Membuat musik dengan Lyria

Anda dapat menggunakan Lyria untuk membuat trek musik baru dari perintah. Antarmuka yang didukung mencakup konsol Cloud de Confiance dan Gemini API.

Mencoba Lyria di Agent Platform (Agent Platform Studio)

Sebelum memulai

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. Siapkan autentikasi untuk lingkungan Anda.

   Pilih tab untuk melihat bagaimana Anda berencana menggunakan contoh di halaman ini:

   Konsol

   Saat menggunakan konsol Cloud de Confiance untuk mengakses layanan dan API Cloud de Confiance by S3NS , Anda tidak perlu menyiapkan autentikasi.

   REST

   Untuk menggunakan contoh REST API di halaman ini dalam lingkungan pengembangan lokal, gunakan kredensial yang Anda berikan ke gcloud CLI.

   Instal Google Cloud CLI, lalu login ke gcloud CLI dengan identitas gabungan Anda.

   Untuk mengetahui informasi selengkapnya, lihat Melakukan autentikasi untuk menggunakan REST dalam dokumentasi autentikasi Cloud de Confiance .
