Google rolls out Gemini 4 Argon in Antigravity for AI Ultra subscribers
WesRoth says Google is pushing Argon to Ultra subscribers via the desktop app and CLI, citing 35% more agentic code and 30% fewer post-submit rollbacks after four weeks of internal use, though the standalone IDE is not yet supported.

Google is rolling out Gemini 4 Argon in Antigravity for Google AI Ultra subscribers, with access through the desktop app and CLI. Across four weeks of internal use, Google reports a 35% increase in agentic code and a 30% decrease in post-submit rollbacks. One detail to check before opening your editor, Google’s documentation lists support for IDE extensions, but excludes the standalone Antigravity IDE. For teams maintaining existing software, fewer changes needing to be reversed could be the more valuable improvement.
