Is Google Antigravity Free? What the Free Tier, Students and AI Pro Actually Get

Free plan checked Oct 28, 2026 on Antigravity’s pricing page; quota rules Oct 25, 2026 on the plans docs; Google AI plan prices and Antigravity labels Oct 29, 2026 on Google’s AI plans page; student offer Oct 29, 2026 on Google One Help.

Short answer

Is Antigravity free? Yes. As of Oct 28, 2026, Google’s individual plan is “$0/month” with “Unlimited Tab completions”, “Unlimited Command requests” and “Basic weekly rate limits” on agent work. The catch: Google publishes no number for that weekly limit. Students and Google AI Pro ($19.99/mo) get more.

• Free: yes, $0, no subscription, with a weekly rate limit that has no published number.
• Unlimited: only Tab completions and Command requests. Agent usage is capped.
• Students: US college students 18+ can get Google AI Pro on a 12-month trial, card required, then $19.99/mo unless you cancel. Outside the US, Google lists a separate student bundle with no price on the help page.
• Google AI Plus ($4.99/mo): Google now labels its Antigravity agent requests “Limited”, next to Pro’s “Expanded”. Still no number.
• When to pay: if you hit the weekly wall often, or want Gemini 4 Argon or Claude 5.5 models, Google AI Pro at $19.99/mo (or $199.99 a year) is the step up.

Full plan-by-plan table: Antigravity pricing.

We haven’t tested Antigravity. Everything here is from Google’s own pages, quoted and dated.

What the free tier includes

Google’s plans docs list a baseline that every plan gets (verified Oct 25, 2026):

• “Use of Gemini models, including Gemini 3.8 Flash and other offered Gemini Enterprise models as the core agent model”
• “Unlimited Tab completions”
• “Access to all product features, such as scheduled tasks and the CLI”

For anyone not on Google AI Pro or Ultra, the quota is described as “A meaningful quota, refreshed weekly” and “A weekly rate limit”. The pricing card calls the same thing “Basic weekly rate limits” (re-checked Oct 28, 2026). So depending on which Google page you read, your quota is either meaningful or basic. Ya basic, as The Good Place would put it. Neither page puts a number on it.

The docs do explain why there’s no number: “the rate limits correlate with the amount of work done by the agent”, so “you receive more prompts when your tasks are straightforward”, while “more complex tasks consume more quota.” They also say “Usage limits for this service are subject to modification.” Fair enough as engineering. As a buyer, it’s frustrating: you can’t plan a week of work around a quota Google won’t size.

Platforms: “Available on macOS, Windows, Linux, and Googlebook”, and the homepage says “Available at no charge” (verified Oct 21, 2026).

Free models, and the November 2 cut

Per Antigravity’s models docs (verified Oct 26, 2026), the “Free & Google AI Plus” column has four reasoning models: Gemini 3.8 Flash, Claude Sonnet 4.6 (thinking), Claude Opus 4.6 (thinking) and GPT-OSS-120b. The last three are marked for removal on November 2, 2026.

So after November 2, the free tier keeps Gemini 3.8 Flash and loses Claude and GPT-OSS. That’s the real story for free users. The price stays $0, but the model list goes from four to one. If you’ve been using Antigravity’s free tier mainly for Claude Opus, that ends November 2.

Is Antigravity free for students?

Not as an Antigravity plan. US college students 18+ can get Google AI Pro, which Google One Help now calls “the 12-month trial”, and Antigravity takes its limits from that plan; students elsewhere get a separate “Google AI Pro with YouTube Premium Student bundle” whose price isn’t on the help page (verified Oct 29, 2026). The “trial” label matters, because Antigravity reserves Claude 5.5 on Pro for “non-trial subscriptions only”. Eligibility, steps and the fine print: Antigravity student discount.

Free vs Plus vs Pro vs Ultra

Plan	Price	Agent label	Models
Free	$0	Basic weekly	3.8 Flash; 3 more until Nov 2
AI Plus	$4.99/mo	Limited	Same as Free
AI Pro	$19.99/mo or $199.99/yr	Expanded	Adds Argon, Claude 5.5*
AI Ultra	$99.99 or $199.99/mo	Higher / Highest	Argon, Claude 5.5, 3P

Prices and the “Agent requests” labels (Limited, Expanded, Higher, Highest) are from Google’s AI plans page: Pro’s $199.99 annual price checked Oct 29, 2026, Plus’s $4.99 Oct 28, 2026; Ultra is “billed monthly only”. Free’s “Basic weekly rate limits” is from the pricing card (Oct 28, 2026). Models from the models docs (Oct 26, 2026).

