NEXUS is an autonomous multi-agent AI digital twin built for Addis Ababa, Ethiopia. It integrates real-time drone perception using Meta SAM 3.1 and Llama 3.2 Vision with 11 domain agents orchestrated over Modal (Llama 3.3 70B) and Baseten (Meta Muse Spark Open). Llama-Guard 3 enforces strict safety invariants for emergency vehicle routing during city hazards.
