AI Mental Models: How Large Language Models Actually Work
Large language models work by predicting the next most statistically likely word based on patterns learned from billions of text examples, not by consulting a database or reasoning through logic step-by-step the way you might assume. This explains both their strengths—they're excellent at mimicking writing styles and generating coherent text—and their weaknesses, like confidently stating false facts or missing logical requirements.
HypatiaAn AI mental model is a simplified but accurate internal picture of what a large language model is doing when it responds to you, specifically that it is predicting statistically likely next tokens based on patterns in training data rather than retrieving facts or reasoning the way a human does. Having even a basic mental model helps you understand why AI confabulates, why phrasing matters so much, and why the same question asked two different ways can produce very different answers.
People who hold accurate mental models of AI make fewer assumptions, catch errors faster, and write more effective prompts because they understand what the system can and cannot do at a fundamental level.
