AI Foundations
Three short, hands-on lessons that teach you to predict what a language model will do, and to write prompts that get reliable answers.
Level: Beginner · For: Anyone who uses AI assistants at work and wants fewer surprises.
Lessons
- Lesson 1 · ~20 minTokens and context windowsAfter this lesson you can work out what a model can “see” on any turn of a conversation, and plan a long chat so the important parts never fall out.
- Lesson 2 · ~20 minWhy models make things up (and what to do about it)After this lesson you can recognise a likely hallucination and set up a prompt that makes one less likely and easier to catch.
- Lesson 3 · ~25 minPrompts that workAfter this lesson you can turn a vague request into a prompt that says what you want, why, in what shape, with an example.
