Core Concepts

Foundational ideas that underpin the entire playbook — how AI works, why it fails, and how to communicate with it effectively.

Before diving into exercises and pillars, it helps to understand a few foundational ideas. These concept pages give you the mental models you need to use AI well — no technical background required.

• What We Mean by AI Fluency — What AI fluency actually is, why it matters for generalists, and how the five pillars fit together
• How AI Actually Works — What happens when you type something into ChatGPT, Claude, or Gemini
• Tokenization & Context Windows — Why AI can only "remember" so much, and what you can do about it
• Why AI Gets Things Wrong — What hallucinations are, why they happen, and how to catch them
• Prompt Engineering Basics — How to communicate with AI effectively using clear, structured instructions
• Agents vs. Assistants — The spectrum from simple chatbot to autonomous agent, and how to choose the right level

These pages are referenced throughout the playbook's exercises and pillars. You don't need to read them all before starting — but they're here when you want to understand the why behind the techniques.
