› Hi, Bot Builder · Sand to Agents
From sand to agents, in 30 models.
Every AI answer rests on a stack of real machines. Walk the line from the energy that powers it to a machine that learns, and build each one for real. New to the ideas underneath? Start with AI Foundations.
Start with these five
Switch → logic → parallel compute → cluster → learning. Those five cover the whole path from one switch to a machine that learns; the other 25 fill in around them.

Brick build coming means the step-by-step brick booklet for that model isn't out yet; booklets arrive one model at a time, starting with the Starter Five. New booklets are announced by email once they open to everyone: get the free printables list.
