CODE 500 for 3.1 PRO LOW / HIGH -- 3 FAST works without problems!

Hello, PRO user, updated antigravity to 1.18.3,

with the new models I always get the following error

{
“error”: {
“code”: 500,
“message”: “Internal error encountered.”,
“status”: “INTERNAL”
}
}

With the “old” 3 FAST, no problems.

What I already tried:

  • reinstall
  • remove .gemini .antrigravity
  • reinstall multiple times
  • logoff - logon from account

but nothing of above worked…

any clue?

Same here, i couldnt use gemini 3 for the past 2 days, and now, after update, with gemini 3.1 pro i only could send 1 prompt who stopped in middle of execution, and now im getting the error

Agent terminated due to error

You can prompt the model to try again or start a new conversation if the error persists.See our for more help.

Hope they fix this fast, this is the 3rd day… i dont want to go back to Cursor

Same here Just waiting team to solve this out (AI Ultra)

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.

I just tried again and it finally works without any further intervention.

This is still broken for me. All morning and still ongoing. I am planning on cancelling my ultra subscription. More than a couple minutes of downtime for something like this is insane for a modern software company. What happened to Google?

I have had this issue the last several days as well since updating my Antigravity client. I have noticed this is only affecting Antigravity on Mac using my Google Workspace account. Antigravity on Windows with my personal account has been working fine. Additionally, other coworkers with Antigravity on Mac have not had the issue.
