Pydantic AIai.pydantic.devPydantic AI is the Python AI SDK that provides a typed, extensible agent loop for building AI agents. It enables swapping models across providers (OpenAI, Google xAI, Anthropic, and more) by simple string identifiers without changing agent logic. The framework emphasizes end-to-end typing for models, interfaces, and data, supporting tools and multimodal capabilities to enable scalable, maintainable AI applications.
