FastAPI 0.126.0 entfernte die Unterstützung für Pydantic v1, während `pydantic.v1` noch eine Weile unterstützt wurde.

/// warning | Achtung

Das Pydantic-Team hat die Unterstützung für Pydantic v1 in den neuesten Python-Versionen eingestellt, beginnend mit **Python 3.14**.

Dies schließt `pydantic.v1` ein, das unter Python 3.14 und höher nicht mehr unterstützt wird.
