  • GCP project name: adsCopilot
  • GCP project id: adscopilot
  • model: gemini-2.5-pro
  • Google AI Studio tier: tier 2
  • Linked billing account: yes
  • RPD in gcp console(generative ai api): 300
  • RPD in Google AI studio: 50k

We used to has lots of 429 error when calling gemini-2.5 pro. The system showed 300 RPD but at that time we were in tier 1. Now I upgraded it to tier 2 in Google AI Studio for the project, however in gcp console the rpd is still 300 and rpm is not changed to show tier 2 as well.
We need a higher limit to support our business. But why gcp console doesn’t reflect the change from Google ai studio? Can anyone help me with it?

Hey! You should use the AI Studio quota page for your up to date rate limits: https://aistudio.google.com/usage?timeRange=last-28-days&tab=rate-limit. The GCP console just shows all the raw quota objects, inclusive of ones not applicable to your account.

Thanks Logan! Will check the quota working or not. BTW do you know why it didn’t work when I was in tier one in Google AI Studio?
