My Google account consistently receives “Failed to list models: permission denied” in Google AI Studio.
Details:
- Generative Language API is enabled and shows “Manage” in Cloud Console
- I am Owner of the project (gen-lang-*)
- MFA is enabled
- Issue persists across multiple devices, browsers, and networks
- Creating a new Cloud project does not resolve the issue
- Same behavior occurred on a separate Google account after ~1 month of use
This appears to be an account-level AI Studio / Gemini model entitlement issue rather than a project configuration problem.
Has anyone else experienced this? Is there a path to restore AI Studio access without enabling billing?
