arXiv:2607.06401v1 Announce Type: new Abstract: World models -- internal simulators that learn the structure and dynamics of an environment -- have become one of the most actively debated concepts in AI. From model-based reinforcement learning and video generation to embodied robotics and ultimately, physical AI, researchers across AI subfields are building systems that they call "world models", yet there is no consensus on what a world model fundamentally is, what it should predict, or how it should be built. This perspective article provides a scientific definition of world models, discussio
The increasing prevalence and varied applications of 'world models' across AI subfields necessitate a unified definition to guide research and development, moving beyond ad-hoc interpretations.
A standardized definition for world models will consolidate fragmented research efforts, accelerate progress in advanced AI systems, and inform future regulatory and investment strategies.
The landscape of AI development, particularly in areas like embodied AI and reinforcement learning, will become more coherent and purposeful with a shared understanding of this foundational concept.
