Google Cloud Vertex AI

Sypha facilitates direct integration with Google Cloud’s Vertex AI, an enterprise-grade platform offering high-capacity foundation models, including the full Gemini family and authorized partner models from Anthropic.

Official Site: cloud.google.com/vertex-ai

Strategic Prerequisites

• GCP Infrastructure: An active Google Cloud Project with the Vertex AI API enabled.
• Model Authorization: Access must be explicitly granted for specific engines (e.g., Claude) within the GCP console.
• Primary Authentication (ADC): Sypha utilises Google's Application Default Credentials.
  1. Install the GCP CLI.
  2. Authenticate locally: gcloud auth application-default login
• Secondary Authentication (Service Account): Alternatively, you can utilize a JSON service account key. Ensure the account has the Vertex AI User role.

Authorized Model Registry

Sypha supports the following enterprise engines on Vertex AI:

• Google Gemini: Including the full 2.0 and 1.5 Flash and Pro families.
• Anthropic Claude: Including 3.7 Sonnet, 3.5 Sonnet, and Opus (with optional high-reasoning thinking modes).

Note: For the most recent production IDs, consult the Vertex AI Model Garden.

Configuring Sypha

1. Access Configuration: Click the gear icon in the Sypha sidebar.
2. Set Provider: Choose "GCP Vertex AI" from the provider menu.
3. Configure Authentication Strategy:
   • ADC Execution: If you ran the gcloud command locally, no further entry is required.
   • Service Account Integration: Paste the contents of your JSON key file into the credentials field, or provide the local absolute file path.
4. Define Project & Region: Input your GCP Project ID and the specific region (e.g., us-central1).
5. Assign Primary Engine: Select your model from the selector.

Operational Considerations

• Enterprise Governance: Vertex AI offers robust security and data isolation, making it ideal for corporate environments.
• Fiscal Oversight: Resource consumption is managed via your GCP billing account. Review the Vertex AI Rate Schedule for details.
• Identity Awareness: Ensure the authenticated identity has permission to call aiplatform.googleapis.com.
