AI hallucinations about brands

From Search Visibility Wiki · By the · Published · Last reviewed · How we research

AI hallucinations about brands are false statements AI tools make about a company: wrong prices, features, founders or reviews. OpenAI researchers argue models hallucinate because training and evaluation reward guessing. Answers can also repeat outdated sources. Fix them by correcting the sources, publishing clear facts and reporting errors.

Why do AI tools hallucinate?

“Why Language Models Hallucinate” (September 2025) argues hallucinations persist because evaluations reward guessing over expressing uncertainty.[1] Even with retrieval, a 2023 audit found only 51.5% of sentences fully supported by citations.[2]

How do you fix brand hallucinations?

  1. Document the error: prompt, engine, date, cited sources.
  2. Fix your own pages and structured data.
  3. Correct third-party sources and profiles.
  4. Use the engine’s feedback tools.
  5. Re-test; see AI visibility checker.

Frequently asked questions

Can I sue over AI hallucinations?

That is a legal question; consult counsel.

How fast are corrections reflected?

Search-based answers can update when sources are recrawled; training data does not.

Do all engines hallucinate?

All LLM-based tools can.
