Summary:

• **AI Agents Working Together**: Sixteen Claude AI agents (computer programs that can think and make decisions) worked as a team to create a new C compiler, which is a special tool that translates computer code into instructions a computer can understand. This shows that AI can collaborate just like humans do to solve big, complicated problems.

• **What Makes This Special**: Instead of one AI doing all the work, multiple AIs shared different jobs and helped each other, similar to how a team of workers each does their own part to build something. This teamwork approach helped them successfully build something that would normally take human programmers a lot of time and effort to create.
