The AI stack is being rebuilt from the ground up, and most people only see one layer of it. CS 153: Frontier Systems hosted at Stanford walks through the entire architecture, from energy and silicon to foundation models and the applications reshaping how we work, create, and discover. Each week, a leader from a different layer of the stack joins to share what they're actually building and what they've learned doing it. This spring's speakers include Jensen Huang, Sam Altman, Lisa Su, Satya Nadella, Andrej Karpathy, Ben Horowitz, and founders from Sesame, Roblox, Periodic Labs, and more.Instructors are Anjney Midha, Founder, AMP PBC and Mike Abbott, ex-GM/Apple/Twitter/KP
