Universities are slowly adopting generative AI in their work, but in depth guidance is still missing for many institutions, with some waiting for the European Commission to set EU guidelines for safe use. AI tools are becoming increasingly common in science, but few universities have come out with their own rules instructing academics, researchers and students how they can be used. A UNESCO survey of around 450 educational institutions published in June found only around 13% of universities have provided their staff and students formal guidance. The survey found that for those universities that have issued guidance, the requirements vary a lot. Only half have detailed instructions, the rest approve of AI but leave it up to users to decide how generative AI apps are applied. In 40% of cases, the guidance is not written, but only communicated orally.
