Italy's privacy regulator rescinded its temporary ban on ChatGPT after the chatbot's developer, OpenAI, implemented changes demanded by the regulator, the latest twist in the complex regulatory response to new artificial-intelligence technology. Italy's ban was one of the first nationwide measures restricting the use of ChatGPT since it exploded globally in popularity in recent months. The Italian Data Protection Authority ordered the ban late last month, saying that OpenAI had "no legal basis" for using the data it had amassed about Italian residents to train its algorithms and that it was too easy for children to access.
