Worth it? GPT-5 Nano is on the price/quality frontier — nothing we track matches its overall Arena score for less. If you can accept a small quality drop, the downgrade calculator finds cheaper options.

Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 28 July 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.
