GLM 5.3 Flash
GLM 5.3 Flash is a Zhipu AI open-weights reasoning model, released 20 Aug 2026. Its best configuration ranks #79 of 775 on the BenchLeader Index at 62.8 ±3.9, in the upper half. The ± is the point: 160 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 (70) and lowest in agents & tools (60). At $0.238 per million tokens blended it is cheaper than most ranked models. Output speed of 77 tokens per second puts it slower than most, with a first answer in 28.6 s. It has been measured at 5 reasoning-effort settings; this summary describes the best-scoring one, and the tabs above switch between them. Last measured 19 Oct 2026.

Versions
Zhipu AI has shipped 3 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.

How its index has moved
8 Sept 2026 to 20 Oct 2026- not stated
- max
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.
