arXiv:2604.08872v2 Announce Type: replace Abstract: Many language tasks can be modeled as classification problems where a large language model (LLM) is given a prompt and selects one among many possible answers. We show that the classification error in such problems scales as a power law in the number of classes. This has a dramatic consequence: the prediction error can be reduced substantially by splitting the overall task into a sequence of smaller classification problems, each with the same number of classes ("degree"). This tree-structured decomposition models chain-of-thought (CoT). It ha
This research provides a theoretical underpinning for Chain-of-Thought (CoT) prompting, a technique already in practice, explaining its efficacy at a critical juncture for improving LLM performance.
Understanding the scaling laws of classification error and the benefits of task decomposition can significantly refine the development and deployment of advanced AI agents, leading to more robust and capable systems.
The theoretical justification for CoT moves it beyond an empirical observation, guiding more principled architectural design and prompting strategies for complex AI tasks.

Chain-of-Thought becomes a more widely adopted and optimized strategy for complex AI tasks.
AI agents demonstrate enhanced problem-solving capabilities across diverse domains due to improved task decomposition.
The development of AI systems accelerates as theoretical insights reduce the need for purely empirical tuning.
