Google Antigravity limits: Free, Google AI Pro and Ultra
Data as of · Rows checked on vendor pages · Page updated
Short answer (as of 31 Oct 2026): Google Antigravity is free to use with a weekly quota, and Google AI plans raise the limits. Google AI Pro is $19.99 a month, with a quota refreshed every five hours until a weekly limit is reached. Google AI Ultra is $99.99 for 5x Pro’s rate limit in tokens, or $199.99 for 20x.
Google does not publish the quota sizes. Gemini models share one pool drawn down at API pricing; Claude and GPT models have a separate fixed limit. Past the limits, Pro and Ultra can use purchased AI credits. No moderated usage reports are published yet.

Key numbers
- Free is $0: basic weekly rate limits, unlimited Tab completions and Command requests. Google AI Plus gets the same Antigravity model access as Free (antigravity.google, checked 31 Oct 2026).
- Google AI Pro is $19.99 a month: a higher weekly limit than Free, Gemini 4 Argon, and Claude Sonnet 5.5 and Opus 5.5 on non-trial Pro subscriptions only.
- Google AI Ultra is $99.99 a month for 5x Google AI Pro’s rate limit in tokens, or $199.99 for 20x, per gemini.google/subscriptions. Google’s Antigravity plan docs describe Ultra as one tier and do not separate the two.
- Gemini models share one pool, drawn down at API pricing. Claude and GPT models sit on a separate fixed limit. Google’s models page shows a weekly and a five-hour meter for each.
- Past the limits, Google AI Pro and Ultra can use purchased AI credits from Google One, consumed at standard Gemini Enterprise consumption pricing when AI Credit Overages is set to Always. Bundle prices sit behind sign-in, and credits are not sold in Japan. Free has no overage.

How the Antigravity quotas reset
Google’s plan docs, checked 31 Oct 2026: Google AI Ultra gets “the highest, most generous quota, refreshed every five hours” and the highest weekly limits. Google AI Pro gets “a high, generous quota, refreshed every five hours until the weekly limit is reached”. Other users get “a meaningful quota, refreshed weekly”. Limits track the work the agent does, not the number of prompts, and Google does not publish the sizes.
Gemini 4 Argon on Google AI Pro
Google’s models page marks Gemini 4 Argon as available with paid Google AI Pro plans, or on trial with eligible premium devices (checked 31 Oct 2026). A post from @antigravity on X (16 Oct 2026 SGT) says Pro gets “a separate weekly-only Argon quota” on top of the existing Gemini bucket. No Google page says so, so PlanYield keeps that part labelled as a vendor post on X, read from a search-result title because x.com could not be opened. See the 16 Oct 2026 entry.
Coming up
Coming up, : Claude Sonnet 4.6 (thinking), Claude Opus 4.6 (thinking) and GPT-OSS-120b 'Will be removed on November 2, 2026'. Free and Google AI Plus are then left with Gemini 3.8 Flash only; Pro and Ultra keep Claude Sonnet / Opus 5.5. Source: antigravity.google (Vendor page).
