The 15-Millisecond AI: Building "Pre-Cognitive" Edge Caching on AWS

If you want to watch a product manager's soul leave their body, sit in on a live demo of a Generative AI feature where the model takes 12 seconds to generate a response. Typing... typing... typing... In the world of AI product development, latency is the ultimate UX killer. You can have the smartest prompt and the most expensive foundational model in the world, but if your users have to stare at a spinning loading wheel for 10 seconds every time they click a button, they will abandon your app. Most engineering teams try to solve this by streaming tokens to the frontend or switching to smaller, less capable models. But as a cloud architect, I prefer a different approach. What if we stopped waiting for the user to ask the question? What if we used the user's application state to predict what they are going to ask, generated the answer in the background, and pushed it to a CDN edge location before their mouse even hovers over the button? When I sketch this out for engineering leaders, the
