In einigen Fällen ist es sogar möglich, sowohl Pydantic‑v1‑ als auch Pydantic‑v2‑Modelle in derselben **Pfadoperation** Ihrer FastAPI‑App zu verwenden:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

Im obigen Beispiel ist das Eingabemodell ein Pydantic‑v1‑Modell, und das Ausgabemodell (definiert in `response_model=ItemV2`) ist ein Pydantic‑v2‑Modell.
