PydanticAI wraps OpenAI's API with a typed model interface, enforcing structured outputs through Pydantic models.
→ Type-safe GPT-4o responses in agent pipelines — structured data comes out of the model, not raw text.
PydanticAI connects to Anthropic's API and enforces Claude's outputs into typed Pydantic models.
→ Fully typed Claude responses with compile-time safety — structured agent data extraction without parsing.
