Questions, answered honestly
Including the ones where the honest answer is that Google has not published it. Sources and check dates are on every answer that has one.
Google's announcement names Gemini 3, Anthropic's Claude Sonnet and OpenAI GPT models, chosen per task rather than fixed for the whole workspace. Third-party coverage lists a longer and more specific set, including Gemini 3 Flash and open-weights GPT variants, but we cannot confirm those from a Google page. The model picker inside your own install is the only current answer that is definitely right.

A completion tool works inside the file you have open and finishes what you were typing. Antigravity's unit of work is a task: you describe an outcome, and the agent moves between the editor, the terminal and a browser to reach it, then hands back a plan, a walkthrough and often a browser recording.
The practical difference is where your attention goes. Completion keeps you in the code. This keeps you in review — which is a real skill change, and not everyone finds it an improvement.

It is free during the public preview. Rate limits refresh every five hours and are tied to how much work a request represents rather than a prompt count, so a single large refactor can consume more of the window than a dozen small questions.
Google has not published what happens when the preview ends. Anyone quoting a post-preview price, this site included, would be guessing.

That question is answered by Google's terms and privacy documentation for Antigravity, not by us, and the answer differs between personal accounts and Workspace or Cloud accounts. Read those before pointing an agent at anything confidential.
Two things are worth knowing regardless: the project folder set you choose at setup is the boundary of what agents can read, and New Worktree Mode keeps a run out of your working tree.

Google has not published a supported-language list, which is normal for an agent that works through a general editor, a shell and a browser rather than through per-language tooling. In practice the constraint is usually your project's build and test commands — an agent that can run your test suite can work in your language.
Through the knowledge base. Agents retrieve from it and write back to it — snippets and task sequences that worked — so later runs start from what earlier ones established rather than from nothing.
Google has not published how long that store is kept, where it lives, or how to clear it. If that matters to you, it is a question for Google support rather than for a guide.

No. There is one download location, antigravity.google/download, and every link here points at it. This site hosts no installer, no mirror and no “modified build”. Anything else offering one is not something we can vouch for.

Never. This site has no accounts, no checkout and no forms. It cannot take a payment because there is nothing here to buy. Do not enter a Google password, a card number or an API key on this site — there is no field that would legitimately ask for one.
Still unanswered? Google's official documentation is the authority, and we would rather send you there than guess. If you think an answer above is wrong, tell us.
