The key transparency requirements set forth in the EU's AI Act have officially come into effect, signifying that the world's inaugural comprehensive legislation governing AI has entered its substantive implementation phase. According to these new regulations, interactive systems like chatbots are mandated to explicitly notify users of their non-human nature. Furthermore, images, videos, audio, and textual content that are generated or altered by AI must be distinctly labeled, along with the inclusion of machine-readable digital markers.
