MiMo-V2.6-Pro / Flash

Since Week 38 2026, where these two models were only a live training dashboard with nothing shipped yet. Both have now actually shipped: MIT-licensed weights on Hugging Face as MiMo-V2.6-Pro-RL and MiMo-V2.6-Flash-RL, plus a MiMo-V2.6-Distill-Qwen-9B finetune. Pro is a 1.02T-parameter mixture-of-experts with 42B active and a 1M-token context, scoring 46.32 on the Artificial Analysis Intelligence Index v4.3, a third-party index rather than a self-reported number. Flash is 309B total with 15B active. Both are omnimodal, text, image, audio and video in, text out. Xiaomi states the final RL run cost roughly $2.62M for Pro and $850K for Flash.
