AI model API price tracker

What each model costs through its API, in US dollars per million tokens. Prices come from official pricing pages where we could read them; a price seen only in one news report is marked “Unconfirmed”. When a price changes, we add a new row, so the history stays.

Current price per million tokens Log scale, so each gridline is ten times the last. Hover or tap a mark for the exact price.
