Andrej Karpathy and AI systems

If you’re serious about AEO (Answer Engine Optimization), you should have a solid understanding of how AI systems work.

Andrej Karpathy is my favorite teacher on this subject. He has a rare ability to explain how AI systems work in a way that’s both substantive and approachable.

I’m sharing his Y Combinator talk here, deep-linked to the “Build for Agents” section. That segment, in particular, heavily influenced how we’re thinking about product direction at aeo.press.

In a few areas (.txt files!), we’re ahead of the curve based on Karpathy’s recommendations. Give it a listen and let me know if you agree.
