## AI overview

IH-Challenge is a training dataset designed to improve frontier LLMs' instruction hierarchy, safety steerability, and robustness against prompt-injection attacks. The article explains how models should prioritize system, developer, user, and tool instructions according to their trust level, and describes reinforcement learning as a way to train this behavior.
