World Labs Atlas turns three iPhone photos into a bullet-time flythrough that once needed hundreds of cameras, the team told a16z.
It reframes world models as new view prediction. Not next token. Not next frame.
Atlas is the second generation model from World Labs, the two-and-a-half-year-old startup led by Fei-Fei Li with Justin Johnson and NeRF creator Ben Mildenhall. Marble, its first model, forced everything through Gaussian splats. Atlas makes the view itself the primitive.
How World Labs Atlas actually works
Every input image carries its 3D camera pose, so the model treats images as spatial context rather than loose references you argue with via text. Think of it like pinning photos to an exact map, then asking for the view from any empty point on that map.
That lets one multimodal backbone output RGB plus depth for any pose you request, doing reconstruction of what was seen and generation of what was not in the same pass.
