ANIMASK: What the Model Contributes to Role Play in Simulated Story Worlds

Xiucheng Zhang, Zhuoning Xu, Hanjun Luo, Yankai Chen et autres

When a language model plays a character, the observed behavior reflects both the assigned persona and the default dispositions of the actor model itself. Existing evaluations test persona fidelity or model defaults in isolation, but neither says, at a specific choice with …

MasDrift: Benchmarking Authorization Preservation Across Multi-Agent Architectures

Zhuoning Xu, Xiucheng Zhang, Hanjun Luo, Yingbin Jin et autres

Multi-agent systems (MAS) decompose long-horizon tasks across supervisors and subagents, but delegated goals do not necessarily carry their original authorization boundaries. Existing safety benchmarks mainly study adversarial compromise, while work on constraint drift lacks controlled architecture-level evaluation. We introduce MasDrift, a benchmark …

ACKnowledge: A Computational Framework for Human Compatible Affordance-based Interaction Planning in Real-world Contexts

Z.Y. Pan, Xiucheng Zhang, Zisu Li, Zhenhui Peng et autres

Intelligent agents coexisting with humans often need to interact with human-shared objects in environments. Thus, agents should plan their interactions based on objects' affordances and the current situation to achieve acceptable outcomes. How to support intelligent agents' planning of affordance-based interactions compatible …
