[Antigravity] HTTP 429 on all models - Timer frozen at 4h59m - Google AI Pro (AG-859)

Subject: Manual quota reset request - Google AI Pro Subscriber (Error AG-859)

Account Tier: Google AI Pro (5 TB) - Active since Feb 26, 2026

Problem: HTTP 429 RESOURCE_EXHAUSTED error across all models + quota timer frozen at “4 hours, 59 minutes” without counting down.

Problem Description:
I am an active Google AI Pro subscriber. I have been unable to use Antigravity for ~4 days. Every request to the Agent fails immediately with HTTP 429, even with a simple prompt like “Hello”.

The error occurs across ALL models:

  • Gemini 3.6 Flash (High/Medium/Low)
  • Gemini 3.1 Pro (High/Low)
  • Claude Sonnet 4.6 (Thinking)
  • Claude Opus 4.6 (Thinking)
  • GPT-OSS 120B

Under Settings → Models, all quota bars appear empty and the timer displays “Refreshes in 4 hours, 59 minutes” on ALL models. That timer has been stuck like that since yesterday and is NOT going down (frozen).

However, gemini.google.com/usage shows only 9% daily and 4% weekly usage. I used Antigravity very little this month, so the quota should not be exhausted.

The issue occurs on 2 different Windows computers using the same Google account.

Error Details:

  • Trajectory ID: a4fcbae4-6e0f-43d8-9203-4cf7e82caa87
  • TraceID: 0x7cebbce1335585d9
  • Error: HTTP 429 RESOURCE_EXHAUSTED - “Resource has been exhausted (e.g. check quota).”

Troubleshooting Performed:

  • Logged out and re-authenticated
  • Toggled on “Enable AI Credit Overages” (Available AI Credits = 0)
  • Verified quota at gemini.google.com/usage (shows available)
  • Confirmed on 2 different PCs - same error

Requested Action:
Please check the backend logs for my account and perform a manual quota/entitlements reset. It looks like a quota synchronization bug (possibly AG-859): the dashboard shows available quota, but Antigravity blocks all requests.

Attached Screenshots:

  1. gemini.google.com/usage (9%/4% used)
  2. Antigravity Settings → Models (empty quota, timer frozen at 4h59m)
  3. Google One (active AI Pro plan)
  4. Error 429 in the Agent

Thank you!

@Angel_Cruz try updating antigravity IDE to version 2.5.5. I had the exact same problem and fixed it updating.

Hi @Angel_Cruz,

Thank you for providing the detailed screenshots, Trajectory ID, and TraceID.

To resolve this issue, please follow the below steps:

  1. Update to the Latest Build: As @Jose_Delgado confirmed, updating your IDE to the latest release from antigravity.google/releases includes fixes for this quota timer lock.
  2. Perform a Full Onboarding Reset:
    • Open the Command Palette (Ctrl+Shift+P).
    • Run Antigravity: Reset Onboarding (this flushes %APPDATA%\Antigravity\auth_cache.json).
    • Sign in again with your Google AI Pro account via a fresh browser window to force a new OAuth entitlement exchange.

If the issue still persists , please reach out back to us.
