Pydantic AI

Pydantic AI is a Python agent framework developed by the team behind Pydantic. It provides a type-safe agent loop designed to build production-grade generative AI applications. It leverages Pydantic for validating model outputs against Python type definitions, includes a typed dependency injection system for testing and eval execution, supports streaming responses, and offers model-agnostic switching between OpenAI, Anthropic, Gemini, Groq, Mistral, and local Ollama models.
