Caching, batch and other pricing rules
- Cache writes cost 1.25x the input price for a 5 minute cache and 2x for a 1 hour cache. Cache hits cost 0.1x on most models, 0.05x on Opus 5.5 and Sonnet 5.5, and 0.025x on Fable 5.2 and Fable 5.1.
- The Batch API is 50% off input and output, and it stacks with prompt caching.
- Claude Haiku 5.5 charges more per request when the prompt is over 100,000 tokens, counting cache reads and writes.
- Claude 4.7 and later use a tokenizer that produces about 30% more tokens for the same text, so compare costs, not just prices, with older models.
- Data residency in the US (inference_geo) adds 10% on Claude 4.6 and later.
- Web search costs $10 per 1,000 searches on top of tokens.
