This week brought exciting news about AI agents working together to solve big problems. AI agents are computer programs that can think and act on their own, like digital helpers.

The biggest news came from PwC, a major business company. They announced they built over 120 AI agents that work together as a team. These agents help businesses in many ways, like finding problems in stores, helping doctors with patient files, and checking company rules. What makes this special is that the agents can talk to each other and share work, just like people do in an office.

Meanwhile, scientists at Stanford University in the United States created something amazing. They made AI agents that can do science experiments by themselves. These AI scientists held meetings, came up with ideas, and tested new medicines for COVID-19. The best part? They did 90% of the work without human help. Two of their new medicines actually worked well in tests.

Companies are also worried about keeping AI agents safe when they work together. Okta, a security company, held a special meeting about this problem. They said that when AI agents share information with each other, it can create security risks. They are working on new rules to make sure agents can collaborate safely.

Google Cloud made a big partnership with Atlassian, the company that makes work tools like Jira. This partnership will help AI agents work better with the apps people use every day for work. The agents will be able to understand what workers need and help them faster.

Experts say that 2025 is the year of agent collaboration. Instead of just one AI helper, businesses are now using many AI agents that work as a team. This helps companies work faster and save money, but it also means they need better ways to control and watch what the agents are doing.
