Genera música con Lyria

Puedes usar Lyria para generar pistas de música originales a partir de instrucciones. Entre las interfaces compatibles, se incluyen la Cloud de Confiance consola de y la API de Gemini API.

Prueba Lyria en Agent Platform (Agent Platform Studio)

Antes de comenzar

1. In the Cloud de Confiance console, on the project selector page, select or create a Cloud de Confiance project.

   Roles required to select or create a project

   • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
   • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

   Go to project selector

2. Enable the Gemini Enterprise Agent Platform API, if it is not already enabled.

   Roles required to enable APIs

   To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

   Enable the API

3. Configura la autenticación para tu entorno.

   Selecciona la pestaña según cómo planeas usar las muestras de esta página:

   Console

   Cuando usas la Cloud de Confiance consola de para acceder a los Cloud de Confiance by S3NS servicios y las APIs, no necesitas configurar la autenticación.

   REST

   Para usar las muestras de la API de REST incluidas en esta página en un entorno de desarrollo local, debes usar las credenciales que proporciones a la gcloud CLI.

   Instala Google Cloud CLI y, luego, accede a gcloud CLI con tu identidad federada.

   Para obtener más información, consulta Autentícate para usar REST en la Cloud de Confiance documentación de autenticación de.
