In May 2023, key AI CEOs, including Sam Altman, Demis Hassabis, and Dario Amodei, met U.K. Prime Minister Rishi Sunak in London to discuss AI risks following the success of ChatGPT. The U.K. subsequently launched the AI Safety Institute (AISI) to preemptively test new AI models' safety, funded with £100 million, making it the most advanced governmental AI safety initiative globally. Despite achieving early access agreements with AI companies, the AISI has faced challenges in acquiring full model access, impacting comprehensive evaluations. Political shifts and partnerships with a less funded U.S. counterpart highlight ongoing struggles in effectively regulating and influencing AI development.
