Antigravity standalone IDE blocks Gemini 4 Argon even for paid Pro
A footnote in Google's Antigravity docs says Gemini 4 Argon is unavailable in the standalone IDE, directing paid Pro users to the desktop app, agy CLI or VS Code extension.

Hidden catch in Google's Antigravity docs today: Even if you pay $20/mo directly for Google AI Pro, Gemini 4 Argon is blocked inside the standalone Antigravity IDE. Footnote *** on the official Models page reads: "Not available in Antigravity IDE. Available in the Antigravity App, Antigravity CLI, and IDE extensions." If you're on a paid Pro plan and still don't see Argon, stop opening the standalone Antigravity IDE, switch to the Antigravity 2.0 Desktop App (v2.23.1), agy CLI (v1.3.5), or the VS Code extension.
