Large language models like ChatGPT are powered by a clever design called the transformer, and it changed everything. First, your words are split into tokens and turned into numbers the model can process. Then attention lets every token look at all the others, weighing which ones matter most. Stacking many of these attention layers builds a rich, layered understanding of the full context. Finally, the model predicts the next word, one step at a time, until a full answer appears.
