TWIML AI podcast interviews Justin Johnson, co-founder of World Labs, on world models and spatial AI.
- Why it matters: many researchers see capabilities beyond language as a key frontier — models that understand, generate, and simulate environments.
- Approaches: explicit 3D representations vs. generative models; there is still no established recipe for building these systems.
- Marble: World Labs' Marble generates navigable 3D worlds from images and other inputs; evaluating world models remains hard.
- Vision: combining simulation, planning, and action to support interactive virtual environments and agents/robots operating in the physical world.
