Claude Code’s 1-Hour Prompt Cache Upgrade
Episode 13
Published 4 months, 3 weeks ago
Description
Claude Code v2.1.108 extends prompt caching from 5 minutes to 1 hour, making long system prompts and big repo contexts stay warm through real work sessions instead of expiring during normal breaks. The episode also covers the `DISABLE_TELEMETRY` bug fix, the optional 5-minute fallback, deprecated Bedrock compatibility, and why any prefix change still invalidates the cache immediately.
