google doesn’t have enough servers to handle traffic from all paid users
too much demand
the only solution for now is to use sonnet instead of opus
Hi @Zlobor_Dalibor, @Beulah_Kruger
Welcome to the Google AI Forum!!!
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.

Hi @Shivam_Singh2 What we can do as highest plan customer .. Any model filing for last 5 days unusable.. If this is not going to be fixed we migrate directly to antropic this is realt bad user experience..

Cancel your service. If you pay attention to the community, you’ll see that Antigravity isn’t suitable for anything approaching production, and that the amount you pay means nothing.
