GLM-4.5

Reasoning effort

GLM-4.5 is a Zhipu AI open-weights reasoning model, released 28 Jul 2025. Its best configuration ranks #336 of 785 on the BenchLeader Index at 51.7 ±3.8, in the upper half. The ± is the point: 294 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 human preference (59) and lowest in reasoning (47). At $1.00 per million tokens blended it is mid-priced. Output speed of 27 tokens per second puts it in the slowest quarter, with a first token in 8.6 s. It has been measured at 2 reasoning-effort settings; this summary describes the best-scoring one, and the tabs above switch between them. Last measured 22 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.
