Prompt caching

Anthropic supports prompt caching with Claude, which allows Claude models to cache system messages and conversation history between requests to improve performance and reduce costs. Prompt caching is generally available for:
  • Claude 4 Sonnet
  • Claude 3.7 Sonnet
  • Claude 3.5 Sonnet
  • Claude 3.5 Haiku
To enable caching of the system message and the turn-by-turn conversation, update your model configuration as follows:
config.yaml
models:
  - name: Anthropic
    provider: anthropic
    model: claude-sonnet-4-20250514
    apiKey: <YOUR_ANTHROPIC_API_KEY>
    roles:
      - chat
    defaultCompletionOptions:
      promptCaching: true
