API requests using free tier quota (250 RPD) instead of Tier 1 (10K RPD) despite billing enabled

Gemini API
1

Hi,

I have a Google Cloud project with billing enabled, and AI Studio shows it as “Paid tier 1”. However, when I make API requests using generativelanguage.googleapis.com API, the usage is being counted against the free tier quota (250 requests per day) instead of the Tier 1 quota (10,000 requests per day).

Project Details:

  • Project ID: dark-subject-479914-m7
  • Project Name: Gemini Translation Project
  • AI Studio Tier: Paid tier 1 ✓
  • Billing Account: Active and linked ✓
  • Model: gemini-2.5-flash

Issue:
In Google Cloud Console → Quotas, I can see:

  • “Request limit per model per day for a project in the free tier” (250) - Currently being used (4.8%, 12 requests)
  • “Request limit per model per day for a project” (10,000) - Not being used (0%)

I just created this project today and linked billing immediately. Is there a propagation delay before Tier 1 quotas become active? How can I switch to the paid tier quotas?

Thank you!
