The 5 things to understand about how AI actually works
Skip the hype and the doom. Five plain-English ideas that prevent the mistakes almost every beginner makes.
Most people's first problem with AI isn't the tools - it's a wrong mental model. Once you understand what these systems actually do, most of the frustration disappears. Here are the five ideas we teach first in every workshop.
1. It predicts the next word
A chatbot like ChatGPT, Claude or Gemini is, at its core, a system that predicts the most plausible next word - then the next, then the next. Everything impressive it does emerges from doing that astonishingly well, at massive scale.
It's autocomplete that went to university.
This single reframe - from "thinking robot" to "very sophisticated prediction engine" - prevents most beginner mistakes. It doesn't "look things up" by default; it generates the most plausible-sounding continuation.
2. Tokens are the currency
Text is counted in tokens - roughly three-quarters of a word. You pay per token, and limits are measured in tokens. The practical takeaway: concise is cheaper and faster. When you scale something up, tokens are what you're spending.
3. The context window is its short-term memory
A model can only "hold in its head" so much at once. That space is the context window. When a chatbot seems to "forget" what you told it earlier, it simply ran out of room. Keep what matters recent, and start a fresh chat for a genuinely new task.
4. It hallucinates
Plausible is not the same as true. A model will invent facts, quotes and citations with total confidence, because sounding right is exactly what it's optimised for. Verify anything that matters - especially anything involving money, data, or facts other people will rely on.
5. Agentic AI acts - it doesn't just answer
This is the big shift. Give an agent a goal and it plans, takes actions, uses tools, fixes its own errors and reports back. You direct; it does the work. We'll cover agents in depth in another post - but holding the distinction in mind changes what you think is possible.
The mindset: you're not searching, you're directing. Direct clearly, verify what matters, and you're already ahead of most people. That's the foundation everything else in our workshops builds on.
