Seven reasoning models are selectable in the picker: Gemini 3.7 Flash, 3.6 Flash and 3.5 Flash; Gemini 3.1 Pro; Claude Sonnet 4.6 (thinking) and Claude Opus 4.6 (thinking); and GPT-OSS-120b. A separate model, Nano Banana 2, is not in the picker — the agent calls it when it needs a UI mockup, images for a page, or an architecture diagram.

Not straightforwardly, and the answer has changed. At launch in November 2025 Google described it as available “in public preview, at no cost for individuals”. Since the May 2026 plan restructure, quota is tied to Google AI plans: without one you get what Google calls a meaningful quota refreshed weekly; Google AI Pro at $20 a month raises it; Google AI Ultra at $100 and $200 a month multiply the Pro limit by five and twenty. The editor is not what you are paying for — rate limit is.

Completion predicts the next few characters. Antigravity is built around handing over a whole task: the agent plans, edits, runs terminal commands and drives a browser, then hands back artifacts — an implementation plan, a task list, screenshots, a browser recording — as the thing you review. Google's own framing is operating at a higher, task-oriented level. Tab completion is still there; it is just no longer the point.

They are the deliverables the agent produces instead of a raw log: task lists, implementation plans, screenshots and browser recordings. You can leave comments on any artifact to steer the next pass. The practical effect is that reviewing an agent's work stops being a matter of scrolling a transcript.

Opening a project points the agent at a local folder or git repository — the files stay where they are. What is sent to a model, and under what terms, is governed by Google's own privacy and enterprise documentation, not by this site, and it differs between the consumer plans and the Gemini Enterprise Agent Platform. Read Google's terms for your own plan; we will not paraphrase them for you, because getting that wrong would be worse than not answering.

No. Google's plans documentation states there is currently no support for bring-your-own-key arrangements, and no organisational contract tier. Enterprise customers go through the Gemini Enterprise Agent Platform instead.

macOS 12 (Monterey) or newer on Apple Silicon and Intel; Windows 10 64-bit or newer on x64 and ARM64; and Linux on x64 and ARM64 with glibc 2.28 and glibcxx 3.4.25 or newer, which covers Ubuntu 20, Debian 10, Fedora 36 and RHEL 8.

It is a heavily modified fork of Visual Studio Code. There is an open question — noted on Wikipedia — about whether it forks VS Code directly or forks Windsurf, which is itself a VS Code fork. Google has not settled it publicly, so neither will we.

On Google's own published comparison, 65.3% against 49.0% on DeepSWE v1.1, and 43.6% against 34.4% on FrontierCode 1.1 Main. Google also reports 1588 Elo on WebDev Arena for 3.7, with no paired 3.6 figure. These are the vendor's numbers for the vendor's model. The second pair is the one to sit with: both cuts fail more FrontierCode tasks than they finish.
