Justin Johnson is an American computer scientist and associate professor of electrical engineering and computer science at the University of Michigan, currently on partial leave. He is a co-founder of World Labs, a spatial-intelligence company launched in 2024 with Fei-Fei Li that develops AI systems for understanding and generating 3D environments. He is best known for foundational computer-vision research including Visual Genome, DenseCap, perceptual losses for real-time style transfer, and Mesh R-CNN, as well as co-instructing Stanford's widely viewed CS231n course on convolutional neural networks.
“I've taken a bunch of my own old captures that never worked before and then put them through the system... imagine angles that I never would have gotten from a traditional kind of like Nerf or Splat type reconstruction”
Source→“World Labs' first product, Marble, generates 3D worlds from multimodal inputs (text, image, multiple images) and enables interactive editing.”
Source→“While Marble is simultaneously a world model that is building towards this vision of spatial intelligence, it was also very intentionally designed to be a thing that people could find useful today.”
“Even going from Hopper to Blackwell, like the performance per watt is about the same... we're kind of already seeing like a scaling limit in terms of what is the performance per watt that we can get.”
