Pydantic AI is a framework built on the popular Python library Pydantic, designed to improve reliability and safety when working with large language models.

It provides structured data validation for LLM outputs, ensuring responses conform to predefined schemas and reducing errors in production environments.

Pydantic AI enables developers to build applications where LLMs produce consistent, machine-usable outputs rather than unstructured text. This is particularly useful for workflows like API responses, database inputs, or structured reporting.
