Unless you’ve been living under a rock with no internet access, you’ve no-doubt heard examples of how people are using the platform, and prophecies of how ChatGPT is set to change the course of society as we know it. When something this interesting shows up, surely curious minds want to know how it works. Despite having worked on Machine Learning for over a decade and having an active interest in the space, when I tried to read the research papers initially, I found it to be a daunting task. Each paper that I tried to understand referred to concepts that I did not understand, and when I tried to read another paper for those concepts, I found another set of concepts that I did not understand. It took a substantial resolve to keep following the rabbit holes till I understood the papers that describe how ChatGPT and similar technologies work from first principles.
