A machine learning technique that uses layered neural networks to find patterns across large volumes of data. LLMs are built on deep learning to make connections across billions of words and generate contextually relevant responses. So what? LLMs work by statistical pattern-matching rather than reasoning — a foundational insight for anyone designing tests. Example: An LLM predicts the most statistically likely next word or phrase, not the most factually accurate one.
"They are trained on billions of words from different sources. Using deep learning, they make connections between all the words they are trained on to answer whatever questions we ask of them." — Demi Van Malcot
