Hello Inc.'s robotaxi unit releases HelloWorld, a driving world model for scene generation

Hello Inc.'s robotaxi business released HelloWorld, a generative driving world model with about 2 billion parameters, announced October 12 along with an arXiv paper and project page.

The model edits vehicles, pedestrians and trajectories, generates multi-view camera video for seven cameras with conditional lidar output, and accepts plain-language scene descriptions.

The company has not said when or how it will use the model in its vehicle testing programs.
