The Department for Science, Innovation and Technology (DSIT) has announced that 16 artificial intelligence (AI) tech companies have agreed to commit to develop AI safely. This marks a world first, as companies spanning the globe, including from the US, China and the Middle East, make this agreement on the opening day of the AI Seoul Summit (21 May 2024), building on the inaugural AI Safety Summit hosted by the UK in November 2023. The AI tech companies are to each publish safety frameworks on how they will measure risks of their frontier AI models, such as examining the risk of misuse of technology by bad actors, outlining when severe risks, unless adequately mitigated, would be 'deemed intolerable' and what companies will do to ensure thresholds are not surpassed. In extreme circumstances, the companies have also committed to 'not develop or deploy a model or system at all' if mitigations cannot keep risks below the thresholds. To assist in defining these thresholds, companies will seek input from trusted actors including home governments, before being released ahead of the AI Action Summit in France in early 2025.
