Core Insights - The article discusses the development of a new benchmark called UQ (Unsolved Questions) to evaluate the capabilities of large language models, focusing on unsolved problems that reflect real-world challenges [2][3][5] - UQ consists of 500 challenging questions sourced from the Stack Exchange community, designed to assess reasoning, factual accuracy, and browsing capabilities of models [3][8] - The study highlights the limitations of existing benchmarks, which often prioritize difficulty over real-world applicability, and proposes a continuous evaluation method through community validation [1][5] Group 1 - UQ is a test set of 500 unsolved questions covering various topics, including computer science, mathematics, and history, aimed at evaluating model performance in a realistic context [3][8] - The selection process for UQ involved multiple filtering stages, reducing an initial pool of approximately 3 million questions to 500 through rule-based, model-based, and manual reviews [10][11] - The best-performing model in the UQ validation only succeeded in answering 15% of the questions, indicating the high difficulty level of the benchmark [5][7] Group 2 - The UQ validation process employs a composite verification strategy that leverages the strengths of different models to assess candidate answers without requiring standard answers [14][26] - The study found that using a composite validator significantly reduces self-bias and over-optimism in model evaluations, which is a common issue when models assess their own performance [24][25][26] - Results showed that a stronger answer generation model does not necessarily correlate with better answer validation performance, highlighting the complexity of model capabilities [27][28]
