Model pricing

30-day rate lock

Rates on this sheet are promised for 30 days, until 2026-11-09. A sheet that would raise a promised rate is refused before it is served, and each request is charged the lowest price still promised for its usage.

Each price sheet promises its rates for 30 days from the sheet's date (the date its version starts with). A later sheet may lower a rate at once; a sheet that would raise any rate of a model (input, output, cached input, cache writes, batch or long-context rates, or the private price) while an earlier sheet still promises the lower one is refused before it is served, so the sheet in force is at or below every rate still promised. A request is charged the lowest price, for its own usage, among the sheet in force and every sheet whose promise still holds, and its receipt and usage row name that sheet.
