Justin Johnson on World Models and the Future of Spatial AI
CSProfKGD · x · 2026-09-02
In this TWIML podcast episode, Justin Johnson, co-founder of World Labs, discusses the frontiers of world models and spatial AI.
Key Topics:
- Vision for Spatial AI: Moving beyond language to models that understand, generate, and simulate environments.
- Approaches: Comparing explicit 3D representations and generative models; noting no established recipe exists yet.
- Marble System: World Labs' system capable of generating navigable 3D worlds from images and other inputs.
- Challenges & Apps: Evaluating world models and their role in simulation, planning, agents, and robotics.
