arXiv:2605.23652v1 Announce Type: new Abstract: On a 300-persona life-simulation benchmark, pcsp achieves compositional zero-shot persona identification up to 17x above chance, Spearman rho approx 0.73 semantic-behavioral alignment, and 22x faster inference than an LLM-as-policy baseline. Life simulation games require hundreds to thousands of non-player characters (NPCs) that behave consistently with distinct personalities while remaining controllable through designer-authored natural language. Existing methods fail on constraints like persona consistency, controllability, or real-time inferen
Advances in AI policy design and increased demand for scalable, consistent NPC behavior in virtual environments are driving innovation in this specific application.
This development allows for far more realistic and complex simulations in games and potentially other virtual spaces, demonstrating advanced AI agent capabilities.
The ability to generate and manage numerous NPCs with distinct, consistent, and controllable personalities using a single policy significantly lowers computational overhead and increases fidelity.

More immersive and dynamic virtual worlds become possible with a greater number of distinct, interacting AI characters.
This technology could extend beyond games to create more sophisticated virtual assistants, digital humans, or simulated populations for research and development.
The principles behind 'One Policy, Infinite NPCs' might lead to more generalized methods for controlling large numbers of diverse AI agents in complex environments with limited computational resources.
