This article analyzes a latest research from Tencent AI Lab and Shanghai Jiao Tong University, which proposes an efficient solution to the "overthinking" problem that exists in large language models (LLM), especially in o1-like models. plan. The so-called "overthinking" means that the model consumes too many computing resources and produces redundant reasoning steps when dealing with simple problems. This research effectively reduces the model's token usage by introducing new evaluation indicators and self-training methods, while maintaining or even improving the accuracy of the model, providing new ideas for improving the efficiency and scalability of LLM.
In recent years, the rapid development of large language models (LLM) has brought great changes to various fields, but its computational efficiency problem has become increasingly prominent. This article details the research results on the "overthinking" phenomenon of o1-like models, including the proposed new efficiency evaluation indicators and optimization methods based on self-training. Through experimental verification on multiple data sets, this study confirmed the effectiveness of its method and provided valuable experience for solving the efficiency problem of LLM. This research not only reduces the computational cost of the model, but also improves the interpretability of reasoning, making it more practical in resource-constrained scenarios. In the future, similar research will continue to promote the development of LLM technology in a more efficient and sustainable direction, laying a solid foundation for the widespread application of artificial intelligence.
