Linux computer with 843 components designed by AI boots on first attempt

Probably should have linked to the actual report and not a second-hand condensation of it: https://www.quilter.ai/project-speedrun#

What does "designed by AI" mean this time? The output appears to be a set of Gerbers, BOM and pick/place files, but what was the input?

1. A schematic of a reference design with all components specified, and a library of components with correct footprints.

2. A block diagram with the major components, but nothing too specific. Free reign of Digikey.com.

3. "Computer, make me a linux board, and make it snappy!"

(I think 1 is closest)

Designed with AI, not by AI.
