Researchers tackle the challenge of designing LLM agents that can serve multiple users with competing interests and different authority levels simultaneously.

Most current LLM systems are optimized for single-user interactions, treating one dominant user's instructions as the sole source of authority and utility

As LLMs are integrated into team workflows and organizational tools, they must now handle multi-principal settings with conflicting objectives, information asymmetry, and privacy constraints

This arXiv paper (2604.08567) presents the first systematic study formalizing multi-user LLM agent interactions as a multi-principal decision problem

The research addresses unavoidable conflicts that arise when a single agent must balance the needs and preferences of multiple users with different roles and authority levels
