AI API price changes & new models

Every model we list and every price move we have recorded, newest first. Prices are reconciled against the LiteLLM registry every day, and new models are added the day they appear there.

42 models · 3 price changes · last checked RSS feed

Released uses the provider's release date. Added is the day we started listing a model — the registry doesn't record release dates, so we don't guess one. Corrections to our own data are not shown as price changes.
