I have had a few conversations in the past year with non-technical folks (traditional finance types, consultants) who asked for a simple explainer on how GPTs work. These people generally have the horsepower to grasp new concepts quickly but don t necessarily have the math background to dig in super deeply and want a stronger framework than they predict words .I had generally been pointing them to Karpathy, Illustrated Transformer, and other youtube content but I figured something more hands on without the math requirement might be better at explaining questions like why matrix multiplication? .I built this as a simple 60-70 minute interactive course with some demos I could send along to them. I ve found it effective as the initial foray into understanding jargon and concepts before they graduate to Karpathy et al.It s free, no signup required. I would love feedback on where it might lose a non-technical reader, and where someone who does this for a living thinks I have simplified past the point of being correct.understandgpt.xyz
