Use when designing or auditing the empirical core of a COLM paper — contamination analysis for evaluation data, fair baselines under matched prompting and compute, pinned model versions and decoding parameters, uncertainty over runs and samples, scaling coverage, and honest reporting of API-model comparisons.

# COLM Experiments

COLM's reviewer pool works on language models daily, which changes what "rigorous"
means: the failure modes they hunt are not missing error bars alone but the
LM-specific ones — leaked test sets, un-tuned baselines, drifting API models, and
decoding settings that quietly decide the result. Build the evaluation so those four
attacks fail.

## The four LM-specific attacks on your results

**1. Contamination.** Any public benchmark plausibly overlaps the pre-training data
of any recent model. For each evaluation set, either (a) run and report an overlap
analysis against known corpora, (b) use dated or freshly generated items and say so,
or (c) state explicitly that contamination could not be assessed and bound what it
