Long running agentic products like Claude Code are made feasible by prompt caching which allows us to reuse computation from previous roundtrips and significantly decrease latency and cost. What is prompt caching, how does it work and how do you implement it technically? Read more in @RLanceMartin's piece on prompt caching and our new auto-caching launch. At Claude Code, we build our entire harness around prompt caching. A high prompt cache hit rate decreases costs and helps us create more generous rate limits for our subscription plans, so we run alerts on our prompt cache hit rate and declare SEVs if they're too low. These are the (often unintuitive) lessons we've lear
