Xiaomi MiMo-V2.6-Pro tops open weights leaderboard, trained for $3M

[AINews] Xiaomi MiMo-V2.6-Pro 1T-A42B: the new top Open Weights model, trained for $3M

Xiaomi released the MiMo-V2.6 series. The Pro version ranks #1 among open weights models on the Artificial Analysis Intelligence Index with a score of 46, at a training cost of $3M. A Flash variant targets efficiency, and an UltraSpeed variant offers 20x faster output. The technical report details RL scaling across three axes: larger batches and throughput, richer multi-task environments, and more grader compute. Code and training recipes are open-sourced, but the 7k+ task datasets are not yet released. Former DeepSeek engineer Fuli Luo, now at Xiaomi, previously live-streamed the training runs.

Why it matters: Xiaomi's MiMo-V2.6-Pro hit #1 on the Artificial Analysis open-weights leaderboard with a $3M training budget — price-performance right at the frontier. Flash and UltraSpeed variants cover efficiency and speed use cases, and the tech report details an async RL architecture. Not...
