Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 27 August 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.

Where else you can run GPT-5

The same model is resold by 26 providers we track. The typical one charges 1.2× what the cheapest does — $3.44 against $2.93 per 1M tokens, blended 3:1. Routing the same workload to a different host is often a bigger saving than switching model.

Third-party listings via models.dev, not rates we verify with each host the way we do first-party pricing. Treat them as a shortlist to check, not a quote — and confirm quantisation, context limits and rate limits before switching, since a cheaper host is not always serving the same thing.
