This week brought big news about teams of AI helpers called multi-agent systems. Amazon launched AgentCore, a new toolkit that lets businesses build and manage groups of AI helpers safely. OpenAI released a special Agent mode for ChatGPT that can shop online and make plans for users, though it's not available in Europe yet.

Hospitals are using teams of AI helpers too. A company called Codex Genetics showed how AI teams can match patients to the right medical studies faster. Customer service centers are using groups of specialized AI helpers that work together like ants in a colony to solve problems quickly.

Experts say these AI teams will change how we work. Humans will focus on big decisions while AI handles routine tasks. But people worry about trust and safety when AI makes choices on its own. Companies are investing heavily, with Amazon adding $100 million to develop these systems.
