Antigravity Ide 2.5.5 - 0% quota on all models http 429

Hello, I’m using Google Antigravity IDE version 2.5.5.

My model quota is stuck at 0%, and none of the available models work. I have already:

  • signed out and signed back in,
  • restarted Antigravity,
  • tried multiple models (Gemini, Claude, and GPT-OSS),
  • reset the onboarding.

The issue persists across all models and I receive quota/resource exhaustion errors.

Could you please check whether there is an account entitlement or quota synchronization issue on my account and refresh/fix it?

Thank you.
