Hallucination

In the context of AI, "hallucination" refers to the generation of output that is not grounded in reality or fact. It occurs when an AI system produces content that is not supported by the input data it was trained on, leading to inaccurate or nonsensical results. This can happen when the model has not been properly trained or lacks sufficient data, or when it extrapolates beyond its capabilities.
