Anthropic Claude cache control settings

Fields

enabled: bool

default_ttl_seconds: u64

Default TTL in seconds (maps to “5m” in API). Default: 300 seconds (5 minutes) Note: Anthropic only supports “5m” or “1h” TTL formats.

extended_ttl_seconds: Option<u64>

Optional extended TTL in seconds (maps to “1h” in API if >= 3600). Set to 3600 or higher to use 1-hour caching. Set to None or < 3600 to use default 5-minute caching. Default: Some(3600) for 1-hour caching Note: Using 1h requires the “extended-cache-ttl-2025-04-11” beta header.

Maximum number of cache breakpoints to use (max 4 per Anthropic spec). Default: 4

cache_system_messages: bool

Apply cache control to system prompts by default

cache_user_messages: bool

Apply cache control to user messages exceeding threshold
