AI Studio Build agent quota error while Gemini 3 chat works — Paid Tier 1

Subject: AI Studio Build agent quota error while Gemini 3 chat works — Paid Tier 1

I have an active Paid Tier 1 Google Cloud project, linked to an active billing
account with a $250 billing-tier cap and available funds.

In Google AI Studio, normal Gemini 3 chat works correctly using my account.

However, AI Studio Build consistently returns:

“Quota exceeded. Please try again later.”

The failure occurs immediately when I enter a trivial Build request, such as:

“Create a simple web page with one heading that says Hello World.”

The app has not been previewed, run, or deployed. Therefore, no application-side
Make. com webhooks, Firebase/Firestore operations, hosting activity, or runtime Gemini
API calls are involved.

Tests and observations:

  • Incognito/private browser test: same Build failure
  • Normal Gemini 3 chat in AI Studio: works
  • AI Studio billing status: Paid Tier 1
  • Billing account: active; $250 tier cap; funds available
  • Total API requests, input tokens, output tokens, and requests per model:
    all below displayed limits
  • Project ID: [PROJECT_ID]
  • Failure date/time/time zone: [DATE, TIME, EDT]

This suggests AI Studio Build/Code Assistant is not receiving the same paid
project/billing entitlement as normal Gemini chat, or a separate Build-agent quota
is incorrectly exhausted.

Please identify the precise quota metric, service, and consumer project used for
the failing Build-agent request and investigate/reset the Build-agent entitlement.
