“How did the model know what an immersion heater or a solar coil was, when I never explained it?”
AI Tool has a searchable file of every document it was trained on, and looks things up in it.
AI Tool's knowledge of immersion heaters comes from statistical patterns learned across huge amounts of text, not a lookup.
If a document wasn't in AI Tool's training data, it's mathematically impossible for the model to say anything relevant about the topic.
Hundreds of billions of words — manuals, forum posts, product descriptions, and far more — read once, during training.
A much smaller set of adjustable numbers — statistical structure distilled from all that text, not a copy of it.
True or false: 'AI Tool has a searchable file of every document it was trained on.' Explain why.
