arXiv:2602.07253v2 Announce Type: replace Abstract: Detecting hallucinations in large language models is a critical open problem with significant implications for safety and reliability. While existing hallucination detection methods achieve strong performance in question-answering tasks, they remain less effective on tasks requiring reasoning. In this work, we revisit hallucination detection through the lens of out-of-distribution (OOD) detection, a well-studied problem in areas like computer vision. Treating next-token prediction in language models as a classification task allows us to apply
The proliferation of Large Language Models (LLMs) across various applications necessitates robust methods for identifying and mitigating their inherent tendency to 'hallucinate,' especially as deployment scales and tasks become more complex.
Improving hallucination detection is critical for the safe and reliable deployment of AI, particularly in high-stakes reasoning tasks, directly impacting trust and adoption of advanced AI systems.
Approaches to hallucination detection are evolving from task-specific methods to more generalized, theoretically grounded techniques borrowed from out-of-distribution detection, promising more scalable and robust solutions.
