XiaomiMiMo-V2.6-Flash
MiMo-V2.6-Flash is a Xiaomi open-weights reasoning model, released 21 Sept 2026. Its best configuration ranks #124 of 756 on the BenchLeader Index at 59.3 ±3.8, in the upper half. The ± is the point: 203 other configurations score within that range, so they and this one cannot be told apart on quality alone — price and speed are what separate them. It scores highest in composite (73) and lowest in agents & tools (54). At $0.175 per million tokens blended it is among the cheapest fifth of ranked models. Output speed of 51 tokens per second puts it slower than most, with a first answer in 42.7 s. Last measured 2 Oct 2026.

How its index has moved
26 Sept 2026 to 5 Oct 2026The index is recomputed from scratch every day, so a line moves when a new benchmark result lands, when a publisher revises a score, or when the models it is normalised against change. Early movement usually means the score is still settling.
