arXiv:2605.28554v1 Announce Type: new Abstract: Recent Tabular Foundation Models (TFMs) have demonstrated state-of-the-art predictive performance, often surpassing Gradient-Boosted Decision Trees (GBDTs). However, the trustworthiness of these models, particularly their uncertainty quantification, has been largely overlooked. We investigate this gap through an extensive study comparing TFMs, GBDTs, and classical baselines on the 112 datasets of the TALENT benchmark. Our results reveal a performance-uncertainty trade-off: although TFMs achieve the highest predictive performance, measured by AUC,
The rapid advancement and deployment of Tabular Foundation Models necessitate a deeper understanding of their reliability, especially as they move into critical applications.
This research highlights a crucial trade-off between predictive performance and trustworthiness in advanced AI models, which impacts risk assessment, regulatory frameworks, and practical deployment in sensitive domains.
The focus expands beyond mere predictive accuracy to include uncertainty quantification as a critical metric for model evaluation, pushing for more robust and transparent AI systems.
