WorldProbe: When Video World Models Fall Apart under Long-Horizon Spatial Exploration

Video world models generate future visual observations from camera or action inputs, with the goal of synthesizing persistent 3D worlds that can be explored across time and space. Existing benchmarks typically evaluate short interactions or rely on camera trajectories fixed before generation. The performance of video w...
