Antigravity credits calculator and lockout planner

The lockout planner

Two limits stack on paid plans: a five-hour sprint quota and a weekly ceiling. The mechanic is first-party; the units below are community-measured on Pro (about 250 units per five hours, weekly ceiling near 2,800), because Google publishes none.

Community-derived estimate, not a quote: quota units, the heavy-model multiplier (8x), and per-prompt dollar rates are forum-measured and Google has changed limits at least twice since launch. Ultra ceilings combine the community Pro baseline with Google's stated 5X/20X multipliers. The five-hour sprint cap can also bite intraday; the weekly ceiling is the one that locks you out for days.

What a dollar of subscription buys, per tier

Google states quota only relatively: Ultra $100 buys 5X of Pro, Ultra $200 buys 20X. Dividing price by multiple is first-party arithmetic, and it shows the $100 tier carries no quota discount at all:

As read on 2026-10-12, the per-tier list lives on one first-party page: antigravity.google/docs/models, which the plans documentation links to with "Refer to Models for a breakdown of model availability." Its table (columns "Free & Google AI Plus", "Google AI Pro", "Google AI Ultra", "Enterprise") marks Claude Sonnet 5.5 (thinking) and Claude Opus 5.5 (thinking) available on Google AI Pro, Google AI Ultra and Enterprise but not on Free & Google AI Plus, with the Pro access footnoted "Available on Google AI Pro for non-trial subscriptions only." It marks Claude Sonnet 4.6 (thinking) and Claude Opus 4.6 (thinking) available on Free & Google AI Plus and Google AI Pro only, no longer on Google AI Ultra or Enterprise, and GPT-OSS-120b available on Free & Google AI Plus, Google AI Pro and Google AI Ultra but not Enterprise. All three of those older models are footnoted "Will be removed on November 2, 2026." So every tier, Enterprise included, has some third-party model today, but no tier has all of them, and after 2026-11-02 the table leaves Free & Google AI Plus with Gemini models only. The plans documentation still lists "Access to third-party models" under "Users on Google AI Ultra receive the following benefits:", without splitting the 5X and 20X tiers, which understates what the models table shows for Pro and Free. The pricing page no longer names models: its $0 card reads "Access to a variety of agent models", linking to /docs/models, and its paid cards open with "Everything in Individual and:" and "Everything in Pro and:". Through 2026-09-28 that $0 card read "Agent model: access to Gemini 3.8 Flash, Gemini 3.7 Flash, Gemini 3.6 Flash, Gemini 3.1 Pro, Claude Sonnet & Opus 4.6, gpt-oss-120b", and on 2026-09-28 the models table put Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b on every individual tier and no third-party model on Enterprise. The models page meters "Claude and GPT models" on their own weekly and five-hour limits, separate from Gemini models. Full comparison: Pro vs Ultra quota.

Credit packs

Google's help pages give pack sizes, as examples rather than a full list; pack prices they do not give at all. The prices below are press and community reported, implying roughly $1.00 per 100 credits:

The flat structure is the finding: assembling 20,000 credits from 2,500-packs costs $199.92 versus $199.00 for the big pack, a bulk saving of $0.92. Credits are overage-only above plan quota. More: what one Antigravity credit costs.

What Google does not publish

Checked across Google's Antigravity docs, blog, and help pages on 2026-10-12:

• credit-per-token rate
• credit-per-request rate
• per-model credit multipliers
• numeric plan quotas for any tier
• an Antigravity-specific credit allotment per plan
• top-up pack prices on public pages
• credit expiry period
• weekly-lockout duration
• the quota-to-credits exchange rate

Google's own help page confirms that "the amount of AI credits used for each feature and model varies" without quantifying it. Everything above this list is computed from what IS published; everything community-measured is labeled.

Using Antigravity at a company

There is no Antigravity organization subscription with a quota multiple to rank against Pro. Google's pricing page lists a Business plan that reaches Antigravity and the CLI through Google Cloud three ways: API access billed on consumption, a pay-as-you-go plan with a $0 seat fee, and, for eligible Gemini Enterprise customers, Standard/Plus seats starting at $30 USD per seat per month. First seen on 2026-08-03.

Worth knowing before you plan around it: as read on 2026-10-12, the contradiction sits inside one page. The Antigravity plans documentation opens by saying Antigravity is available to teams under Google Cloud terms in Gemini Enterprise, the same route the pricing page advertises, and further down the same page still lists organizational tiers through a custom contract under what is not supported. The consistent reading is that access through Google Cloud exists and custom contract tiers do not.

FAQ

How much does one Antigravity credit cost?

Google does not publish a credit price on any public page. Its help page gives 2,500, 5,000 and 20,000 credits as example pack sizes, and says credits are offered in various increments; the prices reported by press and community sources ($24.99, $49.99, $199) imply roughly one cent per credit. Prices appear only inside the authenticated purchase flow.

How does the Antigravity weekly lockout work?

Two limits stack: quota refreshes every five hours until a weekly ceiling is reached; hitting the ceiling locks you out until the weekly reset regardless of five-hour refreshes. The mechanic is documented by Google; the numeric limits are not, and community measurements put the Pro sprint at about 250 units per five hours with a weekly ceiling near 2,800.

Do Antigravity plans include AI credits?

Google publishes no Antigravity-specific credit allotment for any plan. Its Antigravity docs meter plans in compute quota and describe AI credits, purchased or one-time promotional, as cover for overage above that quota, consumed at Gemini Enterprise consumption pricing. The Antigravity pricing page does list a "Flexible AI credit pool" on the Pro and Ultra cards, without saying what is in it.

Is Google AI Ultra worth it for Antigravity quota?

The $100 Ultra tier carries no quota discount: $99.99 buys 5X of Pro quota, which works out to $20.00 per quota unit against the $19.99 Pro itself charges. Only the $200 tier prices quota below Pro, at $10.00 per unit, half the Pro rate. Third-party model access is not what separates them: Google lists it for Google AI Ultra as a whole.
