ChatGPT, Claude and Gemini are all LLMs — large language models: giant neural networks (pattern-matching maths loosely inspired by the brain) trained on mountains of text. Underneath, they all do one thing: predict the next word, then the next. Not thinking, and — unless it stops to search the web — not looking anything up. Just very good guessing. Once that clicks, everything else about these tools makes sense.
Run the steps to begin — the prompt types itself in, and the model answers.
