Hi, my Gemini API tier has suddenly been degraded from Tier3 to Tier1. Since we are on a very urgent project deadline and this issue will significantly impact our progress, could you please assist us at your earliest convenience? Thank you!
Hi
Could you DM me with your project ID ?
I am experiencing a very similar issue.
Timeline:
-
My Gemini API account was upgraded to Tier 2 in late May 2026.
-
After monthly rollover on June 1, all projects unexpectedly reverted back to Tier 1.
Current observations:
-
Billing remains active
-
Postpay enabled
-
API Keys show Tier 1
-
Rate Limits page shows Tier 1
-
No billing suspension or failed payment
Billing account:
019BFB-185187-**** (partially hidden)
This does not appear to be expected behavior because the account had already reached Tier 2 previously.
Could someone help verify whether this is a backend tier recalculation issue?
I can provide screenshots or project information privately if needed.
