Same Questions, Harder Test
TL;DR for operators When several models all score near the top of an internal multiple-choice suite, the benchmark may still contain useful information. The remaining problem can be the evaluation format rather than the questions themselves. The paper introduces answer pooling: combine the answer options from several related questions, then require the model to assign one candidate to each question without reusing candidates. The questions and correct labels do not change. Across eight benchmarks and eighteen models, every evaluated model scores lower under pooling, and model rankings move enough that the format can affect comparative decisions. ...
