🧠Researchers have introduced the concept of 'innovation' as a fundamental property that characterizes hallucination in large language models, showing it serves as an almost-complete mathematical characterization of when LLMs produce false information. The work extends prior research by Kalai and Vempala, establishing that innovation—the tendency to generate outputs outside training data—inevitably leads to hallucination with high probability, providing new theoretical bounds on hallucination rates.
