Cities around the world are using artificial intelligence to become smarter and safer places to live. One of the biggest examples is Dublin, Ireland, which is building a digital twin of the entire city using AI. A digital twin is like a computer copy of a real city that helps leaders understand what is happening on the streets and make better decisions.

Dublin's digital twin tracks how people move around the city by using AI sensors on roads. These AI agents are smart computer programs that watch traffic and look for dangerous situations, like a car getting too close to a bike rider. When the AI agents find a problem, they can alert city workers right away so they can help keep people safe.

In November, Dublin showed off this work at a big technology conference in Barcelona, Spain called the Smart City Expo World Congress. Other cities joined Dublin at the event, including Ho Chi Minh City in Vietnam and Raleigh, North Carolina in the United States. These cities are all using the same type of AI technology to help solve city problems like traffic jams and safety issues.

Raleigh is using a special AI agent that watches camera video from streets and parks. This AI agent looks at the video and creates alerts that help city workers respond quickly to problems. Another exciting project is happening in Rio de Janeiro, Brazil. Rio is building an AI city with special laser-based internet that connects everything together. These smart city projects show that AI is changing how cities work by predicting problems and fixing them faster.
