Google Antigravity Rolls Out Orchestrator for Dynamic Model Handoffs

Google Antigravity launched Orchestrator, a feature for Google AI Ultra subscribers that dynamically switches between Gemini 4 Carbon and Hydrogen models during a session, improving task success and efficiency. Hydrogen, a rapid-execution model, is also rolling out to paid Google AI Pro and Ultra users, while enterprises can access both via Gemini for business. Orchestrator enables flexible model handoffs to optimize reasoning depth and execution speed in development workflows.
