# How do you reduce AI hallucinations in customer support?

Reduce AI hallucinations in customer support by grounding every answer in current, approved company data, requiring the AI to cite its sources, instructing it to say it doesn't know and hand off when information is missing, limiting it to defined topics, keeping knowledge accurate, and testing changes against a set of real questions before release.

## Causes and fixes

| Cause | Fix |
|---|---|
| No relevant data retrieved | Better retrieval, more complete knowledge |
| Stale content | Live sync with source systems |
| Missing relationships between records | Connected data such as a knowledge graph |
| Over-eager instructions | Allow "I don't know" and handoff |
| Open-ended scope | Restrict to supported topics |
| Untested changes | Evaluation sets before release |

## Monitor in production

Sample conversations weekly, track answers flagged as wrong, and add every failure to your evaluation set.

## FAQ

### What is an AI hallucination?

When an AI produces a confident answer that is false or not supported by its sources.

### Can hallucinations be eliminated?

Not entirely, but grounding, citations, scope limits and testing reduce them sharply.

### Does RAG stop hallucinations?

It reduces them by giving the model facts, but poor retrieval or missing data can still lead to errors.
