We are encountering “429 Resource Exhausted” errors when attempting to use Gemini 3 model, both through the API and AI Studio, despite remaining within our paid tier limits. Our project ID is 0501972649. Please investigate this issue and provide a solution to restore normal API and AI Studio functionality. All is well for the past few weeks but today we can no longer use the API normally.

Error: 429 RESOURCE_EXHAUSTED. {‘error’: {‘code’: 429, ‘message’: ‘Resource has been exhausted (e.g. check quota).’, ‘status’: ‘RESOURCE_EXHAUSTED’}}

Hi @nash , Thanks for reaching out to us.

The 429 Resource Exhausted error typically indicate that too many requests are being made in a short period. Even with a paid account, rate limits still apply, especially on a per-minute or per-region basis.

To address this:

  • Please check your per-minute and regional quotas in the Google Cloud Console under IAM & Admin > Quotas, filtering by generativelanguage.googleapis.com.

  • Ensure your billing account is correctly linked to the Gemini API project. Some users have found that quota enforcement can behave unexpectedly if the linkage isn’t fully established.
