We’re rolling out Orchestrator in
@Antigravity to Google AI Ultra subscribers, letting you run multiple models in a single session instead of routing the entire task to one model.
Orchestrator pairs a frontier model with a fast execution model: Carbon sets the plan, hands off code edits and testing to Hydrogen, and steps back in to repair the plan if it hits friction — reaching near-Carbon task success rates on Terminal-Bench 4.0 while consuming 24% less quota and completing 19% faster on average.
