What every Anthropic model costs on the first-party API today, in US dollars per 1M tokens, with the date each price took effect. Retired models show their last price, greyed out. 29 models, 16 with their own price-history page.
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.
Documented since . 29 models tracked, 28 with prices sourced from Anthropic'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.
