Description

Hello, i am testing a port of my agentic app to Pydantic AI, and i would like to request easy support prompt caching ["cache-control"] = {"type": "ephemeral"} for Anthropic models.

I find that my costs are reduced by half when i enable this feature in my current app, and i think lots of people would find it beneficial. At the moment i am caching tool calls and system prompt.

Thanks in advance.
