By analyzing and processing this vast amount of text, the language model learns the patterns, the language, and the context of how words, sentences, and paragraphs fit together. If you were to ask a large language model like GPT-4 a question, it would know what to reply based on its training from all those books, web pages, video transcripts, and social media posts. What it lacks in real-world sensory experiences of the human brain, it compensates for by having exposure to more language than any human might hope to read, watch, or listen to in multiple lifetimes.
