So if you're on Google AI Pro, you can chat with Argon all day in the Gemini app. You just can't code with it in Antigravity. That one's Ultra only. Google's best coding model, locked out of Google's own coding tool unless you pay for the top plan. Developers on the API get it everywhere though. it's really funny how that works.
