Twenty-eight countries including the US, UK and China have agreed to work together to ensure artificial intelligence is used in a "human-centric, trustworthy and responsible" way, in the first global commitment of its kind. From a report: The pledge forms part of a communique signed by major powers including Brazil, India and Saudi Arabia, at the inaugural AI Safety Summit. The two-day event, hosted and convened by British prime minister Rishi Sunak at Bletchley Park, started on Wednesday. Called the Bletchley Declaration, the document recognises the "potential for serious, even catastrophic, harm" to be caused by advanced AI models, but adds such risks are "best addressed through international co-operation." Other signatories include the EU, France, Germany, Japan, Kenya and Nigeria.

The communique represents the first global statement on the need to regulate the development of AI, but at the summit there are expected to be disagreements about how far such controls should go. Country representatives attending the event include Hadassa Getzstain, Israeli chief of staff at the ministry of innovation, science and technology, and Wu Zhaohui, Chinese vice minister for technology. Gina Raimondo, US commerce secretary, gave an opening speech at the summit and announced a US safety institute to evaluate the risks of AI. This comes on the heels of a sweeping executive order by President Joe Biden, announced on Monday, and intended to curb the risks posed by the technology.
