Vous pouvez utiliser Pydantic pour définir des schémas d’objet dans Python. Selon la version d’OpenAI et Pydantic les bibliothèques que vous exécutez, vous devrez peut-être effectuer une mise à niveau vers une version plus récente. Ces exemples ont été testés contre openai 1.42.0 et pydantic 2.8.2.
