AI at Roblox: From Models to Multiplayer Worlds

In this episode of Tech Talks, Roblox Founder & CEO Dave Baszucki is joined by Kiran Bhat and Alberto Hojel for a deep dive into new techniques for creation powered by generative AI. We explore how Roblox's 3D-native foundation model builds on powerful ideas from text and image modalities, allowing creators to build functional 4D objects and worlds from prompts. We also discuss our vision for real-time video world models for gaming, leveraging our 3D simulation backbone. If you've ever wondered how AI scales to millions of players in a shared, physics-based environment, this deep dive is for you.
