Cognitive Behaviors that Enable Self-Improving Reasoners, or, Four Habits of Highly Effective STaRs

Kanishk Gandhi, Ayush Chakravarthy, Anikait Singh +2

Test-time inference has emerged as a powerful paradigm for enabling language models to ``think'' longer and more carefully about complex challenges, much like skilled human experts…

Just Enough Thinking: Efficient Reasoning with Adaptive Length Penalties Reinforcement Learning

Violet Xiang, Chase Blagden, Rafael Rafailov +4

Large reasoning models (LRMs) achieve higher performance on challenging reasoning tasks by generating more tokens at inference time, but this verbosity often wastes computation on…

Big-Math: A Large-Scale, High-Quality Math Dataset for Reinforcement Learning in Language Models

Alon Albalak, Duy Phung, Nathan Lile +8

Increasing interest in reasoning models has led math to become a prominent testing ground for algorithmic and methodological improvements. However, existing open math datasets eith…

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…

Generative Reward Models

Dakota Mahan, Duy Van Phung, Rafael Rafailov +6

Reinforcement Learning from Human Feedback (RLHF) has greatly improved the performance of modern Large Language Models (LLMs). The RLHF process is resource-intensive and technicall…
