Grok 3 Mini Fast

Grok 3 Mini Fast is a SpaceXAI proprietary reasoning model. Its best configuration (high reasoning effort) ranks #263 of 760 on the BenchLeader Index at 53.7 ±1.9, in the upper half. The ± is the point: 276 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 (57) and lowest in knowledge (54). 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 29 Sept 2026.
