This is not acceptable experience at all for the ULTRA subscription, this is even gemini model, not the claude one.
No serious work can be done this way, please find a solution. I already canceled the plan but I need to benefit from my money until the cancellation takes effect.
Yeah especially if your model is claude opus.. facing this from last night
Hi all,
Thank you for bringing this to our attention. We have escalated the issue to our internal teams for a thorough investigation.
To ensure our engineering team can investigate and resolve these issues effectively, we highly recommend filing bug reports directly through the Antigravity in-app feedback tool. You can do this by navigating to the top-right corner of the interface, clicking the Feedback icon, and selecting Report Issue.
Happens on Ultra business subscription. This week only. Was fine before, 503 were really rare.
Now it’s every 30sec 1-2 min. (no openclaw or something like that, only manual prompts)
This kind of aggressive throttling is not expected on a paid plan.

I think we will get no answer, they want us to stop using the software and that’s it!
