Nvidia, the US chipmaker whose processors power most of the world's artificial intelligence (AI) systems, says cities around the world are using its technology to run public services and manage traffic and infrastructure.
In a blog post, the company highlighted projects in Spain, the San Francisco Bay Area, Poland, Malaysia, Nigeria, Taiwan and Morocco.
Nvidia said cities already collect huge amounts of information from cameras and sensors but often struggle to put it to practical use.
Its software is designed to help them do that.
The tools include AI that can analyse video footage, AI agents that can carry out tasks such as answering questions or booking appointments, and digital twins, which are virtual copies of real places used to test changes before they are made.
Chatbots for residents
In Spain, a company called 1MillionBot has built AI assistants that help residents with council paperwork and appointments in Madrid and Catalonia.
It now has more than 150 of these systems running across Spain.
In the Bay Area, LiveX is developing AI hosts that can talk to visitors at airports and hospitals.
Cameras and traffic
In Poland, K2K is using Nvidia's technology to turn camera footage into information about traffic and public safety.
In Malaysia, ITMAX plans to expand its AI camera system to more than 17,000 cameras by 2027.
It says the system has cut journey times on busy roads at peak hours by up to 26%.
Refineries, forests and ports
In Nigeria, Africa's largest oil refinery, run by the Dangote Group in Lekki, is using AI agents to help manage operations.
