The European Commission has appointed a Scientific Panel and an Advisory Forum to support enforcement of the EU Artificial Intelligence (AI) Act. The Scientific Panel comprises 60 independent experts with experience in frontier AI, engineering, technical auditing and industrial and societal impact. Its work will focus on general-purpose AI models, systemic risks, model classification, evaluation methodologies and cross-border market surveillance. The Advisory Forum will provide technical expertise and advice on matters relating to the EU AI Act, including standardisation and implementation challenges, with members drawn from academia, civil society and industry, including small and medium-sized enterprises. Key EU agencies, including the EU Agency for Fundamental Rights and the EU Agency for Cybersecurity, as well as standardisation bodies, will have a permanent role in the forum. Both bodies will advise the Commission's AI Office and national authorities on the application of the rules, with members serving two-year terms.
