Google Antigravity Pricing (2026): Free, Plus, Pro and Ultra
Antigravity is $0 to start, and US college students can get Google AI Pro free for a year. What Plus, Pro and Ultra add in models and limits, dated and sourced.

Models and limit meters checked Oct 26, 2026 in Antigravity’s models docs; plan quotas checked Oct 25, 2026 in Antigravity’s plans docs; plan cards checked Oct 25, 2026 on Antigravity’s pricing page. Google AI plan prices checked Oct 20, 2026 on gemini.google. Other dates are under Sources. This page has no affiliate links (how we work).
You don’t pay Antigravity directly. It’s $0 to start, and after that your models and rate limits come from whichever Google AI plan you have: Plus ($4.99), Pro ($19.99) or Ultra ($99.99 or $199.99). The money question is Pro, because that’s where Gemini 4 Argon and Claude 5.5 show up. And on November 2, 2026, three models leave the Free and Plus list, so the free tier gets thinner next week.
We haven’t tested Antigravity. Everything below comes from Google’s own pages and docs.
Quick answer (Oct 26, 2026)
- Trying it: Free, $0. Details in Is Antigravity free?
- Google AI Plus ($4.99): same models as Free in the docs. Not worth buying for Antigravity alone.
- Google AI Pro ($19.99): adds Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5, plus a five-hour refresh on your quota. The Claude models need a paid, non-trial subscription; Argon now also works on some trials.
- All-day agents: Google AI Ultra, $99.99 (“5x higher usage limits vs. AI Pro”) or $199.99 (“20x”).
- Comparing: Antigravity vs Cursor, Google AI Pro vs Claude Pro, or the field in AI coding tools compared.

Sources: Antigravity pricing (cards Oct 25, 2026; business Oct 22, 2026), models docs (Oct 26, 2026), plans docs (Oct 25, 2026), Google AI plans (prices Oct 20, 2026). “5x” and “20x” are Google’s wording for Google AI usage overall; no Antigravity number is published.
No annual Google AI Pro price is published (checked Oct 21, 2026). Outside the US, check current price on gemini.google for your region. Antigravity runs on “macOS, Windows, Linux, and Googlebook” (antigravity.google, checked Oct 21, 2026).
“Free & Google AI Plus” share one column: what that means
In the models docs (checked Oct 26, 2026), Free and Google AI Plus are literally one column. Same models. And the plans docs (checked Oct 25, 2026) put Plus in the bucket of “Users not on Google AI Pro or Ultra plans”, who get “A meaningful quota, refreshed weekly” and “A weekly rate limit”. Google AI’s Plus card on gemini.google has no Antigravity line at all (checked Oct 21, 2026).
The one hint Plus gets anything extra is the overview docs: “upgrade to Google AI Plus, Pro, or Ultra for higher rate limits and optional AI credit overages” (overview, checked Oct 21, 2026). But the plans docs say only “Users on Google AI Pro or Ultra plans can use purchased AI credits”. Google’s two docs pages don’t agree on Plus, and neither puts a number on it.
So “does Google AI Plus include Antigravity?” Yes, in the sense that everyone gets Antigravity. Paying $4.99 for it buys you, by Google’s own published wording, roughly nothing you can measure.
If all you want is the yes/no on cost, plus what students get, that’s answered in Is Antigravity free?
Plus costs $4.99 for Free’s model list and a limit Google won’t quantify, and after November 2 that list is one Flash model. Charging for a tier and then emptying it is a sad way to treat the people who paid first.
Google AI Pro and Ultra: limits, AI credits and Argon
Limits, as worded. Pricing cards: Free “Basic weekly rate limits”, Pro “More rate limits”, Ultra “Even more rate limits” (pricing, checked Oct 25, 2026). Plans docs: Pro gets “A high, generous quota, refreshed every five hours until the weekly limit is reached” and “A higher weekly rate limit”; Ultra gets “The highest, most generous quota, refreshed every five hours”, “The highest weekly rate limits” and “Access to third-party models”. Also: “more complex tasks consume more quota” (plans docs, checked Oct 25, 2026). The app shows “Weekly Limit Remaining” and “Five Hour Limit Remaining” meters, one for Gemini models and one for “Claude and GPT models” (models docs, checked Oct 26, 2026). Google AI Pro’s own card calls it “Entry rate limits to agent model in Google Antigravity” (gemini.google, checked Oct 21, 2026). Numeric limits: not published.
