What is a language model hallucination? America.gov case study.
Language model hallucinations are false or fabricated outputs the AI generates with confidence, even when unsupported by training data. America.gov's new chatbot (powered by Gemini and Grok) simplifies government navigation but risks sending users to non-existent agencies or procedures if the model invents facts.
WHY IT MATTERS
Banks and fintech platforms deploying LLM-powered customer service face similar risk: hallucinated regulatory guidance, account procedures, or fee structures erode trust and create compliance liability.
