I’ve noticed this pattern across teams working on deep learning systems: models look solid during training and validation, metrics are strong, loss curves are clean—and confidence is high. But once the model hits real users, things start to feel off. Predictions become less stable, edge cases show up more often, and performance degrades in ways that aren’t immediately obvious. Nothing is “broken” enough to trigger alarms, yet the model no longer behaves like the one we evaluated offline.
