The UK Competition and Markets Authority (CMA) said on Thursday it would look at the underlying systems – or foundation models – behind AI tools. On the same day, the US government announced measures to address the risks in AI development, as Kamala Harris, the vice-president, met chief executives at the forefront of the industry’s rapid advances. AI development is dominated by the private sector, with the tech industry producing 32 significant machine-learning models last year, compared with three produced by academia. Companies that have agreed to participate include OpenAI, Google, Microsoft and Stability AI. The companies and their top AI developers are well aware of the risks posed by generative AI.
