Scobleizer · x · 2026-09-22

Xiaomi launched MiMo-V2.6 Pro and Flash, two omnimodal models trained via scaled reinforcement learning. Xiaomi claims Pro matches Claude Opus 5 and GPT-5.6 Sol on most agent benchmarks and scores 46 on the Artificial Analysis Intelligence Index — the highest among open-source models — with stronger coding, computer use, 3D reasoning, and creative capabilities.

Commenters highlighted the unusually thorough open release: reward plots, hyperparameters, data mixtures, and even training costs are published, alongside a subset of RL environments and a smaller hobbyist-budget model. Weights, technical report, RL environments, and training code are all open.
