I upgraded to tier 1 and I'm still getting the free tier limit

I upgraded to tier 1 and I’m still getting the free tier limit. I upgraded to tier 1 to use Gemini 2.5 pro, but when testing, I’m getting error 429 with a limit of “0”. Is this a general error? Has this happened to anyone else? I need help!

Hi @joss_Alarcon ,
Thanks for reaching out to us. To help diagnose the issue, could you please verify that Cloud Billing is fully enabled and linked to the same Google Cloud project you upgraded in AI Studio?

Yeah, it is.

I’m trying to use 2.5 pro, but the first message alerts me that I’ve exceeded my ‘free tier’ quota, even though I’m already in tier 1.

Proof.

Hi @joss_Alarcon ,

Could you please confirm whether you are using a newly generated API key after upgrading to a paid account?

Thanks.
