The way ChatGPT works is by trawling the web, analysing what words come next in a sentence and what fraction of the time, and assigning probabilities to each word. It then chooses the most likely answer to any prompt. It’s like a very sophisticated version of predictive text messaging, however with a twist, that it can be trained to improve its answers using human input (GPT stands for generative pre-trained transformer).
