Benchmarks are an unreliable measure of difficulty

Summary

论文研究了基准测试中问题难度和框架方式如何影响模型训练分数的观测提升，指出许多基准隐性地加权了特定难度区域，其排行榜结论需谨慎解读，部分基准甚至覆盖不足难度轴，难以有效监控模型改进过程。

Very interesting paper on the way that benchmark question difficulty and framing affect the observed improvement in scores for model training. “Our results show that many benchmarks implicitly overweight certain difficulty regions, so their leaderboard conclusions should be interpreted with caution; others leave substantial portions of the difficulty axis un-covered, limiting their ability to monitor the model improvement process.” https://arxiv.org/pdf/2610.29927
