| Free tier | users not on Google AI Pro or Ultra receive 'a meaningful quota, refreshed weekly' and 'a weekly rate limit'; the pricing page lists the plan without a subscription with 'Basic weekly rate limits'. No number is published, and the unit is a weekly share of agent work: the rate limits correlate with 'the amount of work done by the agent' unit mixed; metered on unstated; the plans and pricing pages state no number. 'Meaningful' is a discretionary allowance, which is harder to design against than a published quota. The free plan's reasoning models are Gemini 3.8 Flash, plus Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b, which the models page marks 'Will be removed on November 2, 2026'; Gemini 4 Argon and the Claude 5.5 models are not on the free plan |
|---|---|
| Price | none stated |
| Limits |
no numeric quota is published. The page states that rate limits 'correlate with the amount of work done by the agent' and are 'subject to modification'. The CLI's /usage panel (alias /quota) shows 'remaining requests/tokens for each supported model', and a standalone agy -p /usage run returns it as a text report |
| Binding | request-rate the unpublished weekly agent quota binds; there is no number to design against, which is why the row is a caveat rather than a recommendation |
| Identity | email a personal Google account on any plan, the free one included; a Google Workspace account signs in only after its administrator provisions Antigravity. Second gates: the account holder must be 18 or older, and the account must be associated with a country or territory where Antigravity is available. An account whose age Google holds unverified is verified with a government ID or a credit card authorization (not a charge), with other options in some regions |
| Egress | not applicable |
| Interface | cli the agy CLI, the Antigravity App and IDE extensions; model access follows the Google AI plan. Headless runs use credentials cached by one interactive agy sign-in; in a non-interactive environment with no terminal, a run that is not signed in exits with an 'authentication required' error instead of hanging. The vendor changelog lists a fix for print mode output lost in non-TTY runs on Windows (version 1.0.15) and a fix for the print mode hang in a script or subprocess (version 1.1.1) |
| Tooling | Antigravity App, IDE extensions and the agy CLI. agy -p PROMPT (aliases --print, --prompt) is a headless mode intended for direct scripting and CI: it sends one prompt, writes the response to stdout and exits; --output-format selects text, one JSON object or NDJSON events, --json-schema constrains the answer, and --input-format stream-json keeps one process for many turns fed on stdin |
| Composes with | the free surface of a Google AI plan, not a separate product. With modelProvider: gemini and GEMINI_API_KEY the CLI sends model requests directly to the Gemini API and holds no account session, so a key of inference/google-gemini-api drives the same headless mode, metered by the Gemini API for that key rather than by the account's plan |
| Reliability | the allowance moves with capacity: baseline rate limits are 'primarily determined by available capacity', and usage limits are 'subject to modification'; reaching the service through third-party software can end in suspension or termination of the account. The vendor's CLI tracker holds open issue 1313. It reports that a headless print mode run writes its full result and then never exits for some prompts, on versions 1.4.4 to 1.4.11 |
| Notes | The plans page is first-party for the shape of the quota and silent on its size; a comparison table that prints a number for this provider is quoting an aggregator. Gemini models share one limit 'drawn down according to API pricing', and non-Gemini models stay on a separate fixed limit |
| Evidence note | documented the quota structure and the headless mode are documented on first-party pages; no quota number is. A number needs a signed-in account reading /usage before and after a fixed workload, so the rung cannot rise without one |
