AI Agent Framework, the Pydantic Way

A Python agent framework that brings the FastAPI feeling to GenAI app development. Built by the Pydantic team with model-agnostic support, structured outputs, and type safety.

The agent framework from the Pydantic team: type-safe agents where tools and outputs are validated by pydantic, model-agnostic, with streaming, durable execution (via Temporal integration) and Logfire tracing. The natural choice for Python teams already living in typed Pydantic models.

Who it's for

Python developers who want type-safe, Pydantic-native AI agents with structured outputs by default.
