Me too. I have a basic Google One account which is now called "Google AI Plus" and it says "Get 2x higher usage access than Free". The Google AI Pro plan says "Get 4x higher usage access than Free" (from https://gemini.google/subscriptions/).

I tried antigravity with Gemini 3.8 Flash High. I used a prompt similar to what I use with Codex and Claude Code and it used up my weekly quota in 10 minutes without stopping or giving me anything useful at all.

I have the $20 plan on Anthropic and OpenAI and frequently use up the five hour window but usually get at least 2-3 hours of useful work from similar prompts. The prompt was about an embedded firmware designing a bluetooth protocol for a gamepad (the firmware was already quite mature and this is not a large change).

I was super excited to sign up for the Pro plan and compare it until I read the limits so now I didn't even bother because I'm convinced it will be trash. And just for the record I see "Gemini 4 Argon" available in my antigravity install.
