In this episode, Josh Liss (Head of Media & Entertainment at Nebius) sits down with Alberto Taiuti, CEO and Co-founder of Reactor, the developer platform for world models. They unpack what real-time world models actually are, why they're fundamentally different from the AI video tools most people have encountered, and why he believes the era of prompting is already winding down.
Drawing on his background at Apple, where he worked on the Vision Pro, Alberto makes the case that interactive video changes what a developer platform has to be, why video models already understand 3D space (even though no one trained them to), and how shows, ads, and even software interfaces could be generated live, per user, in real time.
