Contamination Map Methodology

Tabular foundation models

Which benchmark datasets could each model have seen during training? Every coloured square links to a verbatim quote from the model's paper, model card or repository. Grey means not enough has been disclosed to tell.

Rows are models, grouped by family; columns are benchmark datasets. Hover a square for the reason, click it for the evidence. Empty outlines mark benchmarks a model cannot take (e.g. image benchmarks for text-only models).
