Generative AI Foundations

How large language models actually work, what they do when you type, why they get things wrong, and how to judge them. No maths, no code.

Pathaxis · Original content

Written in house, from the work rather than from a syllabus. Every example is one we would use ourselves, and every quiz question explains why its answer is right.

What you’ll learn

  • Reason about tokens and why they shape cost and behaviour
  • Tell prediction apart from retrieval, and know why it matters
  • Recognise the failure modes that follow from how models are built

Before you start

  • · No technical background needed
  • · Some hands-on use of a chat assistant helps
