The picker, the pools and the price

Seven reasoning models you can choose between, one image tool you cannot, and a quota system that meters Google's models separately from everyone else's.

The bench

Pick a model to read the profile Google publishes for it. Where Google publishes nothing, the row stays blank.

Nano Banana 2 is not in the picker. The agent reaches for it when it needs a mockup, images for a page, or an architecture diagram.

The picker

Two pools, metered separately.

Gemini usage and third-party usage draw down different allowances, each shown as a five-hour figure and a weekly one. Running Claude dry does not stop you working; it stops you working that way.

Access to third-party models sits on the Ultra tier according to Google's plans page. There is currently no support for bringing your own API key, and no organisational contract tier.

What it costs

Restructured on 19 May 2026. The top Ultra tier came down from $250 to $200 in the same change.

Quotas, not seats

You are not buying Antigravity. You are buying rate limit.

The editor itself is not the paid thing. What the plans buy is quota, drawn down as the agent works — and Google is explicit that the draw-down is “correlated with the amount of work done by the agent, which can differ from prompt to prompt”. A prompt count will not predict your bill.

In May 2026 Google folded Flash and Pro usage into a single shared limit, removed AI Credits from the base plans and raised the quotas to compensate. Credits now exist only as overage: the AI Credit Overages setting is either Never, meaning you wait for the refresh, or Always, meaning you spend credits automatically when the baseline runs out.

Prices change, and these did

Every figure on this page carries the date it was read from Google's own pages: 30 August 2026. Antigravity's pricing has already been restructured once and one model is on introductory pricing that doubles on 1 January 2027. Check antigravity.google/docs/plans before committing to a tier.

Where the facts come from

Everything on this site is checked against Google's own pages, and dated.

Antigravity changes quickly — models, quotas and prices have all moved since launch. Figures here carry the date they were checked. When they disagree with Google's documentation, Google's documentation is right and this page is stale; tell us and we will fix it.

Nothing is hosted here: we do not host software, mirror an installer, or ask for an account, licence key or payment. Downloads, sign-in and support all live on Google's own domain.
