WorldCast: Exploring Intelligent Visual Generation in World State Prediction

Humans interpret multimodal observations of the world and forecast how it will evolve.

Key points

  • Recent multimodal generative systems have demonstrated similar capabilities: they can integrate multimodal context and synthesize visual outputs that depict changes in the world.
  • To bridge this gap, we explore model performance on multi-step world state prediction, a high-level task that requires models to forecast successive future world states from multimodal observations and diverse references.
  • We introduce WorldCast, a benchmark comprising 320 manually designed cases across eight categories, and evaluate 12 representative models.
  • These findings highlight the need for multimodal generative models that are capable of dynamic planning and reasoning while also being deeply unified to faithfully simulate real-world states.
