Gemma 4 E4B

Reasoning effort

Gemma 4 E4B is a Google open-weights reasoning model, released 3 Apr 2026. Its best configuration (thinking reasoning effort) ranks #535 of 785 on the BenchLeader Index at 44.5 ±4.1, in the lower half. The ± is the point: 295 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 knowledge (53) and lowest in multimodal (34). At $0.040 per million tokens blended it is among the cheapest fifth of ranked models. Output speed of 39 tokens per second puts it in the slowest quarter, with a first answer in 51.8 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 3 Apr 2026.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.

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.
