Google folded Antigravity into the same Google AI subscription ladder that already prices Gemini’s chat app, Search features, and NotebookLM, so what you pay for Antigravity depends on which Google AI plan you’re on rather than a dedicated Antigravity bill.
The free tier, labeled Individual on Antigravity’s own pricing page, costs nothing and needs no credit card. It gives you the core agent model lineup — Gemini 3.1 Pro, Gemini 3.5 Flash, and other Gemini Enterprise Agent Platform models — unlimited Tab completions, and full access to the CLI and Scheduled Tasks. The catch is the quota: Google describes it as a “meaningful” allowance that refreshes weekly, correlated with how much work each prompt actually triggers rather than a flat per-day request count. A quick single-file edit and a multi-step refactor draw down that weekly budget very differently, so don’t expect a clean “X requests per day” number to plan around — Google’s own docs don’t publish one.
Paying unlocks a materially different refresh model, not just more of the same. Google AI Pro is $19.99/mo and moves Antigravity onto a 5-hour refresh cycle instead of a weekly one, with a higher ceiling before you hit the weekly cap underneath it. Google AI Ultra comes in two tiers — $99.99/mo for the 5x allowance and $199.99/mo for 20x — and both add access to third-party models inside Antigravity on top of Google’s own, plus the highest quota Google offers, still refreshed every 5 hours. None of these tiers are Antigravity-specific purchases; you’re buying a Google AI subscription that happens to raise Antigravity’s ceiling as one of many benefits alongside Gemini chat limits, NotebookLM capacity, and Google One storage (5 TB on Pro, up to 30 TB on Ultra 20x). If coding agent quota is the only thing you care about, the sticker price still buys a lot of things you may not use.
There’s also a cheaper middle option worth knowing about: Google AI Plus at $4.99/mo. Google’s own plan-comparison table lists it as carrying a “Limited” Antigravity agent-request allowance, one step above free but well below Pro. Google doesn’t market Plus as a coding plan — its listed benefits center on storage and general Gemini features — so treat the Antigravity access at that tier as a minor perk, not a serious upgrade path for daily agentic coding.
Once you exhaust your baseline quota on a paid plan, Antigravity doesn’t just cut you off. Pro and Ultra subscribers can burn through purchased AI credits (or promotional ones) for overage usage, billed at standard Gemini Enterprise Agent Platform consumption rates. A setting called “AI Credit Overages” controls whether that happens automatically — set to Never, Antigravity waits for your baseline quota to refresh rather than spending credits; set to Always, it draws on credits the moment the baseline runs out and switches back once the refresh lands. That’s a meaningfully different design from a hard usage wall: heavy users on Pro or Ultra can keep working past the included quota as long as they’re willing to pay incremental credit costs, rather than being forced into a plan upgrade the moment they hit a ceiling.
Two things Antigravity explicitly doesn’t support yet, according to Google’s own docs: there’s no bring-your-own-key or bring-your-own-endpoint option for extra rate limits, and there’s no organizational tier sold through a direct contract outside the Google Cloud path. Teams that need Antigravity under a business agreement go through the Organization plan instead, which runs on Google Cloud Terms of Service with project-level integration and consumption-based API pricing rather than a flat per-seat number — the kind of custom pricing you settle in a sales conversation, not on the public pricing page.
Antigravity’s arrival isn’t incidental to Gemini CLI’s story — it’s the direct replacement. On June 18, 2026, Google shut down Gemini CLI and the Gemini Code Assist IDE extensions for consumer accounts on the free, Pro, and Ultra tiers, pointing everyone still on those plans to Antigravity CLI and Antigravity instead. Only Gemini Code Assist Standard and Enterprise licenses managed through Google Cloud kept running on the old product. If you were using Gemini CLI for free before that date, Antigravity’s Individual tier is where you land now, with the same weekly-refresh tradeoff that defined Gemini CLI’s own free usage before the switch.
