Pydantic AI

PydanticAI is a type-safe Python agent framework for building production LLM applications with structured data validation.

PydanticAI brings the rigor of Pydantic to agentic workflows. It supports major models including GPT-4o and Claude 3.5 Sonnet through a unified interface. The framework handles structured output validation, tool calling, and dependency injection natively. By using standard Python type hints, it eliminates runtime errors in data extraction (a common pain point in AI development). It is built for engineers who prioritize reliability and clean code in their production AI stack.
