Pydantic AI
Pydantic AI is a Python framework for building production-grade GenAI applications with type safety and validation. Built by the Pydantic team, it provides model-agnostic abstractions, structured outputs using Pydantic models, dependency injection for testability, streaming support, and human-in-the-loop workflows. Reached v1.0 in November 2024 with stability guarantees. Integrates seamlessly with FastAPI and other Pydantic-based tools.
