If you’ve been trying to access Gemini 3.1 Pro within the Antigravity app but it’s still showing that gemini 3.1 pro is not available on this version. Please upgrade to the latest version. here is the solution!
Many users who downloaded Antigravity before the 3.1 Pro release are finding that the app doesn't always auto-update to the latest model. If you're stuck on the previous version, follow these simple steps to get it running:
✅ The Solution:
Uninstall your current Antigravity app or stay with your previous version of the antigravity itself
Head over to the official Antigravity website.(https://antigravity.google/download)
Download and install the latest version fresh.
Open the app and log back in.
Boom! Gemini 3.1 Pro should now be showing as Activated and ready for use.
It seems the internal update flag only triggers correctly with a clean install of the latest build. Hope this helps anyone else hitting this roadblock!
Let me know in the comments if this worked for you or if you're seeing any other issues with the 3.1 Pro integration.
