Model Laundering Vs Benchmark Contamination?
5.9BRAINROT SCOREMODEL LAUNDERING— ORIGIN, MEANING & USAGE
Model Laundering Taking a model built substantially on another company's proprietary weights or outputs and rebranding, fine-tuning, or repackaging it enough to obscure that underlying origin, presenting it as an independently developed model.
EXAMPLE USAGE
"The benchmark outputs were nearly identical to the other lab's model, community's calling it model laundering."
BENCHMARK CONTAMINATION— ORIGIN, MEANING & USAGE
Benchmark Contamination When a model's training data accidentally (or not-so-accidentally) includes the actual questions and answers from a benchmark it's later evaluated on, inflating its score without reflecting genuine improved capability.
EXAMPLE USAGE
"Turns out that shockingly high score was just benchmark contamination, the test questions were sitting in the training set."
MODEL LAUNDERING VS BENCHMARK CONTAMINATION
