Key points

  • Benchmarks use a pipeline of task bank, test runner, model output, and grader to produce a score.
  • Scores can drift from reality via contamination (data leakage), saturation (ceiling effect), or gaming (agents finding shortcuts).
  • Trustworthy benchmarks require task isolation, process verification, and environmental controls.
  • When reading a model release, consider where each benchmark sits on the maturity curve.
