Overworld Shares Video of Model Lacking Physics

Overworld, an AI startup formerly known as Wayfarer Labs, posted on X that its real-time diffusion world models show an emergent lack of physical understanding. The post includes a 3-second video of a simple 3D-rendered room with a brown table, brown chair on a gray rug, wooden floor, gray walls, and a four-paned window. The company builds interactive simulations meant to run locally on consumer hardware and used the clip to point out the model's shortcomings in handling physics.
