On May 19, 2026, alongside Google I/O 2026, Google substantially overhauled its AI agent development platform, "Google Antigravity," and announced a standalone desktop application called "Antigravity 2.0" [1]. The company also lined up a full set of entry points for building and running agents at once — a CLI, an SDK, an enterprise edition, and Managed Agents accessed through the Gemini API [1][2].
Antigravity 2.0: A Desktop App That Runs Multiple Agents in Parallel
Antigravity 2.0 is a new standalone desktop application optimized for interacting with agents [1]. Its defining feature is the ability to direct multiple agents from a single place and have them run tasks in parallel, and Google positions it as the central hub for agent interaction [1]. It includes dynamic subagents for parallelized workflows, scheduled tasks that run automatically in the background, and ecosystem integrations spanning Google AI Studio, Android, and Firebase [1].
The foundation is "Gemini 3.5 Flash," a new model announced at I/O 2026 [1]. According to Google, 3.5 Flash outperforms the higher-tier Gemini 3.1 Pro across almost all benchmarks while running four times faster than rival frontier models, and it is positioned as the high-speed engine that powers practical agent workloads [1].
Expanding the Ecosystem with a CLI, SDK, and Enterprise Edition
Beyond the desktop app, Google prepared multiple entry points into Antigravity [1]. For developers who prefer working in the terminal, it introduced the lightweight "Antigravity CLI," which lets you create agents instantly without a GUI [1]. Google encourages existing Gemini CLI users to migrate to Antigravity CLI [1], and TechCrunch reports that the move effectively retires the Gemini CLI for consumer users [2].
The "Antigravity SDK" provides programmatic access to the same agent harness Google uses in its own products, letting developers define custom agent behaviors and host them on the infrastructure of their choice [1]. In addition, through Antigravity on the "Gemini Enterprise Agent Platform," Google Cloud customers can connect Antigravity directly to their own Google Cloud projects [1].
On the Gemini API side, "Managed Agents" lets developers spin up an agent in an isolated Linux environment with a single API call [3]. It likewise runs on the Antigravity agent harness and Gemini 3.5 Flash, serving as an option for developers who want to invoke agents from code without using the desktop app [3].
AI Studio Integrations, a New "AI Ultra" Plan, and a Hackathon with a USD 2 Million Prize Pool
Google AI Studio was also expanded [1]. With the new mobile app — available for pre-registration this week — you can jot down an idea while out and about and have a working prototype waiting by the time you get back to your desk [1]. Native integration for building Android apps from a prompt alone, along with a feature to publish directly to the test track via the Google Play Console, were also added [1].
On pricing, a new "Google AI Ultra" plan starting at USD 100 per month (about 15,900 yen) *Converted at 159 yen to the dollar made its debut [1]. Its Antigravity usage limit is set five times higher than the "Google AI Pro" plan, and for a limited time it includes USD 100 (about 15,900 yen) in bonus credits. The deadline to claim this offer is May 25, 2026 [1].
Google also announced the "Build with Gemini XPRIZE Hackathon," with a total prize pool of USD 2 million (about 318 million yen) *Converted at 159 yen to the dollar [1]. Google says this is the largest prize pool ever for a hackathon, and finalists will deliver their final pitches at the "Moonshot Gathering" held in Los Angeles in September [1].
Summary
With this announcement, Google has put in place a structure where developers can reach Antigravity through multiple entry points — the desktop app, the CLI, the SDK, the enterprise edition, and the Gemini API. The intent appears to be to make the shift in development style — from one-off prompts to multiple, always-on agents — as frictionless as possible. Including the push to migrate away from the Gemini CLI, Google's intent to make Antigravity the centerpiece of agent development seems clear.
