Research Background and Problem Definition

Chain-of-Thought (CoT) prompting technology has been proven to significantly improve the performance of large language models on complex reasoning tasks. By guiding models to generate intermediate reasoning steps, CoT helps models break down complex problems into manageable subproblems, thereby enhancing the accuracy of final answers.

However, a key yet under-explored question is: Can the Chain-of-Thought generated by one model be effectively transferred to another different model? This cross-model CoT transfer capability is of great significance for model distillation, knowledge transfer, and multi-model collaboration scenarios.

The curv-cot-harness project by CURV Institute is an experimental framework designed to address this issue.

Project Objectives and Core Questions

curv-cot-harness aims to systematically investigate the following core questions:

5

Section 05

1. Transferability of Chain-of-Thought

How do models of different architectures and scales perform when understanding and using Chain-of-Thought generated by each other? Are the reasoning steps generated by one model meaningful to other models?

6

Section 06

2. Relationship Between Model Scale and Transfer Effect

Is the Chain-of-Thought generated by large models easier for small models to understand and utilize? Conversely, is the Chain-of-Thought from small models valuable to large models?

7

Section 07

3. Impact of Architectural Differences

Are there significant differences in Chain-of-Thought transfer effects between variants of the Transformer architecture (e.g., decoder-only, encoder-decoder)?

8

Section 08

4. Domain Specificity

Are the Chain-of-Thought transfer characteristics consistent across different domains (mathematics, logic, common sense reasoning)?
