HINTBench: Horizon-agent Intrinsic Non-attack Trajectory Benchmark

Jiacheng Wang, Jinchang Hou, Fabian Wang +3

Existing agent-safety evaluation has focused mainly on externally induced risks. Yet agents may still enter unsafe trajectories under benign conditions. We study this complementary…

Safety-Utility Conflicts Are Not Global: Surgical Alignment via Head-Level Diagnosis

Wang Cai, Yilin Wen, Jinchang Hou +5

Safety alignment in Large Language Models (LLMs) inherently presents a multi-objective optimization conflict, often accompanied by an unintended degradation of general capabilities…