*Pro’s Claude 5.5 models are “non-trial subscriptions only”; Argon is for “paid Google AI Pro plans or on trial with eligible premium devices” (verified Oct 26, 2026).

How the quota behaves on each tier, per the plans docs (verified Oct 25, 2026): Free and Plus get “A meaningful quota, refreshed weekly”. Pro gets “A high, generous quota, refreshed every five hours until the weekly limit is reached”. Google’s subscription page uses the same five-hour wording for Pro and adds “You can extend your limits by purchasing AI credits” (verified Oct 29, 2026).

Two more Pro and Ultra perks from the plans docs: they “can use purchased AI credits (or any one-time promotional credits) for additional overage usage above the baseline quota”, with an “AI Credit Overages” setting of Never or Always. And no plan supports “Bring-your-own-key (BYOK)” for extra limits (verified Oct 25, 2026). Google doesn’t publish the price of AI credits.

Does Google One include Antigravity?

Not as a separate perk. Antigravity’s plans docs describe one quota for everyone “not on Google AI Pro or Ultra”: “A meaningful quota, refreshed weekly” (verified Oct 25, 2026).

Google AI Plus used to be pure fog. Now there’s a label, at least. Google’s AI plans page rates Plus’s Antigravity agent requests “Limited” against Pro’s “Expanded” (verified Oct 29, 2026), while the models docs still put Plus in the same column as Free. So Plus may get a bit more than Free, but on Free’s models, and with no number attached to either. “Limited” is doing a lot of work for a $4.99 line item. I still wouldn’t buy Plus for Antigravity alone; see Antigravity Plus vs Pro.

When free stops being enough

You’ll know. Antigravity’s interface shows “Weekly Limit Remaining” and “Five Hour Limit Remaining” meters, plus a separate meter for “Claude and GPT models” (models docs, verified Oct 26, 2026). On Free, the quota is “refreshed weekly”, and overage credits are only on Pro and Ultra, so an empty meter means waiting. How the meters reset: Antigravity usage limits.

Signs it’s time to pay:

• You hit the weekly cap mid-week, more than once.
• You need Claude after November 2, when the free tier loses it.
• You want Gemini 4 Argon, which isn’t on Free at all.

Also, if you’re here from Gemini CLI: Google says that from June 18, 2026 you “can no longer use the Login with Google option” for Gemini CLI on the individual, AI Pro and AI Ultra tiers, and points people to “the Antigravity family of products” (codeassist.google, verified Oct 29, 2026). The CLI is part of Antigravity’s baseline on every plan. Details: Gemini CLI vs Claude Code.

Here’s what I’d do

Start on Free. It’s genuinely $0 with no subscription, and a week of real work tells you more about that unsized quota than any page Google has published. If you use Claude in Antigravity, do it before November 2.

If you’re a US college student, claim the AI Pro trial, but set a calendar reminder before it renews at $19.99. Assume the Claude 5.5 models may not appear until you see them in your own model picker. Is a “free student plan” a plan or a trial? Google’s pages call it both, which is the most Ross-and-Rachel “we were on a break” situation in software pricing: the answer depends on which page you ask, and it matters.

If you keep hitting the weekly wall and you’re not a student, Google AI Pro at $19.99 a month is the obvious next step. If you’re sure you’ll stay a year, $199.99 annual is cheaper than twelve monthly payments ($239.88). Weighing the top tier instead? Google AI Pro vs Ultra. Comparing with other tools first? Antigravity vs Cursor, Is Cursor free? and AI coding tools compared.

Deciding between Google’s $19.99 plan and Anthropic’s $20 one? See Google AI Pro vs Claude Pro for coding.

If Antigravity stops with “Individual quota reached”, what that Antigravity error means covers the reset and whether a paid plan helps.

Agent runs stopping early on the free tier? Antigravity “Agent execution terminated due to error” helps you tell quota from other causes.

If Antigravity won’t let you in at all, the Antigravity verification required fix covers the eligibility checks.

Free-tier blockers are one thing; a 400 location or INVALID_ARGUMENT error is another — Antigravity Error 400.
