Google Cloud GenAI Models

Google Cloud GenAI models can be used for image and video generation:

• Gemini 2.5 Flash
• Gemini 3.0 Pro

Authentication

To use Google GenAI models, you need to set up authentication using either an API key or service account credentials, depending on whether you're using Vertex AI or Google Developer access.

Configuration Options

You can configure authentication via:

• SD.Next: Go to Settings → Model Options → Google GenAI
• Environment variables: Use Google-documented environment variables

Vertex AI (Google Cloud)

Use Vertex AI endpoints for GenAI models. When Vertex AI is enabled, provide service account credentials.
