AI Tech Fundamentals for Non‑technical Decision Makers

The technical internals of AI, for people who make decisions about these systems without building them.

No mathematics, no code, and no assumption that you have read anything else first. Each part answers one question, in order: what a model is, what is inside one, what it costs, where it stops, and how to choose.

  1. 1What a Model IsThe object, what it does, what kinds there are.
  2. 2Inside a ModelWhat is actually in there, how it produces an answer, and how it was made.soon
  3. 3What It CostsThe two scarce things, who pays for each, and every lever that moves them.soon
  4. 4Where It StopsThe limits that no release will fix, and what each failure looks like.soon
  5. 5How to ChooseJudging cost properly, what actually improves results, and the decisions worth making.soon
