Schéma de demande complet

Le schéma de demande est pratiquement identique entre l’API Invoke (streaming et non streaming) et l’API Converse. Il existe des différences subtiles liées au codage des données utiles d’images et de vidéos. Étant donné qu’Amazon Nova Micro ne prend pas en charge les images ou les vidéos en entrée, ces parties du schéma de demande ne s’appliquent pas à Amazon Nova Micro. Sinon, le schéma de demande est le même pour tous les modèles de compréhension Amazon Nova.
