Pro subscribers find Gemini 4 Argon locked behind Ultra in Antigravity
A Pro subscriber says Argon is locked behind an Ultra plan in Antigravity rather than rate-limited, and that 3.7 Flash and 3.1 Pro have been removed, calling Google's approach unfair to Pro users.

Opened Antigravity today after hearing Argon is finally here. I am subscribed to Pro plan, so I expected it would be accessible to some extent. But when I checked models, Argon is locked, not rate-limited, behind an Ultra plan and 3.7 Flash and 3.1 Pro are gone for good on top of that. I know argon is available for Pro Users in Gemini app. However, I am interested in an AI coding agent, not an ai chatbot. In all honesty what @google did is a greedy swindle and PR has to handle it ASAP before backlash grows.
