Quintais’s project will explore how EU law addresses the moderation of problematic generative AI (GenAI) content, aiming to protect freedom of expression. As tools like ChatGPT and Gemini raise risks such as disinformation and censorship, existing EU laws remain fragmented and unclear. Quintais will use legal analysis, empirical research, and normative theory to examine current regulation, provider practices, and foundational principles. By bridging gaps between platform and AI law, the project seeks to guide future regulation through a principled, rights-respecting framework. Its contributions include policy recommendations, novel empirical tools, and an interdisciplinary agenda for regulating GenAI content in the EU.
