PydanticAI Agent Framework to Build Production-Grade Applications with Generative AI

What is PydanticAI?

PydanticAI is a Python agent framework focused on making the creation of robust, production-ready applications with Generative AI less challenging. Developed by the team behind Pydantic, it seamlessly integrates with various large language models (LLMs), such as OpenAI, Anthropic, Gemini, and others. This framework prioritizes type safety and offers structured responses using Pydantic's validation capabilities.

PydanticAI also includes features such as dependency injection for improved testing and iterative development, as well as Pydantic Logfire integration for real-time debugging and performance monitoring. Its design helps developers build AI-driven projects using familiar Python best practices.

Features

Model-agnostic: Supports multiple LLMs including OpenAI, Anthropic, Gemini, Deepseek, Ollama, Groq, Cohere, and Mistral.
Pydantic Logfire Integration: Allows real-time debugging, performance monitoring, and behavior tracking.
Type-safe: Designed to maximize type checking capabilities.
Python-centric Design: Leverages familiar Python control flow and agent composition.
Structured Responses: Uses Pydantic to validate and structure model outputs.
Dependency Injection System: Enables provision of data and services to agent's system prompts, tools, and result validators.
Streamed Responses: Offers continuous LLM output streaming with immediate validation.
Graph Support: Defines graphs via typing hints for complex applications.
