MiMo-V2.6-Pro (xiaomi/mimo-v2.6-pro) is Xiaomi's flagship open-weights, natively omnimodal reasoning model — a ~1.02T-parameter sparse Mixture-of-Experts with ~42B active parameters, a 1M-token context window, and GQA + sliding-window attention. It scored 46.32 on the AA Intelligence Index (top open-source model at release) and is optimized for long-horizon agentic, coding, and cybersecurity workloads at aggressive cost ($0.435/$0.87 per 1M in/out), though it runs deliberately at ~49 tokens/sec.
