Cities around the world are getting AI agents that work like digital assistants to help with everyday problems. These smart systems are changing how cities operate and how people interact with city services.

In Buenos Aires, Argentina, the city government created an AI chatbot called Boti that lives on WhatsApp. What started as a simple COVID-19 information bot has grown into a powerful city assistant. Boti can look at photos that people send, like pictures of license plates for parking violations. It can also alert people about emergencies and let residents report crimes directly through their phones. The bot talks in a friendly way and even works in English for tourists visiting the city.

Other cities are using AI vision systems to spot problems automatically. Lisbon, Portugal and Tempe, Arizona are testing AI that can find graffiti without human help. The systems use cameras mounted on cars or flying drones to scan the city. When they spot new graffiti, they mark the exact location on a map so city workers know exactly where to go. This means cities don't have to wait for people to call in complaints - the AI agents find problems on their own.

Tokyo, Japan has created something called Plant Doctor to take care of the city's trees. This AI system was built by universities and uses advanced computer vision to look at tree leaves. The AI can spot signs of disease or bug damage before trees become dangerous. Drones and vehicles carry the Plant Doctor cameras around the city, checking thousands of trees automatically. This helps keep Tokyo's urban forest healthy and saves money on tree maintenance.

New York City is using AI to check crosswalks and make sure they're safe for people walking. The AI looks at thousands of photos from car dashcams to see if crosswalk paint is wearing away. Shanghai and Singapore have built digital twins - computer copies of their entire cities that help planners test new ideas before building them in real life.

To power all these AI agents, tech companies are building the biggest computer centers ever seen. OpenAI, Oracle, and SoftBank announced five new massive data centers across the United States. These facilities will cost over $400 billion and create more than 25,000 jobs. The new centers are being built in Texas, New Mexico, and Ohio.

The Stargate project represents the largest AI infrastructure build in history. These aren't just regular computer centers - they're designed specifically to run the AI systems that will power smart cities. The facilities will use nearly 7 gigawatts of electricity, which is enough power for several million homes. Instead of powering houses, all that electricity will run AI systems that help cities work better.

OpenAI and Nvidia have partnered to build even more computing power - up to 10 gigawatts total. This massive amount of computing power will train the next generation of AI agents that cities will use. The partnership includes a $100 billion investment from Nvidia to help build these systems.

The companies chose locations for their data centers very carefully. They looked at over 300 proposals from more than 30 states. The winning locations were picked because they have reliable electricity, good internet connections, and supportive local governments. Texas got three of the five new facilities because it has lots of available land and energy.

These changes mean the future of cities will look very different. AI agents will constantly monitor air quality, traffic flow, and city infrastructure. They'll help people get services faster and spot problems before they become dangerous. The technology that once seemed like science fiction is now becoming everyday reality in cities around the world.

The massive investment in AI infrastructure shows that companies believe these smart city systems will become essential. As more cities adopt AI agents, the demand for computing power will only grow. This weekly update shows we're witnessing the beginning of a new era where cities and AI work together to make urban life better for everyone.
