  1. Benchmarking Benchmark Leakage in Large Language Models (2024 · 73 citations)
    Large language models are often trained on undisclosed corpora that may include public benchmark data, sometimes on purpose.
  2. OlympicArena: Benchmarking Multi-discipline Cognitive Reasoning for Superintelligent AI (2024 · 56 citations)
    Existing exam-style benchmarks for LLMs and LMMs mostly test knowledge recall or simple concept application, and they usually grade only final answers.
  3. Rethinking Data Mixing from the Perspective of Large Language Models (2026)
    The paper asks how training data from different domains should be weighted when pretraining LLMs. It also asks whether human-assigned domain labels (e.g. C4, Wikipedia, ArXiv, Book) match what the model itself treats as distinct. The authors observe that per-sample gradients form clearly separated clusters by source…
