Short Answer
When AI generates false or misleading information that appears plausible.
Hallucination occurs when AI models generate information that sounds plausible but is factually
incorrect or completely fabricated. This is a significant challenge in AI systems and can lead to
misinformation and reduced trust.
Common causes of hallucination:
- Training data issues: Inconsistent or incorrect training data
- Context limitations: Insufficient context for accurate responses
- Model limitations: Inherent limitations in model understanding
- Prompt ambiguity: Unclear or contradictory instructions
- Overconfidence: Model generating beyond its knowledge
