When continuing an existing conversation, the previous part of your prompt that is already cached is billed only at 10% of the full cost. By default, Claude Code in billed-per-token setups sets a prompt cache TTL of 5 mins. This means that if you take longer than 5 mins to continue a Claude Code session, you'll pay full price for the whole conversation every turn. https://jomi-se.com/posts/hello-world/ https://jomi-se.com/posts/hello-world/ Fri, 24 Jul 2026 00:00:00 GMT A template post documenting the head-tag contract the aggregator reads.
