index (46) with cost efficiency at $0.435/M input and $0.87/M output tokens, under an MIT license. Xiaomi also open-sourced the RL training environment code and recipes, but not the full 7k+ task datasets, signaling an emphasis on transparency in RL training.
A major open-weights model release from a new major Chinese lab, challenging existing leaders with cost efficiency and RL transparency, highly relevant to AI-driven advertising.
