Speedrunning Tabular Foundation Model Pretraining

A new community speedrun initiative has been launched for the nanoTabPFN model, aiming to accelerate pretraining processes for tabular foundation models. Participants modify a single-file training script to achieve a fixed ROC AUC target on a subsampled dataset using an NVIDIA L40S GPU, with the current best time recorded at 0.92 minutes, representing an 81x speedup over the previous baseline.
