Google Launches Antigravity CLI, Deprecates Gemini CLI
Google deprecated Gemini CLI at Google I/O, replacing it with Antigravity — a terminal interface for running AI agents from the command line. The move completes a cross-lab pattern: xAI (Grok Build), Anthropic (Claude Code), and Google (Antigravity) all now ship shell-resident agentic coders with comparable feature sets including plan modes and parallel execution. Antigravity is built on Gemini 3.5 Flash and powers Google's Managed Agents platform, positioned as the "most cost-effective generalized agent sandbox" for developers.
Why It Matters
Terminal-native agent execution has become the converging paradigm across every major AI lab. Antigravity's dual role as dev tool and Managed Agents backend makes it foundational infrastructure, not just a developer convenience.
