## FAQ

### How do LLM developers reduce hallucinations?

Grounded retrieval with citations, constrained structured outputs, and eval suites that score accuracy before every release.

### Should we fine-tune a model?

Often not at first. Good retrieval and prompting solve most cases; fine-tuning pays off for narrow, high-volume tasks or cost reduction.
