AI Studio Build Agent returns "Quota exceeded" on Paid Tier 1 despite available quota

Hello,

I am experiencing a persistent “Quota exceeded. Please try again later.” error in Google AI Studio Build.

The issue appears to be specific to the AI Studio Build Agent rather than my application or normal Gemini API usage.

Account / project status:

  • Google AI subscription: Google AI Pro
  • Gemini API billing: Active
  • Gemini API tier: Paid Tier 1
  • Project: Default Gemini Project
  • Project ID: gen-lang-client-06318914..
  • Prepaid Gemini API balance is available
  • AI Studio Rate Limit dashboard currently shows:
    • Antigravity RPM: 0 / 30
    • Antigravity TPM: 0 / 200K
    • Antigravity RPD: 0 / 1K
  • AI Studio Usage dashboard currently shows no API usage data.

What happens:

The Build Agent was previously working normally on my project.

It then started returning:

“Quota exceeded. Please try again later.”

I initially suspected that the issue might be related to my project size, conversation history, or the complexity of my coding requests.

I therefore performed a minimal test.

I opened a NEW Build chat and sent only:

“Do not modify any existing files. Just reply with ‘Test successful’.”

Even this minimal request returned:

“Quota exceeded. Please try again later.”

So the issue occurs even without asking the agent to inspect, modify, build, or test the application.

Normal Gemini chat responses work.

The problem appears to occur specifically with the AI Studio Build Agent.

Could you please check whether there is a separate Build Agent quota, entitlement, or backend issue affecting my account/project?

In particular, I would appreciate confirmation of:

  1. Which exact quota is causing the “Quota exceeded” error.
  2. Whether AI Studio Build has a separate quota from the published Gemini API RPM/TPM/RPD limits.
  3. Whether my Paid Tier 1 entitlement is correctly applied to AI Studio Build.
  4. Whether there is any account, project, or Build Agent state preventing execution.
  5. Whether this is a known current issue with the Build Agent.

I can provide screenshots, App ID, Project ID, or other diagnostic information if required.

Thank you.

I’m running into a similar issue specifically with the Google AI Studio chat interface.

I’m a tier 2 paid member with plenty of credit.

Despite low rate usage and plenty of spend headroom (see screenshot). The chat function often says quota reached and needs approx 24 hours to reset. I can overcome this by using a lower Gemini model (e.g. 3.7 instead of 3.8)

I’m happy to pay more—how can I lift or increase this quota restriction?

Hello,

@Idris_Ozturk: Could you please share your Applet ID so we can look into your build agent logs?

@Tian_Tang: Could you please share which specific screen you are seeing the error in (along with screenshots)? Additionally, please send your project ID that has the Tier 2 billing account linked via direct message so we can check your account setup.

Applet ID: 6a0eefb5-a243-440d-8663-4558e8496dff
Project ID: `potent-bloom-2367..
Billing Tier: Paid Tier 1 / Prepay

Hello Google AI Studio Team,

I am experiencing the same persistent “Quota exceeded. Please try again later.” issue in Google AI Studio Build.

Billing is active and the project is on Paid Tier 1 / Prepay. Even after starting a completely fresh chat inside the existing app, the simple prompt “Reply exactly: OK. Do not modify any project files.” immediately fails with “Quota exceeded” and shows “Ran for 0s”.

My Gemini API quota is clearly not exhausted:
RPM: 3 / 1,000
TPM: 29 / 2M
RPD: 3 / 10K

The Usage dashboard also shows very low usage. I also observed one 503 ServiceUnavailable error.

Could you please inspect the Build Agent logs for this Applet and check whether there is an entitlement/backend quota issue?

I can provide screenshots and the exact failed-run timestamp if needed. Thank you.
