Reproducible gains are performance improvements that survive comparison with strong baselines and controlled, repeatable evaluation. They count only when robustness travels across distribution shifts and new benchmarks, rather than ending as a single leaderboard win. section 7.6
When benchmark progress fails to travel
Progress on ARC-AGI-1 appeared rapid, but some of it reflected benchmark familiarity and overspecialized search. ARC-AGI-2 and ARC-AGI-3 sharpened the demand for evidence that transfers beyond one benchmark. section 7.6
