Pydantic AI
Agent frameworksA type-safe Python agent framework from the Pydantic team, built around validated structured outputs.
Pydantic AI brings the Pydantic philosophy to agents: define the shape of what you expect, and the framework validates the model's output against it. Agents, tools, and dependencies are all typed, so mistakes surface as type errors rather than runtime surprises.
It is model-agnostic and built by the team behind Pydantic, the validation library most Python AI code already depends on.
Where it's ideally used
A strong fit for Python teams who want agent code that is statically typed and whose outputs are validated by construction.
Where it doesn't fit
Less suited to teams not working in Python, or to free-form agents where rigid output schemas get in the way.
