chatgpt hallucinations

ChatGPT hallucinations refer to instances where the AI generates confident but factually incorrect information. A notable example is the bixonimania hoax, where a researcher invented a fake eye condition and seeded it with clues that should have made the deception obvious. Despite this, chatbots including ChatGPT, Microsoft Copilot, Google Gemini, and Perplexity surfaced the fiction as if it were real. This episode highlights that AI confidence is not the same as accuracy, and that ChatGPT hallucinations can occur when the model retrieves or generates information based on unreliable sources. Understanding these limitations is important for users who rely on AI for research or decision-making.
