Pydantic AI
A Python agent framework from the Pydantic team, built around type safety and structured, validated outputs. It is model-agnostic, works with local models, and brings a clean, familiar developer experience to building agents.
Strengths
- Type-safe with structured, validated outputs by default
- Model-agnostic, so local models work through an OpenAI-compatible endpoint
- Clean, Pythonic design with a good developer experience
Weaknesses
- A newer framework, with a smaller ecosystem than LangChain
- Less focused on complex multi-agent orchestration than LangGraph or CrewAI
- Python only, so no help outside that ecosystem
