A new benchmark has been developed to assess how large language models (LLMs) perform with common French input variations, such as omitted apostrophes, diacritics, and keyboard typos. The study found that accuracy decreases and prediction reliability metrics like Brier score and negative log-likelihood increase as these input perturbations become more intense. While larger models generally show better accuracy under high-intensity variations, their probability predictions do not consistently improve with scale. The research also indicates that calibration temperatures from original inputs transfer well to these varied inputs, and combining calibration with input restoration further enhances performance. AI
