World Labs scores A on the Alion truth index (A is best, E worst), measured over 11 open roles re-checked against its own hiring board: 0% look like ghost listings, 0% have gone stale and 0% are the same role posted again. Its roles close in a median of 208 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
World Labs is a spatial intelligence laboratory building large world models that generate and reason about three dimensional environments. Founded by the computer vision researcher Fei-Fei Li with collaborators from Stanford and Google, it argues that language alone cannot give machines an understanding of physical space. The company demonstrated systems that turn a single image into an explorable three dimensional scene and raised over a billion dollars in valuation within its first year; its team includes leading researchers in computer vision, graphics and generative modelling.
