On the first day of Google I/O 2026, Google announced the launch of Antigravity 2.0, a standalone desktop application supporting macOS, Linux, and Windows, which is now completely decoupled from the original Antigravity IDE as two separate products. (Context: Google officially launches "Gemini 3"! The world's smartest AI model, what are the highlights?) (Background: Google launches the most powerful "autonomous agent and software development" model, Gemini 3.5 Flash! Writes an operating system in 12 hours for under $1,000) On the first day of Google I/O 2026, the core agent interface from the Antigravity IDE, which was only released in November 2025, was extracted and spun off into a brand-new desktop app named Antigravity 2.0. In its official documentation, Google admitted that bundling the IDE and the agent into the same app was "not intuitive" and created a barrier for users unfamiliar with code. The solution in 2.0 is to remove the IDE and keep only the agent. Antigravity 2.0 is powered by Gemini 3.5 Flash. According to benchmarks released by Google, Gemini 3.5 Flash outperforms Gemini 3.1 Pro in coding and agent tasks, with 4x faster speeds. One of the core mechanisms introduced in the new version is dynamic subagents. Simply put, the main agent can define and call subagents during execution to complete subtasks, preventing the main agent's context window from becoming overloaded while allowing multiple subtasks to be processed in parallel. This is paired with asynchronous task management: tasks can run in the background without blocking the main agent from processing other instructions. However, these features have already been implemented in claude code and codex for some time, so they are not particularly attractive new features. At the same time, 2.0 adds JSON hooks. Users can use a simple JSON configuration file to intervene, rewrite, or block agent behavior at critical moments, allowing non-engineers to exercise fine-grained control over agents without needing to understand the underlying code. Another new mechanism is Scheduled Tasks: using cron scheduling to define trigger times, agents can start automatically at specified moments, paired with the new slash command /schedule, allowing users to input instructions like "Summarize my inbox every morning at 9 AM." New slash commands also include /goal (specifies a goal and runs until completion without intermediate prompts), /grill-me (the agent proactively asks questions to clarify requirements), and /browser (explicitly controls whether the browser is used). The complete Antigravity platform now consists of five layers: the desktop app, CLI, SDK, Managed Agents for Gemini API, and the Enterprise Gemini Platform. Antigravity also features native integration with AI Studio, Firebase, and Android, allowing AI Studio projects to be exported directly with context. Subscription pricing has been adjusted simultaneously: a new AI Ultra $100/month plan has been added (5x the Pro usage limit), and the original AI Ultra has been reduced from $250 to $200/month (20x the Pro usage limit). Google has not immediately shut down the Antigravity IDE, and the two apps will run in parallel for the time being; however, Google has announced that it will remove the Agent Manager from the IDE, allowing the IDE to return to being a purely agentic IDE.
