Logic-RL: Unleashing LLM Reasoning with Rule-Based Reinforcement Learning
Inspired by the success of DeepSeek-R1, we explore the potential of rule-based reinforcement learning (RL) in large reasoning models. To analyze reasoning dynamics, we use synthetic logic puzzles as training data due to their controllable complexity and straightforward answer verification. We make some key technical contributions that lead to effective and stable RL training: a system prompt that emphasizes the thinking and answering process, a stringent format reward function that penalizes outputs for taking shortcuts, and a straightforward training recipe that achieves stable convergence. Our 7B model develops advanced reasoning skills such as reflection, verification, and summarization-that are absent from the logic corpus. Remarkably, after training on just 5K logic problems, it demonstrates generalization abilities to the challenging math benchmarks AIME and AMC.

This section provides an overview of the advancements in Large Language Model (LLM) post-training, highlighting the remarkable reasoning abilities demonstrated by models like DeepSeek-R1. It emphasizes the critical need for controlled experimental frameworks to reliably reproduce these results, particularly focusing on addressing questions about reasoning emergence in smaller models, optimal training data structures, and methodological replication.
Details on the Logic-RL framework, covering data synthesis using procedurally generated Knights and Knaves (K&K) logic puzzles, which offer controllable difficulty and ease of reward verification. It outlines the rule-based reward modeling process, including a stringent format reward function and specific modifications to the REINFORCE++ algorithm for enhanced performance and stable convergence.
Exploration of key research questions, including the comparison of GRPO with other RL algorithms (REINFORCE++ and PPO), the impact of specific "thinking" tokens and language mixing on reasoning ability, the concept of an "Aha moment" during training, and the model's capacity for out-of-distribution (OOD) generalization. It also compares the generalization capabilities of SFT versus RL.
Discusses the limitations of the current study, primarily its reliance on a small-scale logic dataset, and outlines future work. This includes extending the approach to more diverse and complex datasets, exploring methods for transforming long responses into shorter formats, stabilizing RL training, investigating mixed-language reasoning, and relaxing formatting constraints for potentially more inventive internal representations.

Emergent Reasoning: Beyond Memorization
Logic-RL trained models develop advanced reasoning skills such as hesitation, self-verification, multi-path exploration, backtracking, summarization, and formula application. These behaviors are not explicitly trained but emerge naturally, leading to human-like problem-solving. For instance, the model can apply 'If P, then Q' logic without direct instruction, demonstrating true reasoning rather than mere recall.
