Researchers from several EU-funded projects on AI and disinformation that are carried out in dialogue with EDMO have joined forces and just published a new white paper. Its goal is to deepen understanding of the disinformation-generation capabilities of state-of-the-art AI, as well as the use of AI in the development of new disinformation detection technologies, along with the associated ethical and legal challenges. The authors conclude by revisiting the challenges and opportunities brought by generative AI in the context of disinformation production, spread, detection, and debunking.
