We have to wait. The new Gemini 3.1 Pro model looks promising because it’s supposedly less prone to hallucinations. If this is confirmed, I might renew my subscription, which I’ve already canceled. After what Gemini 3 Pro or Flash did… basically every model right now is better than Gemini. Well, we’ll see. Comparison of AI Models across Intelligence, Performance, Price | Artificial Analysis

I’m running into the same problem. I have no idea how to update other than just exiting the app and opening it again.

I updated it via apt, it found the latest antigravity in the repo and worked, to the degree that it ever does.

Later it told me I could access Gemini 3.1, but I shall pass for the moment as my quotas would probably vanish in 5 mins!

From my point of view, nothing has improved. It still doesn’t follow instructions and keeps making excuses, maybe just a bit more sophisticated ones – more of a storyteller than an agent.

Downloading the latest installer and running it (without uninstalling) worked. I’m now on the last version and I still have all my settings, which is what I was worried about.

This is literally the google experience the from memes.

Mate you literally have Antigravity, equipped with the most potent brains in the entire world to assist you with this, just ask Gemini 3 about that error and it’ll automatically do it for you. You just have to update to the latest version of antigravity

I totally get the frustration. The quickest way to fix this is to head over to antigravity.google, grab the latest version, and run the installer again. This fresh install should clear up any issues and get you back on track.
