Multics: Generative Multi-Player World Model with Hierarchical Communication
Multics claims a communication design that lets multi-player video worlds scale beyond the player count seen in training.
The paper proposes a hierarchical setup where players communicate through player, group, and global levels instead of every player attending to every other player directly. Group tokens aggregate locally relevant player information, while global tokens handle cross-group exchange. The authors say dynamic grouping based on recent camera trajectories keeps related players connected and limits unnecessary communication. In experiments, Multics reports state-of-the-art results for 4- and 6-player settings and inference generalization from 4-player training to 6, 8, and 10 players without retraining.
