IBM researchers have introduced BenchDrift, a method to evaluate the sensitivity of AI models to problem rephrasing. This technique generates variations of benchmark questions across linguistic, pragmatic, and structural axes while keeping the answer constant, then measures how correctness changes. The findings indicate that phrasing sensitivity persists even in advanced models, with top-performing models on benchmarks like GSM8K, MMLU, and MATH-Hard showing the greatest dependence on specific wording.

IMPACT Highlights the need for more robust AI evaluation methods that account for linguistic variations, potentially influencing future benchmark design and model training.
