UnpredictaBench - Shuffling: leaderboard
Metric: KS@100 (%): share of the 19 Shuffling problems (random orderings of items) for which 100 samples from the model (100 independent calls at temperature 1.0, reasoning effort none, up to 5 retries for a parseable answer) are not rejected by a two-sample Kolmogorov-Smirnov test against ground-truth samples at p < 0.0001; higher is better. Source: arxiv.org. Saturation forecast: Around 2037. 20 models tracked.
