European Union negotiators clinched a deal Friday on the world’s first comprehensive artificial intelligence rules, paving the way for legal oversight of AI technology that has promised to transform everyday life and spurred warnings of existential dangers to humanity. Negotiators from the European Parliament and the bloc’s 27 member countries overcame big differences on controversial points including generative AI and police use of face recognition surveillance to sign a tentative political agreement for the Artificial Intelligence Act. “Deal!” tweeted European Commissioner Thierry Breton just before midnight. “The EU becomes the very first continent to set clear rules for the use of AI.” The result came after marathon closed-door talks this week, with the initial session lasting 22 hours before a second round kicked off Friday morning. Officials were under the gun to secure a political victory for the flagship legislation. Civil society groups, however, gave it a cool reception as they wait for technical details that will need to be ironed out in the coming weeks. They said the deal didn’t go far enough in protecting people from harm caused by AI systems. “Today´s political deal marks the beginning of important and necessary technical work on crucial details of the AI Act, which are still missing,” said Daniel Friedlaender, head of the European office of the Computer and Communications Industry Association, a tech industry lobby group.
