Your AI feature works in the demo.

It fails in production 3 weeks later. Nobody touched the model. Nobody changed the code.

The only thing that changed: the inputs got messier.

Here's the setup:

You're at a SaaS company. 50,000 support tickets a week. Your team builds an AI triage system — GPT-4o classifies each ticket into 6 categories (billing, bug, feature request, account access, security, other) so the right team gets it instantly.
