Description: In August 2024, ChatGPT is reported to have falsely claimed that Norwegian citizen Arve Hjalmar Holmen had killed his two sons and been sentenced to 21 years in prison. The fabricated response allegedly included specific details about the supposed crime, despite Holmen never being accused or convicted of any offense. The incident prompted a GDPR complaint for defamation and inaccurate personal data.

Variants
A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
