Google AI Studio – Permission Denied Across Models, Usage Dashboard, and Project Creation

Google AI Studio
1

Hello Google AI Studio team,

I’m experiencing what appears to be an account-level permission issue with Google AI Studio.

My account has already completed age verification, and I am the Owner of my existing Default Gemini Project. The project is also currently on Tier 1 with billing linked.

However, AI Studio consistently returns permission errors across multiple features:

  1. In Playground / New Prompt:
    “Failed to list models: permission denied. Please try again.”
  2. In the Usage dashboard:
    Usage statistics and token data fail to load, with a Permission Denied error.
  3. In the Projects page:
    AI Studio displays:
    “Permission denied. Please contact your project administrator for assistance.”
  4. When attempting to create a completely new project:
    “Failed to create project: permission denied. Please try again.”
  5. I previously had an AI Studio access/eligibility issue and was redirected to the Available Regions page. I have since completed Google account age verification, and I can now enter AI Studio, but the permission errors described above remain.

I have also checked Google Cloud IAM. My Google account is listed as Owner of the Default Gemini Project, so this does not appear to be a standard project-level IAM issue.

Could you please check whether my Google account has an incorrect AI Studio/Gemini API entitlement, provisioning status, eligibility restriction, or other account-level flag?

I can provide my Google Cloud Project ID, Project Number, screenshots, billing information, and other diagnostic information privately if needed.

Thank you for your help.
