Core Viewpoint - The article discusses the emergence of the Deep Think with Confidence (DeepConf) method, which enhances the inference efficiency and performance of large language models (LLMs) by dynamically filtering low-quality inference trajectories using internal confidence signals during the inference process [1][5]. Group 1: DeepConf Methodology - DeepConf addresses the limitations of existing methods by utilizing model internal confidence signals to filter out low-quality inference trajectories, thereby improving both inference efficiency and performance [1][10]. - The method can be seamlessly integrated into existing service frameworks without requiring additional model training or hyperparameter tuning, making it user-friendly for developers [8][10]. - DeepConf operates in both offline and online modes, allowing for flexibility in application depending on the use case [8]. Group 2: Performance Metrics - In offline mode, DeepConf@512 achieved a 99.9% accuracy on the GPT-OSS-120B model, significantly surpassing the traditional majority vote accuracy of 97.0% [10]. - In online mode, DeepConf can reduce the number of generated tokens by up to 84.7% compared to full parallel inference while simultaneously improving accuracy, effectively balancing performance and efficiency [10]. Group 3: Contributors and Research Background - Jiawei Zhao, a research scientist at Meta FAIR and a Caltech PhD, focuses on optimization methods for LLMs and deep learning [5][6]. - Yichao Fu, a PhD student at UCSD, specializes in LLM inference optimization and has contributed to multiple research projects aimed at improving LLM scheduling and breaking sequential dependencies in inference [8][10].

Core Insights - DeepConf, developed by Meta AI and UC San Diego, enables large models to monitor confidence levels in real-time during inference, dynamically eliminating low-confidence paths and weighting high-confidence paths for improved accuracy and efficiency [1][8][9] - At the AIME 2025 competition, DeepConf achieved a remarkable 99.9% accuracy using open-source models without external tools, while reducing token generation by 85% [2][4][19] Performance Metrics - DeepConf demonstrated an average accuracy improvement of approximately 10% across various models and datasets [10][19] - The method significantly reduced token generation, achieving a reduction of up to 85% while maintaining high accuracy [10][21] Methodology - The core idea of DeepConf is to filter inference paths based on confidence signals, balancing quality answers with efficiency [8][9] - DeepConf operates in two modes: offline and online. In offline mode, it evaluates completed inference paths, while in online mode, it monitors confidence in real-time to terminate low-quality paths [14][31] Voting Mechanism - DeepConf employs a confidence-weighted majority voting system, where the contribution of each inference path to the final decision is weighted by its confidence level [29][30] - The method filters out the lowest confidence paths before voting, ensuring that only high-confidence paths contribute to the final answer [15][30] Implementation and Compatibility - DeepConf is compatible with existing models without requiring additional training or hyperparameter tuning, allowing for easy deployment with minimal code [10][21] - The system can be integrated into vLLM with approximately 50 lines of code, making it accessible for various applications [10] Research and Development - The research team, led by Yichao Fu at UC San Diego, focuses on optimizing algorithms and systems for large language models (LLMs) to enhance their reasoning processes [47]
