All Gemini models in Antigravity fail immediately.

Claude works normally.

GPT works normally.

Only Gemini fails.

User location is not supported for the API use.

This appears to be an Antigravity Gemini provider routing issue because AI Studio works correctly with the same account and same IP.

Hi @dorothy_zhou,

Thank you for reaching out.

To resolve this issue, please follow these steps:

  1. Check Account Country/Region: Visit the Google Terms of Service page while signed into your account to view the registered country associated with your profile. If the listed country is unsupported, submit a request to update your region at https://policies.google.com/country-association-form as detailed in our Geographical Availability FAQ.
  2. Verify Age Eligibility: Confirm that your personal Google Account age is verified at https://myaccount.google.com/age-verification (Age Verification FAQ).
  3. Update & Refresh Local Auth Cache: Ensure you are on the latest version of Antigravity (Google Antigravity - Download), then press Ctrl+Shift+P (or Cmd+Shift+P on macOS) and run Antigravity: Reset Onboarding to refresh your cached account claims.

If the issue persists after completing these steps, please share a fresh Trajectory ID / Trace ID from the latest version.
