## Nauti's Take

Explicit prompt caching is the practical part of this news: deciding yourself which parts of a prompt get cached can cut real cost on long system prompts instead of hoping a black-box heuristic gets it right. The limit shows up with dynamic prompts and sensitive data, where stale context turns into actual errors. Teams on Bedrock get value from testing with realistic repetition rates, measured on hit rate and cost per request.
