On the first day of Google I/O 2026, Antigravity 2.0 made its debut—not as an IDE update, but as a completely separate desktop application for macOS, Linux, and Windows. Google admitted that bundling the agent interface inside the IDE was "not intuitive," especially for non-coders. The new version removes the IDE entirely, leaving only the agent.
Powered by Gemini 3.5 Flash: 4x Faster, Enhanced Agent Capabilities
Antigravity 2.0 runs on the Gemini 3.5 Flash engine. According to Google's benchmarks, the model outperforms Gemini 3.1 Pro on coding and agent tasks while being 4x faster. A key new feature is dynamic subagents: the main agent can create and invoke sub-agents on the fly to handle sub-tasks, preventing context window overload and enabling parallel processing. Asynchronous task management lets tasks run in the background without blocking the main agent from handling other commands.
However, similar capabilities have been available in Claude Code and Codex for some time, making this less of a breakthrough.
Finer Control: JSON Hooks and Scheduled Tasks
New JSON hooks allow users to define a simple JSON config file to intervene, override, or block agent actions at critical execution points. Non-developers can exert fine-grained control without reading code.
Scheduled Tasks bring cron-based triggers: agents can launch automatically at set times. The new slash command /schedule supports natural language input like "summarize my inbox every morning at 9 AM." Other new commands include /goal (run until completion without interruption), /grill-me (agent asks clarifying questions), and /browser (explicitly control browser usage).
Five-Layer Platform and Pricing Changes
The full Antigravity platform now comprises five layers: desktop app, CLI, SDK, Gemini API's Managed Agents, and Enterprise Gemini Platform. The app natively integrates with AI Studio, Firebase, and Android; AI Studio projects can be exported with context.
Subscription plans have been updated: a new AI Ultra $100/month tier (5x Pro usage cap) and the existing AI Ultra tier reduced from $250 to $200/month (20x Pro usage cap). Google is not shutting down Antigravity IDE immediately; both apps will coexist temporarily. But the company plans to remove Agent Manager from the IDE, turning it into a pure agentic development environment.
