OccSim: Multi-kilometer Simulation with Long-horizon Occupancy World Models

ArXi:2603.28887v1 Announce Type: cross Data-driven autonomous driving simulation has long been constrained by its heavy reliance on pre-recorded driving logs or spatial priors, such as HD maps. This fundamental dependency severely limits scalability, restricting open-ended generation capabilities to the finite scale of existing collected datasets. To break this bottleneck, we present OccSim, the first occupancy world model-driven 3D simulator.
