What is the biggest ongoing cost in maintaining a real-time AI fraud detection system?

The biggest ongoing cost is not the cloud compute, but the data engineering and human review team required for edge cases the model isn't sure about. This includes managing false positives (which can be 5-7% of good transactions) and maintaining a dedicated operations team as a permanent line item.
