About Pydantic AI

Pydantic AI offers a Python agent framework from the Pydantic team that brings FastAPI-style type safety to LLM applications. In practice, agents are defined with typed dependencies and outputs, structured results are validated, and tools are plain Python functions. It is aimed at builders who need agents that stay observable, controllable and useful once real users and real data are involved every day.
