The Commission has procured 3 studies to support and inform the development of the Code of Practice on the marking and labelling of AI-generated content.

The 3 studies are:

These studies aim to provide a solid technical evidence base for the work on the Code of Practice. In particular, the studies assess existing and emerging techniques, their potential effectiveness, limitations, and practical applicability. This work helps ensure that discussions on marking and detection are grounded in the latest technical developments and take into account the specific characteristics of different types of AI-generated content.
