 Anthropic supports [prompt caching](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching) to reduce costs by caching parts of your prompts. Pydantic AI provides three ways to use prompt caching:
 
 1. **Cache User Messages with [`CachePoint`][pydantic_ai.messages.CachePoint]**: Insert a `CachePoint` marker in your user messages to cache everything before it
-2. **Cache System Instructions**: Enable the [`AnthropicModelSettings.anthropic_cache_instructions`][pydantic_ai.models.anthropic.AnthropicModelSettings.anthropic_cache_instructions] [model setting](../agents.md#model-run-settings) to cache your system prompt
-3. **Cache Tool Definitions**: Enable the [`AnthropicModelSettings.anthropic_cache_tool_definitions`][pydantic_ai.models.anthropic.AnthropicModelSettings.anthropic_cache_tool_definitions] [model setting](../agents.md#model-run-settings) to cache your tool definitions
+2. **Cache System Instructions**: Set [`AnthropicModelSettings.anthropic_cache_instructions`][pydantic_ai.models.anthropic.AnthropicModelSettings.anthropic_cache_instructions] to `True` (uses 5m TTL by default) or specify `'5m'` / `'1h'` directly
