arXiv:2606.12721v1 Announce Type: new Abstract: Inferring others' beliefs requires more than reading surface signals; it requires tracking who told them what, in what order, and how credibly. The Theory of Mind Utility (ToM-U) formalizes this epistemic state inference problem at the computational level of analysis, specifying what mentalizing computes and why without commitment to algorithmic or neural implementation. ToM-U achieves this by constructing Local Epistemic World Models (LEWMs) -- directed typed graphs that represent agents, state nodes, and the epistemic relationships among them -
The accelerating pace of AI development and the increasing complexity of AI agent interactions are driving the need for more sophisticated understanding of 'Theory of Mind' in AI systems. The proposed Theory of Mind Utility represents a formal step towards achieving this.
This work introduces a foundational computational framework for AI to infer and model the beliefs of other agents, moving beyond simple signal-reading to complex epistemic state inference. It is critical for the development of robust, ethical, and collaborative AI agents capable of understanding and navigating human and other AI intentions.
The formal specification of a 'mentalizing mechanism' introduces a standardized approach to AI's ability to model beliefs, potentially accelerating the development of more sophisticated AI agents. This moves AI research from 'what if' to 'how to' for complex social cognition.

AI systems gain a more nuanced ability to understand and predict the behavior of other agents, human or artificial.
This leads to the development of more effective and reliable AI agents capable of complex collaboration and negotiation.
Advanced AI agents with robust 'Theory of Mind' capabilities could profoundly reshape human-AI interaction, collapsing white-collar workflows and the SaaS layer.
