Qwen3.5-122B-A10B

Reasoning effort

Qwen3.5-122B-A10B is an Alibaba open-weights reasoning model, released 24 Feb 2026. Its best configuration ranks #256 of 785 on the BenchLeader Index at 54.3 ±5.9, in the upper half. The ± is the point: 333 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 maths (60) and lowest in coding (46). At $1.10 per million tokens blended it is pricier than most ranked models. Output speed of 57 tokens per second puts it slower than most, with a first token in 1.3 s. It has been measured at 3 reasoning-effort settings; this summary describes the best-scoring one, and the tabs above switch between them. Last measured 23 Oct 2026.

Reasoning-effort configurations

The same model behaves differently depending on how much it is allowed to think. Each row is one setting, scored only on the benchmarks that were run at that setting. “Not stated” collects results from publishers that did not say which setting they used; for a reasoning model that is usually its thinking mode, but we do not assume it. Pick a setting here or at the top of the page to see its price, speed and category scores.

The 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.
