AI Hallucination
Definition
AI Hallucination occurs when a generative AI system produces output that is plausible-sounding but factually incorrect or fabricated. Hallucinations are a structural feature of probabilistic AI, not a bug.
Why it matters
The business case for AI Hallucination.
Hallucinations have caused real-world business losses, including notable cases at major airlines and financial firms. In any operational context, hallucination risk must be designed out, not hoped against.
Related terms in Deterministic AI
Deterministic AI
Deterministic AI produces the same output for the same input, every time. Unlike probabilistic AI, deterministic systems deliver consistent, predictable, auditable outcomes that enterprise operations can rely on.
Probabilistic AI
Probabilistic AI generates outputs based on statistical likelihoods. The same input may produce different outputs across runs. Most large language models are probabilistic by design.
Generative AI
Generative AI is a class of probabilistic AI that creates new content, text, images, code, audio, based on patterns learned from training data. ChatGPT, Claude, and Midjourney are generative AI systems.
Explainable AI (XAI)
Explainable AI refers to AI systems whose decisions and outputs can be understood and traced by humans. XAI is critical for governance, compliance, and trust.
Auditable AI
Auditable AI produces a complete, verifiable record of every decision made and every input that influenced it. Auditable AI is a structural property of the architecture, not a feature added on later.
