// about Google Antigravity
Google Antigravity is an agentic IDE that lets AI agents operate directly across the editor, terminal, and browser instead of just answering prompts in a side panel. Version 2.0 added scheduled background tasks, a standalone CLI, and a public SDK, with support for Gemini 3 Pro alongside Claude Sonnet 4.5 and OpenAI models.
