The forces shaping how AI systems are built — from the people engineering them.

Essays, community stories, and project updates — everything from the desk.

Original essays on the shifts reshaping AI engineering. Each piece names a change most people miss, backs it with evidence, and explains what it means for anyone building or leading in technology. These are the pieces worth forwarding to a colleague.

The people building AI systems around the world. Students shipping real hardware projects, educators bringing ML systems into new classrooms, and practitioners pushing the field forward. Every spotlight is also an invitation: want to be featured next?

Build it yourself. TinyTorch modules, hardware kit programs, interactive labs, and new textbook chapters. Everything here is something you can use, run, or teach with. Because you cannot debug what you did not build.
