Schema di richiesta completo

Lo schema di richiesta è quasi identico tra l’API Invoke (streaming e non streaming) e l’API Converse. Esistono lievi differenze relative alla codifica del payload di immagini e video. Poiché Amazon Nova Micro non supporta immagini o video come input, le parti dello schema di richiesta relative a questi contenuti non si applicano ad Amazon Nova Micro. Per il resto, lo schema di richiesta è lo stesso per tutti i modelli di comprensione di Amazon Nova.
