AI Hallucination Detection

AI hallucination detection encompasses the methods, tools, and techniques used to identify when an AI model generates false, fabricated, or unsupported information. Detection approaches range from automated fact-checking against knowledge bases and cross-referencing multiple model outputs to specialized classifier models trained to flag likely hallucinations based on confidence patterns and linguistic cues.

Example

A medical AI generates the claim "Aspirin was first synthesized in 1897 by Felix Hoffmann at Bayer." A hallucination detection system cross-references this against a medical knowledge base, confirms the claim is accurate, and flags it green. For another claim about a non-existent clinical trial, the system finds no supporting evidence and flags it red for human review.
