Hello Inc.'s Robotaxi Unit Releases HelloWorld Driving World Model

Hello Inc.'s robotaxi business released HelloWorld, a generative driving world model that builds driving data on demand and tests driving policies interactively. The roughly 2-billion-parameter model generates seven-camera video with conditional lidar output and supports editing objects, trajectories and weather.

• About 2 billion parameters, seven-camera views and conditional lidar output
• Users can edit vehicles, pedestrians and trajectories, or switch weather and time of day
• Plain-language descriptions can also steer scene generation
• Aims to fill gaps in rare long-tail driving data
