How AI Chatbots Actually Work (and Why They Sometimes Make Things Up)
Large language models predict words, not truth. Understanding this helps you use them wisely for anything money-related.
AI chatbots have become a common place to ask questions — including questions about money. To use them well, it helps to understand what they are doing under the hood.
A large language model is trained to predict the next word in a sequence, based on patterns from enormous amounts of text. It does not look things up in a database of facts; it generates text that is statistically likely to follow your prompt.
That's why these tools can 'hallucinate' — produce a confident, fluent answer that is simply wrong. A chatbot might invent a tax rule, misstate a deadline, or cite a regulation that doesn't exist, all in a perfectly reasonable tone.
For financial questions, treat a chatbot like a well-read friend, not a professional. Use it to understand concepts, draft questions, or organize your thinking. Verify anything specific — rates, deadlines, legal rules — against an official source before you act.
Also be careful what you type in. Avoid pasting account numbers, full statements, or identifying details into any AI tool unless you have read and understood how that provider stores and uses your data.
