After losing hours with Google Support (who couldn’t fix it because Billing Support Live Chat and AI Studio/Gemini support are separate), I finally got it fixed.
It is a state-sync bug on Google’s end where a healthy billing account fails to sync. You can bypass it in 2 minutes by doing this:
-
Open Google AI Studio, and create a new Project.
-
Link your existing, valid billing profile to this new project.
Creating a new project apparently forces a fresh sync between Billing and AI Studio, immediately restoring Tier 3 limits. Hope this saves someone from losing hours/customers like I did!

It was resolved indeed 4 days ago, before it just happened again today…
I don’t even know what to say anymore. How is it possible?
Thanks Aaskash! We had this issue (from tier 2 → downgraded to tier 1 without any notice). It would be nice if this can be restored asap since our production enviroment is impacted right now.
It was fixed for me 5 hours ago and now it just happened again, this is just fascinating… I don’t know what to do anymore
same here, was fixed, now issue back… has influence on the stability of our production environment, so would need a definitive fix
