When NOT to use pydantic-ai
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- If your project does not require a typed agent loop or if you prefer a more loosely typed framework.
- When you are working in a language other than Python, as Pydantic AI is specifically designed for Python.
- If you need a tool that focuses solely on a specific interface or model without the need for extensibility across multiple interfaces.
