Hi @Luke_Celitan,

Welcome to the Forum.

Thank you for reaching out.

Why Earlier Gemini Models Disappeared

Gemini 3.1 Pro, Gemini 3.6 Flash, and Gemini 3.7 Flash were retired from individual consumer plans as part of the transition to Gemini 3.8 Flash and Gemini 4 Argon (see our Models page). If you are running an older version of Antigravity—or if your client has a stale local model cache—the retired Gemini models disappear while the newer Gemini models do not populate until the app is updated and refreshed.

How to Restore Your Gemini Models

  1. Update to the Latest Release: Download and install the latest version of Antigravity from Download (or check for updates in the app; see the Changelog).
  2. Reset Your Session / Clear Cache:
    • Open the Command Palette (Ctrl+Shift+P on Windows/Linux or Cmd+Shift+P on macOS) and run Antigravity: Reset Onboarding, or sign out, clear your local application cache, and sign back in.
  3. Check Your Model Picker:
    • All Plans (Free, Google AI Plus, Pro, Ultra): You will see Gemini 3.8 Flash (Low, Medium, and High thinking).
    • Paid (Non-Trial) Google AI Pro & Google AI Ultra: You will also see Gemini 4 Argon (Medium and High thinking) in the Antigravity App, Antigravity CLI, and IDE extensions (note that Gemini 4 Argon is not available in the standalone Antigravity IDE; see the Models page).

If you still do not see any Gemini models after updating to the latest release and signing back in, please share your Antigravity version, operating system, subscription tier, and a screenshot of your model selector so we can take a closer look.
