From August 2026, an EU-wide AI regulation will come into force requiring the labeling of AI-generated content. However, a research team from the University of Bayreuth and Aalto University in Helsinki, Finland, has found that users of AI systems can no longer reliably recall after just one week whether content was generated by AI or not. The researchers presented their findings at the CHI conference, the most important and largest international conference in the field of Human–Computer Interaction.
