Lyria로 음악 생성하기

Lyria를 사용하여 프롬프트에서 새로운 음악 트랙을 생성할 수 있습니다. 지원되는 인터페이스에는 Cloud de Confiance 콘솔과 Gemini API API가 있습니다.

Agent Platform (Agent Platform Studio)에서 Lyria 사용해 보기

시작하기 전에

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. 환경에 대한 인증을 설정하세요.

   이 페이지의 샘플 사용 방법에 대한 탭을 선택하세요.

   콘솔

   콘솔 Cloud de Confiance 을 사용하여 Cloud de Confiance by S3NS 서비스 및 API에 액세스하는 경우 인증을 설정할 필요가 없습니다.

   REST

   로컬 개발 환경에서 이 페이지의 REST API 샘플을 사용하려면 gcloud CLI에 제공한 사용자 인증 정보를 사용합니다.

   Google Cloud CLI를 설치한 후 제휴 ID로 gcloud CLI에 로그인합니다.

   자세한 내용은 인증 문서의 REST 사용을 위한 인증 을 참조하세요. Cloud de Confiance
