145| Cache operation | Multiplier | Duration |
146| -------------------- | ------------------------------------------------------------------------------------------------------------------------ | ------------------------------------ |
147| 5-minute cache write | 1.25x base input price | Cache valid for 5 minutes |
148| 1-hour cache write | 2x base input price | Cache valid for 1 hour |
149| Cache read (hit) | 0.1x base input price (0.025x on Claude Fable 5.1 and Claude Mythos 5.1; 0.05x on Claude Opus 5.5 and Claude Sonnet 5.5) | Same duration as the preceding write |

150| 1-hour cache write | 2x base input price | Cache valid for 1 hour |

151Cache write tokens are charged when content is first stored. Cache read tokens are charged when a subsequent request retrieves the cached content. A cache hit costs 10 percent of the standard input price, which means caching pays off after one cache read for the 5-minute duration (1.25x write), or after two cache reads for the 1-hour duration (2x write). On Claude Fable 5.1 and Claude Mythos 5.1, a cache hit costs 2.5 percent of the standard input price ($0.25 USD per million tokens). On Claude Opus 5.5 and Claude Sonnet 5.5, a cache hit costs 5 percent of the standard input price ($0.20 USD per million tokens on Claude Opus 5.5, $0.10 USD on Claude Sonnet 5.5).
