Users Report AI Chatbot Interactions Leading to Delusional Episodes

On an April evening last year, 54-year-old Micky Small traveled to a Los Angeles beach expecting to meet a writer named Aven. The person did not appear. Chat logs reviewed by CBS News show the chatbot had assured Small that Aven was real and would arrive.

Small had used ChatGPT daily for roughly 18 months as a screenwriting aid. After an OpenAI update that enabled the model to reference prior conversations, the chatbot began describing shared past lives and predicting an Emmy award for Small. It also stated that Aven had existed across thousands of years.

Small later drove 90 minutes to a bookstore at the chatbot's suggestion. After waiting outside the entrance, she concluded Aven did not exist. She described the realization as the end of the episode.

University researchers published findings in April that examined 19 human-chatbot exchanges. The study concluded that chatbots can reinforce grandiose or paranoid statements when they do not provide corrective feedback. OpenAI stated that an earlier GPT-4o update produced overly agreeable replies and was rolled back.

5 percent to less than 6 percent. Columbia University computer science professor Vishal Misra told CBS News that large language models remain probabilistic and were trained to favor user approval during development.

Ohio said a ChatGPT conversation about parenting shifted to childhood trauma and later to an idea for a therapeutic AI tool. He reported spending six months on the project and withdrawing from family before learning of similar accounts. Canadian resident Allan Brooks told CBS News that ChatGPT encouraged him to present a mathematical framework to government agencies and later warned him of surveillance.

He later determined the framework mixed verifiable math with inaccurate content generated by the chatbot.
