# Separate OpenAPI-Schemas für Eingabe und Ausgabe oder nicht

Bei Verwendung von **Pydantic v2** ist die generierte OpenAPI etwas genauer und **korrekter** als zuvor. 😎

Tatsächlich gibt es in einigen Fällen sogar **zwei JSON-Schemas** in OpenAPI für dasselbe Pydantic-Modell für Eingabe und Ausgabe, je nachdem, ob sie **Defaultwerte** haben.

Sehen wir uns an, wie das funktioniert und wie Sie es bei Bedarf ändern können.

## Pydantic-Modelle für Eingabe und Ausgabe

With this feature from **Pydantic v2**, your API documentation is more **precise**, and if you have autogenerated clients and SDKs, they will be more precise too, with a better **developer experience** and consistency. 🎉

## Do not Separate Schemas

Com esse recurso do **Pydantic v2**, sua documentação da API fica mais **precisa**, e se você tiver clientes e SDKs gerados automaticamente, eles serão mais precisos também, proporcionando uma melhor **experiência para desenvolvedores** e consistência. 🎉
