Gerar músicas com o Lyria

Você pode usar o Lyria para gerar novas faixas de música a partir de comandos. As interfaces compatíveis incluem o Cloud de Confiance console e a API Gemini API.

Testar o Lyria na Agent Platform (Agent Platform Studio)

Antes de começar

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. Configure a autenticação do ambiente.

   Selecione a guia para como planeja usar as amostras nesta página:

   Console

   Quando você usa o Cloud de Confiance console para acessar Cloud de Confiance by S3NS serviços e APIs, não é necessário configurar a autenticação.

   REST

   Para usar as amostras da API REST desta página em um ambiente de desenvolvimento local, use as credenciais fornecidas para a CLI gcloud.

   Instale a Google Cloud CLI e faça login na CLI gcloud com sua identidade federada.

   Saiba mais em Autenticar para usar REST na documentação de Cloud de Confiance autenticação.
