Problem Statement
TOPS Strategy
Experimental Results
Limitations
The paper investigates a critical issue in LLM reasoning: whether excessively scaling Chain of Thought (CoT) length can degrade performance, particularly in mathematical tasks. Existing o1-like models often generate excessive tokens for simple problems, leading to 'overthinking' and sometimes erroneous steps.
Our proposed Thinking-Optimal Scaling (TOPS) strategy involves three stages: Format Imitation, where the base model learns varied reasoning efforts from seed data; Reasoning Effort-Conditioned Generation, applying these efforts to generate diverse solutions; and Self-Improvement, where the model selects the shortest correct response for fine-tuning.
TOPS models, built on Qwen2.5-32B-Instruct, demonstrate superior performance over distillation-based models across math benchmarks (GSM8K, MATH500, AIME2024). They adapt reasoning depth, using fewer tokens for easier tasks and more for complex ones, achieving results comparable to the teacher model QwQ-32B-Preview.
Current analysis primarily focuses on mathematical reasoning. Future work will explore broader domains and delve into the impact of CoT length in reinforcement learning settings. The potential for erroneous intermediate steps in longer CoTs suggests that over-rewarding long, correct solutions might encourage inefficient reasoning paths.
Critical Finding: Excessive CoT Can Impair Performance
87.06% vs 86.89% Accuracy drop on GSM8K with longer CoT (LLaMA3.1-8B-Tag)Our research reveals that excessively long Chain of Thoughts can lead to a decrease in reasoning accuracy, especially on easier tasks like GSM8K. This highlights the need for optimal scaling rather than simply maximizing token length.

Case Study: Understanding CoT Degradation from Erroneous Steps
Our analysis shows that increasing reasoning effort can lead to a higher number and proportion of erroneous steps in CoT paths (Figure 4). Training models on these excessive erroneous steps negatively impacts reasoning abilities.
We found that applying loss masking specifically to wrong steps, rather than removing entire solutions, allows the model to learn error correction without direct exposure to the erroneous steps themselves.
