Hallucination
A phenomenon where an AI model generates seemingly plausible but factually incorrect, nonsensical, or unverified information as if it were absolute truth.
Think of It Like This
Like a confident student who didn't study but convincingly invents an answer to pass an oral exam.
Hallucinations occur when a model prioritizes statistical probability over factual accuracy during generation. They are a significant hurdle for deploying AI in critical areas like healthcare or law. Mitigation strategies often involve grounding the model's responses using external knowledge bases.
