Horizon

Lifeline is an autonomous crisis-operations marathon agent that maintains live situational awareness during building emergencies and continuously replans evacuations as conditions change. Gemini 3 Pro handles long-horizon reasoning—tracking zones, hazards, capacities, and accessibility routes—while Nano Banana Pro generates updated 2K evacuation maps by editing a base floorplan with hazard overlays, blocked paths, and clear arrows. When an operator reports an event like “Fire in Zone B,” the agent analyzes impact, updates building state, recalculates safe paths, and issues new instructions. Lifeline demonstrates how Gemini 3’s reasoning and multimodal capabilities can support real-world crisis response with speed, transparency, and reliable map updates.
