# Autoregressive World Model

Atlas is an autoregressive world model that previously took tens of seconds to minutes to produce a generated video, so users planned camera paths cautiously. The newly released Frameboy research preview serves a highly optimized Atlas variant from cloud GPUs and streams frames to the browser at up to 15 fps, updating the view continuously as the camera moves. The demo can generate scenes from a single image or text caption and retains and improves novel view synthesis from multiple images, but it must run on a powerful cloud GPU server and costs more than local rendering.

Driving 3D world models often treat geometry-foundation-model features as future states, yet those features shift with camera viewpoint, so the model must predict scene evolution and camera motion at once. GeoState compresses multi-view features into a view-decoupled scene state that a camera ray queries only at decoding, while camera motion is modeled separately. On Waymo it beats compared world models at every reported horizon and transfers zero-shot to KITTI and nuScenes.
