Core Viewpoint - The research suggests that Chain-of-Thought (CoT) reasoning in large language models (LLMs) may not represent true reasoning but rather a replication of patterns learned from training data, leading to fragility when faced with out-of-distribution tasks [2][10][37]. Data Distribution Perspective on CoT - The effectiveness of CoT is attributed to the "structured inductive bias" learned within the training distribution, indicating that the reasoning chains are merely reproductions of common patterns rather than genuine logical deductions [13][37]. - A theoretical framework is introduced to quantify the relationship between training and testing distributions, highlighting how distribution shifts can impact reasoning performance [15]. Experimental Findings on Generalization - In "task generalization," the model shows nearly 100% accuracy within the training distribution, but accuracy drops to 0.01% with slight distribution shifts, indicating a lack of true generalization [23]. - Supervised fine-tuning on a small amount of new data can restore performance, but this only expands the existing distribution boundaries without enhancing abstract generalization capabilities [24]. - In "length generalization," even minor changes in input sequence length significantly affect model performance, demonstrating a tendency to generate reasoning chains consistent with training lengths [26]. - The model is highly sensitive to format changes, with even minor alterations in input prompts leading to complete reasoning failures [28]. Universal Sensitivity to Distribution Shifts - The study finds that the sensitivity to distribution shifts is a common phenomenon across different sampling temperatures and model sizes, indicating that this issue is not isolated to specific models [31]. Practical Implications - In high-risk fields such as healthcare and finance, reliance on CoT for robust reasoning is cautioned against, as misleading reasoning chains can be more dangerous than outright incorrect answers [34]. - Current evaluation methods that depend on validation sets closely aligned with training distributions may overestimate model robustness, necessitating stricter out-of-distribution testing [35]. - While supervised fine-tuning can quickly enhance performance on specific tasks, it does not equip models with true abstract reasoning capabilities [36].

Group 2: Token Analysis - The study reveals a unique entropy distribution pattern during chain-of-thought reasoning, where over 50% of tokens have an entropy value below 0.01, while only 20% exceed 0.672 [9][10]. - High-entropy tokens serve as "logical connectors" in reasoning, while low-entropy tokens are often deterministic components, such as affixes or mathematical expressions [11]. - The team conducted experiments showing that increasing the temperature of high-entropy tokens improves reasoning performance, while lowering it decreases performance, underscoring the importance of maintaining high entropy in critical positions [13]. Group 3: Training Methodology - By focusing solely on the top 20% of high-entropy tokens during reinforcement learning training, the Qwen3-32B model saw significant performance improvements, with AIME'24 scores increasing by 7.71 points and AIME'25 by 11.04 points, alongside an average response length increase of approximately 1378 tokens [15][17]. - Similar performance enhancements were observed in the Qwen3-14B model, while the Qwen3-8B model maintained stable performance [16]. - Conversely, training with 80% low-entropy tokens led to a sharp decline in model performance, indicating their minimal contribution to reasoning capabilities [18]. Group 4: Implications and Generalization - The findings suggest that high-entropy tokens facilitate exploration of different reasoning paths, while low-entropy tokens may restrict this exploration due to their determinism [20]. - The advantages of training with high-entropy tokens become more pronounced with larger models, with the 32B model showing the most significant improvements [22]. - Models trained with high-entropy tokens also performed exceptionally well on out-of-domain tasks, indicating a potential link between high-entropy tokens and the model's generalization capabilities [22]. Group 5: Reinforcement Learning Insights - The research indicates that reinforcement learning with verifiable rewards (RLVR) does not completely overhaul the base model but rather fine-tunes it, maintaining a high overlap of 86.67% in high-entropy token positions even after extensive training [24][25]. - The study highlights that higher initial entropy in tokens correlates with greater increases in entropy during RLVR training, while low-entropy tokens remain largely unchanged [25]. - Discussions raised in the article suggest that high-entropy tokens may explain why reinforcement learning can generalize better than supervised fine-tuning, which tends to lead to memorization and overfitting [26][27].
