Root Cause

Please confirm whether personal Google AI Pro / Google One AI Pro subscribers are currently supposed to have access to Gemini CLI through OAuth. If yes, this seems to be a bug in authorization or entitlement handling. If no, the current behavior is confusing because sign-in succeeds but all requests fail with 403.

What happened?

I can sign in to Gemini CLI successfully with my personal Google account that has an active Google AI Pro / Google One AI Pro subscription. However, every prompt fails with 403 PERMISSION_DENIED.

So this is not a sign-in problem. OAuth works, but actual usage is denied.

I have already tried signing out and signing back in, and the issue still happens on every request.

TL;DR

The issue is likely due to a mismatch between the expected authorization permissions for Google AI Pro / Google One AI Pro subscribers and the actual permissions granted to the Gemini CLI, resulting in a 403 PERMISSION_DENIED error.

Guidance

  • Verify the documentation for Google AI Pro / Google One AI Pro to confirm if subscribers are supposed to have access to Gemini CLI through OAuth.
  • Check the Gemini CLI documentation to see if there are any specific requirements or restrictions for using the CLI with Google AI Pro / Google One AI Pro subscriptions.
  • Investigate the authorization flow to ensure that the correct permissions are being requested and granted during the OAuth process.
  • Consider reaching out to the Gemini CLI support team to confirm if this is a known issue or a bug in the authorization or entitlement handling.

Notes

The issue seems to be related to the authorization and entitlement handling of the Gemini CLI, but without more information about the expected behavior and the actual implementation, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Wait for further clarification from the Gemini CLI support team or the Google AI Pro / Google One AI Pro documentation to confirm the expected behavior and potential workarounds.
