arXiv:2606.03217v1 Announce Type: cross Abstract: Chain-of-thought (CoT) reasoning has become a widely used mechanism for eliciting multi-step reasoning in large language models by generating intermediate reasoning steps at inference time. Yet the scaling behavior of generalization with CoT depth remains poorly understood. To address this question, we study a theoretically solvable model of CoT for in-context weight prediction in linear regression, where test-time reasoning is represented as an iterative refinement of the weight-parameter estimate. Using tools from random matrix theory under h
The paper addresses a critical, poorly understood aspect of large language models (LLMs) scaling behavior, specifically the generalization and depth of Chain-of-Thought reasoning. This research appears as the widespread application of CoT in LLMs makes deeper theoretical understanding urgent.
This theoretical work provides foundational understanding of how CoT reasoning scales, which is crucial for optimizing and deploying more effective autonomous AI systems. Understanding CoT's scaling behavior directly impacts the development trajectory of advanced AI.
Our understanding of the theoretical limits and optimization pathways for advanced AI reasoning, particularly in multi-step problem-solving, is now enhanced. This could lead to more robust and predictable AI agent performance.
