Everyone remembers their first experience with ChatGPT - an absolute mind-blowing moment! But how does GPT actually work? Many explanations mention that text is broken down into tokens and then converted into vectors, but that hardly explains how a model truly "understands" context. What role do the countless parameters play? The secret lies in the transformer architecture, which we’ll demystify here in an easy-to-understand way without complex math. Let’s unveil the magic behind generative AI and understand what makes language models like GPT so fascinating!
