LG AI ResearchEXAONE 4.0 32B
EXAONE 4.0 32B is a LG AI Research open-weights reasoning model, released 15 Jul 2025. Its best configuration (thinking reasoning effort) ranks #589 of 785 on the BenchLeader Index at 42.6 ±2.0, in the lower half. The ± is the point: 277 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 reasoning (41) and lowest in knowledge (34). 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 15 Jul 2025.stale: no new result in six months

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

- no reasoning
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.
