Prices are per 1M tokens for the base context tier. — means the provider doesn't document the rate; n/a means it isn't offered. Models marked "long-context tier" charge more for prompts over a context threshold; those prices are on the model page, or in the long-context table below. Cache write shows the shortest cache duration where durations are priced separately. Restricted access: the price is public, but only approved customers can use the model.

Long-context tiers

Prices for prompts over the context threshold, for models without their own page. Models with a page list every tier there.

Methodology and coverage

Documented since . 67 models tracked, 67 with prices sourced from OpenAI's official pricing pages, announcements or changelog (directly or through Wayback Machine captures). A price only counts when an official source shows it; dates first seen in captures are shown as a range, never as an effective date. How this works.
