What is a Fabricated Content AI Hallucination?

A Fabricated Content AI Hallucination is when an artificial intelligence model generates entirely new, non-existent content—such as detailed narratives, source materials, or complex entities—and presents it as real and pre-existing. Fabricated Content is one type of AI Hallucination.

• Chance of Occurrence: Variable (more likely with less represented knowledge).
• Consequences: Severe misinformation, legal liabilities (e.g., wrongful accusations), wasted time verifying non-existent information, and significant damage to reputation.
• Mitigation Steps: Enhance fact-checking mechanisms; use RAG for grounding; train models to express uncertainty when information is scarce; implement post-generation filters for consistency checks.
