UnverifiedIn comparisons with optimizers using the same criterion, the hybrid method won 6, tied 41 and lost 19 of 66 Holm-corrected accuracy comparisons.68% similarUnverifiedRanked by question difficulty, persistence rate was 91.4% on the 60 questions that all models answered correctly, but only 73.5% on the 52 questions that at least one model got wrong, indicating that sycophancy tracks uncertainty.65% similarUnverifiedOn a test subset of 152 completely untouched questions, anchored hybrid retrieval achieved 42.11%, while the planner-guided method reached only 36.84%.64% similarUnverifiedIn a controlled experiment with eight paired generation blocks, the iterative program achieved success rates of 46.1% and 31.6% on unseen lengths n=13 and 15, respectively, while independently generated programs achieved only 19.5% and 3.1%.64% similarUnverifiedThe best-of-8 selection strategy refers to generating 8 candidate outputs for the same prompt and then picking the best, which can significantly improve evaluation scores but roughly increases inference cost by 8 times; comparing a system using this strategy with a single-sample system is not entirely fair.63% similar
