The applications mostly interpret video and sensor data to spot things needing attention, such as traffic congestion, equipment condition, underused spaces or safety hazards. In the U.K., the Liverpool City Region is exploring AI factories with K2K for urban planning, mobility and safety, while Innovation City Belfast is looking at a pilot covering smart mobility, citizen safety and event response. Jersey is working with K2K on decision-making, mobility and clean energy.

Some deployments report concrete results. In France, the Department of Côte-d'Or, Akila and ThinkDeep built agents on a sovereign digital twin covering more than 500 public buildings; they reportedly cut document search time from weeks to minutes and reduced total operating costs by 10%, targeting 30% at scale. In Italy's Milan region, Galene AI, Dell and TD Synnex are running a locally operated AI factory starting in Cinisello Balsamo, offering real-time translation, citizen chatbots and help with procurement, while keeping data under local governance.

Other pilots lean on synthetic data where real-world examples are scarce: at the Port of Antwerp-Bruges, Milestone and Dell are testing vision AI for use cases such as oil-spill warnings, training models on simulated incidents. In Sweden, Younite is building an Omniverse digital twin for Gothenburg under the EU's Citiverse initiative, letting residents preview event entrances, seating and crowd conditions before arriving. Scaling from pilots to daily operations depends on locally operated AI factories from system builders such as Cisco, Dell, HPE, Lenovo and Supermicro, with EY and Accenture handling integration.

NVIDIA and its partners are presenting this work at the Smart City Expo World Congress in Barcelona, running 3 to 5 November.
