Gemini 4 Hydrogen launches in Google Antigravity with Orchestrator model mixing
clmt · x · 2026-11-13
Google launched Gemini 4 Hydrogen inside Antigravity alongside the new Orchestrator, which dynamically pairs heavyweights within one session — e.g. Gemini 4 Carbon for architecture and Hydrogen for blazing-fast repo edits and execution, a big unlock for agentic coding.
The Antigravity site details the agent-first platform family:
- Antigravity App: a command center to manage multiple local agents in parallel, with Projects, multi-workspace operation, and scheduled-message automation;
- Antigravity CLI: a lightweight, terminal-first surface for autonomous coding agents, shell commands, and background subagents;
- Antigravity IDE: a full agentic IDE with agent manager, artifacts, and deep codebase understanding;
- plus an Antigravity SDK for prototyping custom agents. Desktop builds available on macOS, Windows, and Linux.
