Hallucination (General):
Experiencing things that aren’t really there, seeing, hearing, or feeling something that doesn’t exist in reality. Your brain creates sensory experiences without any external source.
Examples:
- Hearing someone call your name when you’re home alone
- Seeing a person or object that isn’t actually there
- Feeling something touch you when nothing is near you
- Smelling or tasting something that doesn’t exist
AI Hallucination:
When artificial intelligence confidently makes up information that sounds convincing but is completely false. The AI generates fake facts, citations, or details rather than admitting it doesn’t know something.
Examples:
- An AI inventing a research study that never existed
- Making up biographical details about a real person
- Creating fake statistics or data that sound legitimate
- Generating a nonexistent book title with a made-up author
Note:
An AI chatbot hallucinates more than a large model, and it also depends on how you trained your models more accurately you tained less they hallucinate.
