Google launches Antigravity, an AI-first coding platform built on Gemini 3
Google has launched Antigravity, a development platform that transforms how AI agents write and test code by giving them direct control over editors, terminals, and browsers—transforming them from helpful assistants into independent software developers that can build, test, and verify their own work.
The platform runs on Gemini 3 Pro—which tops the LMArena leaderboard with a 1,501 Elo score and achieves 76.2% on SWE-bench Verified—and additionally supports Claude Sonnet 4.5 and GPT-OSS. It’s available for download on Windows, macOS, and Linux.
