The European Commission's guidelines for the AI Act mandate transparency in training data for general-purpose AI models, requiring public summaries detailing the data used. This has sparked debate over what constitutes “sufficiently detailed” information, balancing rights holders' needs for access against providers' interests in protecting strategic assets. A template to aid in compliance was released in January 2025, structured into sections covering model details, data sources, and processing aspects, with final guidelines expected by mid-2025. Legal disputes will ultimately shape the regulation's implementation and future AI standards globally.
