1 Cache hits and refreshes on Claude Fable 5.1 and Claude Mythos 5.1 are priced at 0.025x the base input price. All other models use the standard 0.1x multiplier.
The previous table reflects the following pricing multipliers for prompt caching:
- 5-minute cache write tokens are 1.25 times the base input tokens price
- 1-hour cache write tokens are 2 times the base input tokens price
- Cache read tokens are 0.1 times the base input tokens price (see the table footnote for per-model exceptions)
These multipliers stack with other pricing modifiers such as the Batch API discount and data residency. See pricing for full details.
