Pydantic AI is a type-safe Python SDK for building AI agents and LLM applications, with a typed agent loop, structured outputs, tool calling, MCP support, realtime voice, image generation, and embeddings. The same agent can run behind a web frontend, in the terminal, on voice calls, or on durable background queues, with model providers swapped via a string.
Use cases
- build production AI agents in python with type safety
- extract structured data from llm outputs with pydantic validation
- connect agents to mcp servers for external tools
- stream agent events to a chat frontend
- run long-running durable agents on temporal
- build a terminal coding agent with file and shell access
- swap llm providers without changing agent code
- add memory and sub-agents to a multi-agent system
When to choose
- you want typed, validated structured outputs from llms
- you need model-agnostic agents across openai, anthropic, and other providers
- you want mcp, streaming UI protocols, and durable execution in one sdk
- your team already uses pydantic and fastapi
When to avoid
- you need a javascript or go-first agent framework
- you want a no-code or low-code agent builder
- you only need raw llm api calls without an agent abstraction
