A Norwegian man has lodged a complaint against OpenAI after ChatGPT falsely claimed he had murdered his two sons and was serving a 21-year prison sentence.

Arve Hjalmar Holmen, who has never been accused of any crime, says the chatbot's response was deeply damaging, leading him to seek action from the Norwegian Data Protection Authority.

Digital rights group Noyb, representing Holmen, argues the incident violates European data protection laws regarding the accuracy of personal data.

The error highlights a growing concern over AI 'hallucinations,' where chatbots generate false information and present it as fact.

Holmen received the incorrect response when searching for his own name, with ChatGPT fabricating a detailed and defamatory account of a crime that never occurred. Although the chatbot carries a disclaimer about potential inaccuracies,

Noyb insists this is not enough, arguing that spreading false information cannot be justified by a simple warning label.

AI-generated hallucinations have plagued multiple platforms, including Apple and Google, with some errors being bizarre but others causing real harm.

Experts remain uncertain about the underlying causes of these inaccuracies in large language models, making them a key focus of ongoing research.

While OpenAI has since updated ChatGPT's model to incorporate current news sources, the case raises questions about accountability and the transparency of AI-generated content.