AI credit pool. Pro and Ultra cards list a “Flexible AI credit pool”. When you run out, Pro and Ultra users can spend purchased AI credits, with an “AI Credit Overages” setting of Never or Always. There’s no bring-your-own-key option (plans docs, checked Oct 25, 2026). The AI credit price isn’t in our notes, so check current price.
Models on Pro. From the models docs, checked Oct 26, 2026:
| Model | Free & Plus | Pro | Ultra |
|---|---|---|---|
| Gemini 3.8 Flash | Yes | Yes | Yes |
| Gemini 4 Argon | No | Yes† | Yes |
| Claude Sonnet 5.5 | No | Yes* | Yes |
| Claude Opus 5.5 | No | Yes* | Yes |
| Claude Sonnet 4.6 | Until Nov 2 | Until Nov 2 | No |
| Claude Opus 4.6 | Until Nov 2 | Until Nov 2 | No |
| GPT-OSS-120b | Until Nov 2 | Until Nov 2 | Until Nov 2 |
† “Available with paid Google AI Pro plans or on trial with eligible premium devices.” * “Available on Google AI Pro for non-trial subscriptions only. To cancel your trial and switch to a paid Google AI Pro plan, submit a request.” Enterprise also gets Gemini 3.7 Flash, 3.6 Flash and 3.1 Pro.
New since our Oct 22 version: Gemini 4 Argon is no longer non-trial only on Pro. Google’s docs now allow it “on trial with eligible premium devices”. The Claude 5.5 models are still non-trial only. Which devices count as “eligible premium devices” isn’t listed on that page.
Argon still has an odd home: “Not available in Antigravity IDE. Available in the Antigravity App, Antigravity CLI, and IDE extensions.” Google’s flagship model skips Google’s own editor.
Students. Google AI Pro is free for a year for “eligible U.S. college students ages 18+”, redeem “until December 31, 2026”, then “$19.99/month” unless cancelled (gemini.google/students, checked Oct 25, 2026). Google’s terms call it a “trial”, and the student page doesn’t mention Antigravity, so check your model picker for Claude 5.5.
Business. Two routes: Google Cloud API “with consumption-based pricing”, or Gemini Enterprise “Standard/Plus plans starting at $30 USD per seat per month” or a “Pay-as-you-go plan with $0 seat fee” (pricing, checked Oct 22, 2026).
November 2, 2026: the model removals and who they hit
The models docs mark Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b as “Will be removed on November 2, 2026” (checked Oct 26, 2026).
- Free and Plus: hit hardest. After Nov 2, the list is Gemini 3.8 Flash only. No Claude at all.
- Pro: loses the two Claude 4.6 models and GPT-OSS but keeps Claude Sonnet 5.5 and Opus 5.5 (non-trial) and Argon.
- Ultra: loses GPT-OSS-120b only; its column doesn’t list the Claude 4.6 models.
If you’ve been using Claude Opus 4.6 on Free, this week is the time to decide whether Flash alone is enough, or whether Pro’s $19.99 is.
Antigravity CLI replaced Gemini CLI (June 18, 2026)
Google’s blog said: “On June 18, 2026, Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests for Google AI Pro and Ultra, as well as those using it free of charge using Gemini Code Assist for individuals”, with Antigravity CLI as the replacement (Google Developers Blog, checked Oct 20, 2026). The CLI has no separate price; it’s included on all plans (“Access to all product features, such as scheduled tasks and the CLI”, plans docs, checked Oct 25, 2026). Gemini Code Assist seats are unaffected and cost $22.80 or $54 per user a month, or $19 and $45 on annual commitment (codeassist.google, checked Oct 26, 2026). What’s left of the old free quota is in Gemini CLI free tier limits.
Here’s what I’d do
Use Free, and the Claude 4.6 models while they last. After November 2, judge Free on Gemini 3.8 Flash alone.
Skip Plus for Antigravity. Same models as Free, and Google’s own docs don’t agree on whether you get more.
Pay for Pro when you want Claude 5.5 or Argon. Use the App, CLI or IDE extensions for Argon. Watch the five-hour meter in week one, and leave AI Credit Overages on Never until you know your usage.
Students: claim the year, set a reminder. It auto-renews at $19.99.
