WorldPlay2: Extending Real-Time Interactive World Models in Control and Horizon
WorldPlay2 combines hybrid controls, compressed memory, and Stable Forcing for real-time long-horizon world models.
WorldPlay2 is an interactive world model designed for real-time control and long-horizon consistency. Its factorized hybrid interface combines frame-aligned action control with semantic controls that separate scene appearance, character identity, and dynamic events. Historical context is compressed into memory tokens shared by an autoregressive student and a bidirectional teacher, enabling clip-wise distillation instead of scoring a full rollout. Stable Forcing initializes the student with a few-step strategy and uses full-rollout replay to preserve long-horizon quality.
- Hybrid controls separate appearance, identity, and semantic events
- Shared memory tokens compress history for student and teacher
- Clip-wise scoring avoids processing an entire long rollout
- Stable Forcing uses few-step initialization and full-rollout replay
- Authors report better generalization than existing methods

Interactive world models require responding in real time to versatile controls and maintaining long-horizon consistency. However, modeling heterogeneous controls remains difficult, while explosive contexts and unstable distillation impede achieving both long-horizon consistency and real-time responsiveness.
