What separates an AI demo from a production feature
A demo proves a model can produce a compelling answer once. A product has to produce a useful, safe answer repeatedly, for real users, under real constraints.

Start with the failure modes
Before choosing a model or building an interface, write down how the feature can fail. It may hallucinate a policy, miss a document, expose data across accounts, become too slow, or cost more than the value it creates.
These are product requirements, not cleanup tasks. Each important failure mode needs a way to detect it, a fallback behaviour and an owner.
Build an evaluation set early
Collect representative questions, difficult edge cases and examples of unacceptable output. Run them repeatedly as prompts, retrieval logic and models change.
A small evaluation set grounded in real usage is more valuable than a large dashboard of generic benchmark numbers.
Make uncertainty visible
Production AI should not pretend to know. Cite sources where useful, show when evidence is weak and create a clean path to human review for high-impact decisions.
Operate it like software
Track latency, cost, retrieval quality, user corrections and failure categories. Version prompts and model settings. Plan what happens when a provider is unavailable.
The model is only one component. The dependable product is the entire system around it.
