Gemini 3.1 Pro is not available on this version. Please upgrade to the latest version
不是这个问题时 / 边界
You're already on the latest build, or the message is about quota rather than version.
根因
The installed Antigravity build is older than the one that supports the new model.
修复步骤
- Download the latest installer from the official Antigravity site and run it over your current install. Don't uninstall first; the accepted answer says settings were kept.
- On Linux with the apt repo, upgrade through apt (one user confirmed).
如何验证
The model can be selected and replies.
