About A Comparative Study on Reasoning Patterns of OpenAI's o1 Model

This paper, published on arXiv, presents a comparative study of OpenAI's o1 model against existing test-time compute methods (such as Best-of-N, Step-wise Best-of-N, Agent Workflow, and Self-Refine) using GPT-4o as a backbone across math, coding, and commonsense reasoning benchmarks. The study finds that o1 achieves superior performance on most datasets, identifies limitations in reward models and search space for response diversity methods, and highlights the advantage of domain-specific system prompts in Agent Workflow over Step-wise BoN. It also summarizes six reasoning patterns observed in o1 and provides detailed analysis on several reasoning benchmarks.

FAQ

What methods were compared with OpenAI o1?
The study compares o1 with four test-time compute methods: Best-of-N (BoN), Step-wise Best-of-N, Agent Workflow, and Self-Refine, all using OpenAI's GPT-4o as a backbone.
On which benchmarks was the comparison conducted?
The evaluation was performed on general reasoning benchmarks covering three domains: math, coding, and commonsense reasoning.
What are the main findings regarding response diversity methods?
For methods that search diverse responses (e.g., BoN), both the capability of the reward model and the search space limit the upper boundary of performance.
How does Agent Workflow compare to Step-wise BoN?
Agent Workflow achieved better performance than Step-wise BoN due to the use of domain-specific system prompts that allow for better reasoning process planning.
