Vertex AI Provider Support

We've added support for Google Cloud's Vertex AI platform. You can now use Gemini models and other Vertex AI partner models directly in Agenta.

What's New

Vertex AI is now available as a provider across the platform:

• Playground: Configure and test Gemini models and other Vertex AI models
• Model Hub: Add your Vertex AI credentials and manage available models
• Gateway: Access Vertex AI models through the InVoke endpoints

You can use any model available through Vertex AI, including:

• Gemini models: Google's most capable AI models (gemini-2.5-pro, gemini-2.5-flash, etc.)
• Partner models: Claude, Llama, Mistral, and other models available through Vertex AI Model Garden

Configuration

To get started with Vertex AI, go to Settings → Model Hub and add your Vertex AI credentials:

• Vertex Project: Your Google Cloud project ID
• Vertex Location: The region for your models (e.g., us-central1, europe-west4)
• Vertex Credentials: Your service account key in JSON format

For detailed setup instructions, see our documentation on adding custom providers.

Security

All API keys and credentials are encrypted both in transit and at rest, ensuring your sensitive information stays secure.
