Nvidia launches AI-driven fraud detection tool

Financial institutions are abandoning fragmented AI architectures in favor of unified transaction foundation models, and early results suggest the shift is paying off. Chip designer Nvidia launched its AI-driven Build Your Own Transaction Foundation Model tool today, Pahal Patangia , head of global industry business development and payments at Nvidia, told FinAi News . The tool allows FIs to train AI models on billions of proprietary transactions rather than relying on purpose-built models for each use case such as geographic transaction detection and unique transaction attempts.

Live deployments Digital bank Revolut , Mastercard , Stripe and Adyen are early adopters and are posting high efficiency gains from Build Your Own Transaction Foundation Model, according to Nvidia’s release today. Revolut, for example, built AI-driven tool PRAGMA with Nvidia and trained the model on 24 billion proprietary data points from 26 million users across 100 countries, Patangia said. The tool helped the London-based digital bank increase its fraud recall by 64.7%. “Recall in fraud detection is the percentage of actual fraud cases your model catches,” he said. “If a bank previously caught 40% of fraud and now catches 65%, the incremental 25 percentage points translate directly into recovered losses.” Industry benchmarks suggest raising fraud recall by even 10 points can prevent more than $2 million a year for every $1 billion in transaction volume, he said, adding that Revolut eliminated weeks, possibly months of feature engineering time for new use case deployed with the tool. Stripe has also seen success with the tool, with the payment company blocking close to $112 billion in fraud last year, achieving a 38% average reduction in fraud rates, Patangia said.
