Qwen3.5-35B-A3B
Qwen3.5-35B-A3B is an Alibaba open-weights model, released 24 Feb 2026. Its best configuration (thinking reasoning effort) ranks #304 of 785 on the BenchLeader Index at 52.8 ±7.4, in the upper half. The ± is the point: 406 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 instruction following (71) and lowest in knowledge (40). At $0.688 per million tokens blended it is mid-priced. Output speed of 148 tokens per second puts it in the fastest quarter, with a first answer in 15.5 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 24 Feb 2026.stale: no new result in six months

Versions
Alibaba has shipped 2 models under this name. Each is ranked on its own results; a newer version often has fewer results so far, which holds its index nearer the average until more arrive.

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.
