Unlike a fixed video rendered from one prompt, interactive generative video accepts continuing inputs that influence future frames. A system may respond to movement controls, prompted events or changes in the simulated environment.
The difficult part is keeping objects, geometry and causality coherent over time while responding quickly. Long-running sessions also need stable state so earlier actions remain meaningful instead of the scene resetting or drifting unpredictably.

Interactive generative video lets viewer input affect scenes that an AI system creates during the experience. Messages, votes, or game actions can guide what the system generates next.
For example, viewers might vote for a character to enter a forest, and a later generated scene follows that choice. The response is not instant because some video may already be queued and new scenes take time to render.
