Researchers have developed Marionette, a novel world model for interactive games that separates explicit state prediction from appearance synthesis. This approach models a 276-dimensional 3D world state, including articulated skeletons and trajectories, which is then used by a fixed renderer for geometry and a diffusion model for photorealistic appearance. Marionette demonstrates direct controllability of the predicted world state and allows for the repair of long-horizon inconsistencies, such as characters drifting too far apart or penetrating terrain, by imposing rules on the explicit state.

IMPACT This approach could enable more controllable and consistent AI agents in interactive environments by decoupling state prediction from visual synthesis.
