# Evaluating Generative AI Use and Accuracy
Discuss how you decide whether generative AI belongs in a software product or workflow. Ground the answer in a project you understand, then cover appropriate and inappropriate use cases, how you define accuracy, and how you manage errors after launch.
### Constraints & Assumptions
- The system may produce fluent but incorrect output.
- Accuracy must be defined against the user task, not only a generic model benchmark.
- Sensitive data, latency, cost, and human review may affect the design.
### Clarifying Questions to Ask
- What consequence follows from a wrong answer, and can a person review it before action?
- Is the expected output factual, creative, classificatory, or a tool call?
```hint Begin with failure cost
The same model quality may be acceptable for drafting and unacceptable for an irreversible decision.
```
### What a Strong Answer Covers
- A clear task boundary and comparison with simpler approaches.
- Task-specific offline evaluation and representative test sets.
- Guardrails, retrieval or tool grounding where appropriate, and abstention.
- Production monitoring, feedback, versioning, and rollback.
### Follow-up Questions
- How would you evaluate a task with several acceptable answers?
- What would make you remove the model from the critical path?
Overview: Discuss prior generative-AI projects, when generative AI is an appropriate tool, useful application patterns, and how to evaluate and improve output accuracy.
