Dan Ho and coauthors wrote a policy brief, “The World Model and Spatial Intelligence Era: Governing AI Beyond Language”, published by HAI. This brief highlights the emergence of world models and outlines a first-of-its-kind governance and policy agenda for the technology.

Key Takeaways:

• World models are AI systems that build a working representation of an environment to predict how it changes in response to action. They could lower the cost of high-quality simulation, benefiting infrastructure planning, crisis response, experimentation, and embodied AI training.
• No existing benchmark gives policymakers an adequate basis to evaluate a world model for safety-critical deployment. Closing that gap requires public investment in measurement science.
• Policy built for existing AI-generated content and autonomous decision-making does not fully address the risk profile of world models. The distinctive question is whether a simulated environment matches physical reality closely enough to train or test another system or guide a real-world decision.
• The scarcest input is action-labeled interaction data — robot trajectories and fleet logs that cannot be scraped from the web, which risks concentrated control. Public datasets should be an explicit target of federally funded research.
• World models are dual use, with national security implications. By lowering the cost of capable autonomous systems, they could open military advantage to less-resourced entrants, making early leadership in world-model research, development, and governance an urgent national security priority.
