Towards System 2 Reasoning in LLMs: Learning How to Think With Meta Chain-of-Thought

Violet Xiang, Charlie Snell, Kanishk Gandhi +11

We propose a novel framework, Meta Chain-of-Thought (Meta-CoT), which extends traditional Chain-of-Thought (CoT) by explicitly modeling the underlying reasoning required to arrive…
