Researchers have introduced Brittlebench, a new framework and evaluation pipeline designed to quantify the sensitivity of large language models (LLMs) to variations in prompts. This method aims to address the limitations of current static benchmarks, which may overestimate model performance by not accounting for real-world input variability. Brittlebench applies semantics-preserving perturbations to existing benchmarks, revealing that model performance can degrade by up to 12% and alter the relative rankings of models in a significant majority of cases.
