Claude API price history

Verified Source Anthropic release notes7 dated entriesUSD per 1M tokens

Two newer Claude models launched cheaper than the model they follow: Claude Opus 5.5 is 20% below Claude Opus 5 on every token price, and cache reads on Claude Fable 5.1 cost a quarter of what they cost on Claude Fable 5. Anthropic's release notes state no list price change to an existing Claude model in the period covered. The other entries are launches at an unchanged price, plus one planned increase that Anthropic cancelled.
