Account Unexpectedly Downgraded from Usage Tier 3 to Tier 1

I am writing to report an urgent issue regarding our account’s usage tier. Our organization had previously qualified for and operated at Usage Tier 3 based on our cumulative billing history and payment standing.

However, we noticed on September 22, 2026 that our account was unexpectedly downgraded directly to Tier 1 without prior notice or any pending payment failures.

Current Impact: This sudden reduction in rate limits (RPM/TPM) is severely impacting our production workloads and causing frequent 429 Too Many Requests errors for our active users.

Account Verification Details

  • Previous Tier: Tier 3

  • Current Displayed Tier: Tier 1

  • Payment Method Status: Active and valid

Could you please investigate what triggered this tier recalculation and manually restore our account back to Tier 3 as soon as possible? Please let me know if any additional billing verification is required on our end.

Thank you for your prompt assistance.

Hello @Pallas_AI ,

This is likely happening because of an automated flag on your account. The following should help in this situation…

Check for banners / error callouts in the AI Studio Projects page & the Billing page. Mostly these flags cause visible banners or other errors on these pages with concrete next steps / appeal links.

If the above provides no concrete steps to solve the situation, you should consider applying for a temporary rate limit increase until this can be resolved.

We apologise if the above doesn’t resolve the problem for you immediately. We’re working to improve our messaging in AI Studio and support processes to handle this better.
