 ## Abstract
 
 Tree-of-Thought (ToT) Prompting, a fresh technique borrowing ideas from the Tree-of-Thoughts framework, broadens and enhances the well-established Chain-of-Thought prompting concept, thereby enabling Large Language Models, like ChatGPT, to exhibit superior reasoning abilities. This Tree-of-Thought Prompting technique permits Large Language Models to rectify their errors autonomously while progressively accumulating knowledge.
