Thought experiment in the National Library of Thailand from MediumWith the advent of ChatGPT, large language models (LLMs) went from a relatively niche topic to something that many, many people have been exposed to. ChatGPT is presented as an entertaining system to chat with, a dialogue partner, and (through Bing) a search interface.* But fundamentally, it is a language model, that is, a system trained to produce likely sequences of words based on the distributions in its training data. Because it models those distributions very closely, it is good at spitting out plausible sounding text, in different styles. But, as always, if this text makes sense it’s because we, the reader, are making sense of it.
