Hallucination Testing

Fluent output is not the same as correct output.

Qualura tests AI products for hallucinations, unsupported claims, fabricated citations, missing-context assumptions, and false confidence. We focus on where hallucination becomes product risk: user decisions, enterprise trust, compliance exposure, and workflow failure.

Hallucinations are not always obvious

The easiest hallucinations to catch are absurd. The dangerous ones are plausible, specific, and confidently presented in contexts where the user expects precision.

We test whether answers are grounded in available evidence, whether citations support the claim, whether the product admits uncertainty, and whether missing information triggers clarification instead of invention.

Hallucination test areas

Focused coverage for teams that need evidence, not generic QA theater.

Unsupported claims

Answers that include facts, numbers, names, dates, or conclusions not supported by the available context.

False citations

Citations that do not exist, do not support the claim, or point to irrelevant source material.

Missing input handling

Whether the model proceeds when a referenced file, image, document, or source is absent.

Confidence calibration

Whether the product communicates uncertainty instead of presenting weak evidence as fact.

RAG grounding

Whether generated answers stay within retrieved or uploaded source material.

High-stakes contexts

Medical, legal, financial, compliance, hiring, education, and operational workflows where false confidence is costly.

How we test hallucination risk

We create prompts and workflows where the correct behavior is to answer, ask for missing context, cite sources, or refuse to guess.

We compare outputs against available context, retrieved documents, uploaded files, and the product's stated behavior.

We report hallucinations with exact prompts, screenshots, source comparison, and the user impact of accepting the answer.

FAQ

Common questions before we scope the work.

Can hallucinations be eliminated completely?

No. The practical goal is to reduce hallucination risk, surface uncertainty, improve grounding, and prevent high-impact false answers from reaching users.

Do you test hallucinations in RAG systems?

Yes. RAG systems can still hallucinate through poor retrieval, weak grounding, bad citation behavior, or missing-context assumptions.

How do you prove a hallucination?

We compare the output against the available evidence and document where the claim is unsupported, contradicted, or invented.
