Antigravity now lives inside the macOS Gemini app — behind an AI Ultra paywall

Antigravity now lives inside the macOS Gemini app — behind an AI Ultra paywall

What Google shipped on October 13

Google's availability post for Gemini 4 Argon confirms that Google Antigravity's agentic coding interface is now available directly in the Gemini macOS app. 9to5Google describes the entry point: a new Liquid Glass pill in the top-right corner of the window, with the same button serving as the exit, launching the full experience that previously existed only in the dedicated Antigravity application. Antigravity first shipped on November 18, 2025 alongside Gemini 3 and was relaunched as a standalone, agent-first IDE at version 2.0 during Google I/O 2026.

Google's reason: Argon simply codes better

Google's framing is deliberately narrow. Argon, the company writes, "brings major improvements in coding," so it is making it easier to switch between chatting and coding. SiliconANGLE reduced that to the practical effect: a chat can turn into a coding session without a jump to a separate tool. The demo rrtechpulse highlighted has Antigravity inside the Gemini macOS app converting a sketch of measurements and a photo of a couch into a 3D-printable sofa leg.

The paywall is the real story

Every report agrees on the tiers. Inside the Gemini app, Argon requires AI Pro or higher, while Antigravity itself requires AI Ultra. Ars Technica puts the prices at $20 a month for AI Pro and from $99 a month for AI Ultra; CloudZero's breakdown lists $19.99 Pro, $99.99 Ultra and $199.99 Ultra 20x. The Verge notes that Antigravity is only available in the Gemini app with an AI Ultra subscription, and the same restriction applies in the standalone Antigravity desktop app, the Antigravity CLI, AI Studio and Android Studio Canary. Free accounts are not on the list. For developers, the API introductory price is $2 per million input tokens and $10 per million output tokens until November 30, 2026, then $4 and $20, with cached input tokens at 95 percent off.

macOS only, and Windows goes unmentioned

digitBin points out that Google's desktop app page requires an Apple Silicon Mac running macOS Sequoia 15.0 or later. Google says the Windows version is getting more features but does not say whether the coding interface is one of them; SiliconANGLE stresses that Google did not mention a Windows version at all. Antigravity meanwhile continues as its own application on other platforms.

The rest of the update is a redesign

The same release reshapes the macOS client: a Chat/Task switcher that renames Gemini Spark to Task, a Scheduled view listing Spark tasks and scheduled actions, search moved to the top-right of the navigation panel, Skills invoked through @ mentions instead of slash commands, and Connected Apps renamed Connectors. Task mode keeps Gemini working "even when you're not at your computer" across Google apps, and PPC Land counts more than 40 connected third-party apps, including Instacart, OpenTable, Adobe and Shopify, starting at $19.99 a month.

Who this affects, and what to watch next

Paying Mac subscribers gain a one-window path from conversation to running code. Windows, Linux and Android users keep the standalone app. Everyone on the free tier is left watching. Google is separately offering 10,000 scientists its highest Antigravity usage tier free for six months, subject to eligibility and capacity. Two questions decide the next chapter: when the coding interface reaches the Windows Gemini app, and when Ultra-only access moves down to Pro.
