Model data verified against GitHub's supported-models page, model-comparison page and changelog on 2026-09-01. Availability is the fastest-moving fact on this site — six models were retired on a single day this year while the reference pages still listed them — so check the model dataset if you are making a decision that depends on one.
Auto model selection carries a 10% discount and excludes models blocked by administrator policy. GitHub does not publish which models it routes to, so this tool does not guess.
