ICML'24: Proceedings of the 41st International Conference on Machine LearningArticle No.: 921, Pages 22895–22907We argue that auto-regressive LLMs cannot, by themselves, do planning or self-verification (which is after all a form of reasoning), and shed some light on the reasons for misunderstandings in the literature. We also argue that LLMs should be viewed as ...
