Hi,
I’m using the latest Google GenAI Python SDK (google-genai 2.11.0).
Environment:
- Python 3.14.0
- Windows 11
- API key created in Google AI Studio
- Personal Gmail account
- India
What works:
- Authentication succeeds.
- client.models.list() returns all available models successfully.
What fails:
Any call to client.models.generate_content() returns either:
403 PERMISSION_DENIED
“Your project has been denied access. Please contact support.”
or
429 RESOURCE_EXHAUSTED
Quota exceeded with:
GenerateRequestsPerDayPerProjectPerModel-FreeTier, limit: 0
AI Studio Usage page previously showed “Project quota tier unavailable.”
I created a new API key and also tested another Google account. The issue persists.
Is this a project quota issue or does my project require manual access?
Additional information:
- Google AI Studio API Usage initially showed “Project quota tier unavailable” on one project.
- On another project, the Usage dashboard loads normally, but generate_content() still fails.
- I can successfully list models using client.models.list().
- The issue occurs with multiple models including:
- models/gemini-2.0-flash
- models/gemini-3.5-flash
- models/gemini-flash-latest
Thank you.
