OpenAI CEO Sam Altman testified for the first time before the US Senate Judiciary Subcommittee on Privacy, Technology, and the Law at its "Oversight of A.I." hearing. Altman himself called for regulation, including licensing of AI models and a new government agency, alongside witnesses Christina Montgomery of IBM and Gary Marcus of New York University. An AI company chief asking to be regulated drew wide attention and marked a turning point in the US debate on AI regulation.
