Google Antigravity

Google Antigravity is an agentic coding environment built around Gemini models. Tasks are described in plain language and carried out across the editor, a terminal and a browser rather than in a chat panel alone.

Orchestrator, added on 12 November 2026, routes a single task between models while it runs. Gemini 4 Carbon or Gemini 4 Argon plans the work and Gemini 4 Hydrogen writes the edits and runs the tests, so the heavier reasoning model is only paid for on the part that needs it. It is available to Google AI Ultra and paid Google AI Pro subscribers at no separate charge.
