MLE-bench uses 75 Kaggle competitions as offline ML engineering benchmarks

MLE-bench evaluates ML engineering agents on 75 curated offline Kaggle competitions, testing model training, dataset preparation, experiment execution, and submission to grading scripts. Kaggle public leaderboards serve as human baselines. The best-performing setup—o1-preview with AIDE scaffolding—reached at least Kaggle bronze-medal level in 16.9% of competitions.
