GenAI Agent Framework, the Pydantic way
Documentation: ai.pydantic.dev
Pydantic AI is a Python agent framework designed to help you quickly, confidently, and painlessly build production grade applications and workflows with Generative AI.
Yet despite virtually every Python agent framework and LLM library using Pydantic Validation, when we began to use LLMs in Pydantic Logfire, we couldn't find anything that gave us the same feeling.
We built Pydantic AI with one simple aim: to bring that FastAPI feeling to GenAI app and agent development.
Enables you to systematically test and evaluate the performance and accuracy of the agentic systems you build, and monitor the performance over time in Pydantic Logfire.
Build agents from composable capabilities that bundle tools, hooks, instructions, and model settings into reusable units.
Define agents entirely in YAML/JSON — no code required.
Agent / Skill / MCP / Workflow fit.
