Technical Definition
An alternative and more technically precise term for the phenomenon of AI hallucination, where an AI generates false or nonsensical information.
How it works
Confabulation is a synonym for hallucination in the context of AI, particularly Large Language Models (LLMs). It refers to the generation of information that is factually incorrect, nonsensical, or not grounded in the training data. While 'hallucination' is more commonly used, 'confabulation' is considered a more accurate descriptor because it implies the confident assertion of fabricated details, similar to how humans might confabulate memories.
