Antigravity in Gemini Enterpriselink

Integration with Gemini Enterprise and Gemini Enterprise Agent Platform enables enterprise development teams to deploy Google Antigravity using models hosted directly within your organization’s Google Cloud infrastructure. Every session runs under Google Cloud’s enterprise security controls, data residency guarantees, and the Google Cloud Terms of Service.

Supported products: Antigravity 2.0 Antigravity CLI

Overview & Key Benefitslink

You can use Antigravity in two ways:

• Agent Platform - Connect directly to Agent Platform to use Antigravity with pay-as-you-go billing.
• Gemini Enterprise Subscription - Connect with your Gemini Enterprise Standard or Plus license to get access to included quotas, managed overages as well as advanced administrative controls.

By connecting Google Antigravity to your Google Cloud project, your organization gains:

• Enterprise Governance: Operates under your existing Google Cloud Terms of Service with centralized administrative controls.
• Data Residency & Security: Satisfies private networking (VPC Service Controls) and regional data residency constraints. Enterprise prompts, responses, code, and telemetry are never stored outside your private environments.
• Consumption Billing: Integrates directly with your Google Cloud Billing account for unified consumption invoicing at Agent Platform pricing.

Before You Beginlink

Make sure your environment meets the following prerequisites:

• A Gemini Enterprise Standard or Gemini Enterprise Plus subscription. (Other subscription tiers, such as Gemini Enterprise for Business, are planned for future releases but are not currently supported).
• A Google Cloud project ID and a deployment location—global, us, or eu—that carries your license.
• For Bring Your Own Identity (BYOID), an administrator must configure Cloud Identity or Workforce Identity Federation for your organization.

IAM Roles & Permissions Matrixlink

Before configuring your environment, review the Identity and Access Management (IAM) roles required for initial project setup and model inference:

Administrator Setup Guidelink

Gemini Enterprise Setuplink

To setup Gemini Enterprise subscriptions, follow the official Google Cloud onboarding guide.

Google Cloud Environment Provisioninglink

Complete the following three steps to provision your Google Cloud project and enable API access.

Step 1: Select or Create a Google Cloud Project

Select an existing project or create a dedicated project for your team’s Antigravity workloads.

Step 2: Verify Cloud Billing

Ensure that Cloud Billing is active for your selected Google Cloud project. You can inspect your project’s billing status in the Cloud Console.

Step 3: Enable the Agent Platform API

Enable the Agent Platform API (aiplatform.googleapis.com) to allow Antigravity clients to connect to your project’s model endpoints.

Sign In & License Selectionlink

Google Antigravity uses a single sign-on (SSO) flow. When you sign in with your corporate business account, your license tier is automatically detected without requiring manual tier selection.

Sign-In Workflowlink

1. Start Antigravity 2.0 or the Antigravity CLI.
2. Select Sign in to open the browser authentication flow.
3. Choose Business account (subject to the Google Cloud Terms of Service).
4. Select Continue with Google Cloud (or configure Advanced SSO / WIF).
5. Complete authentication in your browser.
6. Once authenticated, the License Selector displays your assigned licenses. Confirm the project linked to your license and select it.
7. Alternatively, select Other to self-assign a license by entering your project ID and selecting a location (global, us, or eu).

Bring Your Own Identity (BYOID / WIF)link

Bring Your Own Identity (BYOID) uses Workforce Identity Federation (WIF) to let your organization authenticate through an external identity provider, such as Okta, instead of a standard Google Account.

Configuring BYOIDlink

1. In Antigravity, select Business account.
2. Select Advanced WIF Configuration.
3. Enter the WIF Configuration String provided by your organization’s administrator.
4. Complete sign-in through your federated identity provider.
5. Select or self-assign a license from the License Selector.

Application Default Credentials (ADC) in Antigravity CLIlink

For headless environments and automated terminal workflows, the Antigravity CLI supports authentication using Google Cloud Application Default Credentials (ADC).

Setting Up ADClink

1. Generate local Application Default Credentials for your project using the Google Cloud SDK:
   bash

   content_copy

   gcloud auth application-default login --project {GCP_PROJECT}

2. Verify that your credentials file exists. On Linux and macOS, the default path is:
   bash

   content_copy

   ~/.config/gcloud/application_default_credentials.json

3. Enable ADC authentication by exporting the required environment variable:
   bash

   content_copy

   export AGY_ADC_AUTH=true

4. To sign out of ADC, unset the environment variable and restart your terminal session:
   bash

   content_copy

   unset AGY_ADC_AUTH

Regional Endpoints & Capability Matrixlink

Antigravity CLI and Antigravity 2.0 support multi-region deployment endpoints to satisfy regional data residency requirements:

For full endpoint specifications, consult the Deployment Endpoints Documentation.

Troubleshooting & Diagnosticslink

Common Sign-In & License Issueslink

• No Licenses Appear During Setup: Licenses are assigned by your organization’s Google Cloud administrator. If the License Selector is empty, contact your administrator to ensure your account has been granted access to a Gemini Enterprise Standard or Plus license.
• Missing BYOID Sign-In Option: Ensure you are running the latest release of Antigravity 2.0 or the Antigravity CLI, as enterprise authentication and BYOID support are included natively in all recent releases.
• Browser URL Allowlist Advisory: When a browser URL allowlist is configured in admin controls, allowlisted URLs may still be blocked in Antigravity. Admin URL allowlists are currently being integrated and are not yet honored.

Known Limitationslink

BYOID / WIF login:

• When signing in with the Advanced SSO option (BYOID / Workforce Identity Federation), a small number of users are unexpectedly logged out and must sign in again after restarting Antigravity 2.0 or the Antigravity CLI.
• Affected users must re-authenticate on restart.

Important API Provisioning Advisorylink

Sharing Diagnostics with Supportlink

When contacting Google Cloud Support, include the diagnostic log file from your most recent session:

• Antigravity CLI (Linux and macOS):
  bash

  content_copy

  ~/.gemini/antigravity-cli/cli.log

• Antigravity 2.0 (macOS):
  bash

  content_copy

  ~/Library/Logs/Antigravity/language_server.log
