Pydantic AI
Pydantic AI is a Python agent framework built by the creators of Pydantic, designed for building production-grade AI agent applications with type safety and validation at the core. It provides a model-agnostic interface supporting OpenAI, Anthropic, Google, Groq, and other providers, with first-class support for structured outputs validated by Pydantic models. Key features include dependency injection, tool registration, streaming responses, and integration with Logfire for observability. Pydantic AI emphasizes developer experience with familiar Python patterns rather than complex abstractions.
