High-scale risk AI can qualify as a workflow case while its performance claims remain explicitly company-modeled and refresh-sensitive.
AI value · Fraud-detection model performance
Company-reported
Mastercard's initial modeling showed 20% average fraud-detection improvement.
Internal modeling, not audited production performance.
Before
Scores transactions from account, merchant, device, and purchase features. → Approves, declines, or challenges the transaction.
After
Analyzes entity relationships across a much larger graph and improves the risk score in under 50 milliseconds. → Uses the score with its own rules to approve, decline, or challenge.
Human boundary
Issuers decide approval, decline, challenge, and customer remediation.
Why it matters
A sub-50-millisecond model can enrich transaction risk before the issuing bank decides approval.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.

Work that left the path
Some manual relationship analysis for transaction-risk patterns
Human role before
Fraud teams designed rules and reviewed exceptions around transaction scores.
Human role after
Fraud teams govern thresholds, monitor drift and false positives, and investigate exceptions while the model enriches each score.
