Antigravity pricing: what each plan costs and gets you
Google Antigravity is free to start, with a weekly limit. More usage means a Google AI plan: Pro at $19.99 a month, or Ultra at $99.99 or $199.99 for 5x or 20x Pro's limit (US prices). Pro and Ultra refresh every five hours up to a weekly limit, and add Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5. Teams pay through Gemini Enterprise, from $30 a seat a month or pay-as-you-go.
Google publishes no request or token counts for any plan, so the limits below are the ones it states: refresh times, multiples and which models each plan can use.
Checked 3 November 2026 against Antigravity pricing, its plans documentation and Google AI plans · By Soren Starck
| Plan | Price a month | Rate limit | Quota refresh | Can buy AI credits |
|---|---|---|---|---|
| Free | $0 | Basic | Weekly | No |
| Google AI Plus | $4.99 | Not on Antigravity’s pricing page | Weekly | No |
| Google AI Pro | $19.99 | High (the base for Ultra’s 5x and 20x) | Every 5 hours, up to a weekly limit | Yes |
| Google AI Ultra | $99.99 | 5x Pro | Every 5 hours, up to a weekly limit | Yes |
| Google AI Ultra | $199.99 | 20x Pro | Every 5 hours, up to a weekly limit | Yes |
Is Antigravity free?
Yes, with a limit on the agent. The free plan has unlimited Tab completions and unlimited Command requests, plus what Google calls basic weekly rate limits for agent work. Its quota refreshes once a week, so a heavy day can leave you waiting days rather than hours. Google AI Plus at $4.99 sits in the same column of Google's model table, is not on Antigravity's pricing page and cannot buy AI credits, so it is not the plan to buy for Antigravity.
What do Pro and Ultra add?
Pro moves you from a weekly refresh to one every five hours, up to a weekly limit, and opens the better models. Google calls that the entry rate limit for the agent. Ultra keeps the five-hour refresh with higher weekly limits: Google sets the $99.99 tier at 5x Pro's tokens and the $199.99 tier at 20x, so the top tier costs twice as much for four times the limit.
All of these plans also cover the Gemini app and Google's other AI products, which what Gemini costs goes through. There is no plan that buys Antigravity alone.
Which models does each plan get?
| Model | Free and Plus | Pro | Ultra | Enterprise |
|---|---|---|---|---|
| Gemini 3.8 Flash | Yes | Yes | Yes | Yes |
| Gemini 4 Argon | No | Yes, paid plans and some trials | Yes | Yes |
| Claude Sonnet 5.5 (thinking) | No | Yes, not on trials | Yes | Yes |
| Claude Opus 5.5 (thinking) | No | Yes, not on trials | Yes | Yes |
| Gemini 3.7 Flash, 3.6 Flash, 3.1 Pro | No | No | No | Yes |
| Claude Sonnet 4.6 (thinking), until 18 Nov 2026 | Yes | Yes | No | No |
| Claude Opus 4.6 (thinking), until 18 Nov 2026 | Yes | Yes | No | No |
| GPT-OSS-120b, until 18 Nov 2026 | Yes | Yes | Yes | No |
A Pro trial gets Gemini 4 Argon only on eligible premium devices and does not get the Claude models. Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b are still listed, with a removal date of 18 November 2026 (Google's models page, read on 6 November 2026); after that, Free and AI Plus keep only Gemini 3.8 Flash.
How do the Antigravity limits work?
The limit measures the work the agent does, not the number of prompts, so a straightforward task costs less of it than a complex one. Gemini models share one limit, drawn down according to their API prices: a cheaper Flash model uses it more slowly than a Pro-class one. Claude and GPT models sit on a separate limit, and the usage view shows them as two meters, each with a five-hour and a weekly figure. Google adds that these limits can change.
What do AI credits cost?
AI credits pay for usage past your plan's quota, and only Pro and Ultra can buy them; they are not sold on Plus or in Japan. Google sells them through Google One in sizes such as 2,500, 5,000 or 20,000, with an optional auto-reload, and they may expire. Pack prices appear only once you are signed in there, so this page does not quote one.
Credits are spent at standard Gemini Enterprise consumption pricing, and the AI Credit Overages setting decides whether Antigravity uses them when your quota ends: Always or Never. For a sense of scale, the Gemini API price list has Gemini 4 Argon at $2 per million input tokens and $10 output through 30 November 2026, then $4 and $20, and Gemini 3.8 Flash at $0.75 and $3.75 through 31 December 2026, then $1.50 and $7.50.
What does Antigravity cost for teams?
Teams come in through Gemini Enterprise, for eligible customers: Standard and Plus plans from $30 per seat per month, or a pay-as-you-go plan with a $0 seat fee and consumption-based pricing. Enterprise is also the only plan with Gemini 3.7 Flash, 3.6 Flash and 3.1 Pro in the table above.
Which Antigravity plan should you pick?
Start on Free if you are trying it. Move to Pro at $19.99 when the weekly refresh stops you, or when you want Gemini 4 Argon or the Claude 5.5 models. Move to Ultra at $99.99 when Pro's limit stops you during the week, and to $199.99 only if 5x is not enough. If Claude is most of what you run, compare Claude Pro, Max and Ultra first, since Claude models sit on Antigravity's separate limit.
Seeing how much of your quota is left
Antigravity's Settings page shows your baseline quota across models when you stop to look. Every way to read it is in how to check Antigravity usage.
SessionWatcher keeps your Antigravity usage in the Mac menu bar or the Windows taskbar, so you see the limit coming before a task stops, and it shows the same reading for the other AI coding tools you use. It reads usage only, not your code or conversations.

Frequently asked questions
Is Google Antigravity free?
Yes, to start. Antigravity’s pricing page lists individuals at $0 a month with unlimited Tab completions, unlimited Command requests and basic weekly rate limits. Agent requests are what the limit stops, and the free quota refreshes weekly rather than every five hours.
How much is Antigravity Pro?
There is no separate Antigravity subscription. Pro is the Google AI Pro plan at $19.99 a month in the US, which also covers the Gemini app and Google’s other AI products. In Antigravity it adds a quota that refreshes every five hours until a weekly limit, Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5, and the option to buy AI credits.
What is the difference between the $99.99 and $199.99 Ultra plans?
The rate limit. Google sets the $99.99 tier at 5x Pro’s limit and the $199.99 tier at 20x, so the second costs twice as much for four times the limit. The Antigravity models are the same on both.
What happens when you run out of Antigravity quota?
On Free and Plus you wait for the weekly refresh. On Pro and Ultra you wait for the five-hour refresh or the weekly limit to reset, or buy AI credits and set AI Credit Overages to Always, which spends them once the baseline quota is gone. Set to Never, the agent stops at the limit instead.
How much does Antigravity cost for a team?
Teams buy it through Gemini Enterprise. Antigravity’s pricing page lists Standard and Plus plans from $30 per seat per month, and a pay-as-you-go plan with a $0 seat fee and consumption-based pricing, both for eligible Gemini Enterprise customers.
