Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 2 November 2026. Scores are a relative signal, not an absolute measure of capability. A Measured score was voted on directly; an Estimated score is inherited from an identical base model (a regional/creator-prefixed hosting duplicate). See our methodology.
Why picking isn’t obvious
Since fluency is broadly solved, the deciding factors are cost and, for long pieces, output token price. We rank on the overall Arena with a moderate bar and surface the cheapest model that still writes well.
