The architecture that powers ChatGPT, BERT, and every major AI breakthrough of the last 5 years — explained in under 4 minutes. Before 2017, AI models processed language one word at a time. Slow. Limited. Bottlenecked. Then "Attention Is All You Need" changed everything. In this video, you'll discover: – Why sequential processing was holding AI back – The elegant math behind the attention mechanism – How a simple formula (softmax(QK^T/√d) × V) revolutionized machine learning – Why GPUs were secretly waiting for this architecture – How the same design now powers text, images, audio, video, and code Timestamps: 0:00 – The Bottleneck (Why RNNs Failed) 0:38 – The Core Mechanic (Attention Explained) 1:13 – The Magic Transform (Matrix Multiplication) 1:53 – Not Just Attention (Multi-Head & Architecture) 2:32 – Enabled Scale (Parallelization & Beyond) This isn't magic. It's matrix multiplication — done brilliantly. https://www.youtube.com/watch?v=Bs4nUcKpzYY
