Fable 5.2 coordinates 1,000+ subagents to build a bootable OS in 8 days

In an experiment, an Anthropic engineer gave Fable 5.2 the task of designing a prototype operating system. Starting from an empty folder, the model coordinated over 1,000 subagents working around the clock for 8 days, writing, testing, and reviewing code.
The result is a working OS that boots on a laptop, with:
- its own kernel
- drivers for disk, keyboard, network, and file storage
- a login screen and windowing system
- built-in Claude functionality
