A new paper questions the reliability of temporal signals in detecting benchmark contamination for large language models. Researchers found that the way benchmark questions are phrased significantly impacts whether performance decay appears over time. LLM-generated questions can mask contamination that is evident with simpler question formats, suggesting current detection methods may be insufficient for accurate AI evaluation. AI
