What it is
Gemini is Google's AI assistant. Google Antigravity is, in Google's words, "our agentic development platform, allowing anyone to build in the agent-first era"1. It comes as an app, a CLI, an IDE, and an SDK1.
My plan
I have one Google AI Ultra subscription on the $199.99-a-month tier, the one Google's pages call Ultra 20x2,3. As of November 5, 2026, Google lists Ultra at "Starting at: $99.99 / month," with $199.99 a month for the higher tier2. Google's Google One page names the two tiers Ultra 5x and Ultra 20x3.
Per Google's pages, Ultra includes the highest access to Gemini 4 Argon, Google Flow credits, higher agent rate limits in Antigravity, YouTube Premium (individual plan), Google Home Premium (Advanced), and Project Genie2. By tier, Google lists 20 TB of storage and 10,000 monthly Flow credits for Ultra 5x, and 30 TB and 25,000 credits for Ultra 20x3.
What it's good at
Google describes the Antigravity CLI as a way to "run autonomous coding agents, execute shell commands directly"1. The Antigravity IDE is "the fully-featured, agentic IDE"1. Antigravity has a free individual tier with basic weekly rate limits, and Google AI Ultra adds higher access to the latest Gemini models, more rate limits, and a flexible AI credit pool4.
The limits are in the rate limits and the tiers. Google's Antigravity pricing page names rate limits as the thing the paid tiers raise, and it doesn't publish a price for Ultra there4. Google's two pages also describe Gemini app usage a little differently: one says "up to 20x higher than the Pro plan," and the other says "5x higher usage limits in Gemini than the AI Pro plan"2,3.
What I use it for
Gemini and Antigravity for software engineering and research.
