Cities around the world are using smart computer systems and AI agents to plan better neighborhoods and manage their growth. One exciting example is AI Polis, a new platform that helps city leaders make smarter decisions about building homes, roads, and other important things—while keeping nature safe. The platform works like a super-smart helper that brings together information about climate, energy, water, and what people need to live well.

AI agents are also being tested in Europe through a project called SPACE4Cities, which uses pictures taken from space satellites to help cities prepare for problems like extreme heat and floods. One of the tools being tested is called CityMotion, which are AI agents designed to keep cities running smoothly and protect important buildings and infrastructure.

The world is also building many new data centers—massive buildings filled with computers—to power all this artificial intelligence technology. Credit rating companies say the world will spend about $3 trillion over the next five years to build these data centers. These huge construction projects need lots of smart planning, which is where digital twins come in. Digital twins are like video game models of real cities that help engineers test ideas before actually building things. They can reduce project problems by up to 50%.

Countries like Canada are becoming important places for building AI data centers, with government help and special funding. Meanwhile, cities are using AI tools to figure out construction schedules faster, spot problems early, and make sure everything works together smoothly.

These new technologies show how AI agents and smart computer systems are helping cities grow in ways that work better for people and help protect the planet.
