The 10% in Côte-d'Or is a figure inside this post

NVIDIA's European-cities post today says France's Côte-d'Or, Akila, and ThinkDeep built operations agents that combine sensor, infrastructure, and historical data in what they call a sovereign digital twin. Across more than 500 public buildings, the agents cover energy, compliance, safety, and climate resilience. The post says document search went from weeks to minutes and total operating costs fell 10%, with a target of 30% at scale.

That is the project's account in the post, not an independent audit. The video credit says Akila.

Milan has seconds and hours. Other places are still trials

Around Milan, Galene.AI, Dell, and TD Synnex are deploying a locally operated AI factory, starting in Cinisello Balsamo and planning four more municipalities. Uses include live translation, citizen chat, and help with procurement and funding. The post says municipal data access goes from hours to seconds, with data governance kept local. It does not say how many residents are covered.

Liverpool City Region and K2K are exploring how to build factories and testing mobility and safety. Jersey and Belfast are exploring or piloting. At the Port of Antwerp-Bruges, Milestone and Dell are testing, using synthetic data for cases such as oil-spill warnings where real samples are scarce. The detection steps are not repeated here. Gothenburg is a digital-twin experience under the EU Citiverse effort.

The list also includes a hotel

The same post says Honeywell is deploying Forge Cognition at the Fairmont in Dubai, connected to building systems. That is a hotel, not a city government. The Smart City Expo in Barcelona is set for November 3 to 5. It has not opened. Reading the headline as a finished map would put exploring, testing, and a hotel in the same stage.
