100-word summary
Mastercard just trained a foundation model on billions of anonymized credit card transactions. The Large Tabular Model can predict future purchases and spot fraud patterns before they hit your account. It replaces thousands of single-purpose AI models with one flexible base that powers everything from fraud detection to loyalty rewards. The catch? It's internal only for now, available through APIs that let Mastercard teams build new tools on top. The model runs on Nvidia chips and Databricks, learning from more data types as it grows. One concrete use: hybrid fraud systems that combine the LTM with existing security tools to catch suspicious transactions faster than current methods.
