Häufig gestellte Fragen

Why do LLMs hallucinate?
Because they generate text by predicting the most probable word, not the most true word. They have no concept of truth — only statistical plausibility.
How to avoid hallucinations?
RAG (connecting AI to verified sources), human verification, and using tools like Perplexity (which cites sources) significantly reduce the risk.
