Tiered Agentic Oversight: A Hierarchical Multi-Agent System for Healthcare Safety

Yubin Kim, Hyewon Jeong, Chanwoo Park +9

Large language models (LLMs) deployed as agents introduce significant safety risks in clinical settings due to their potential for error and single points of failure. We introduce…
