The AI Office should encourage and facilitate the drawing up, review and adaptation of Codes of Practice, taking into account international approaches. All providers of general-purpose AI models could be invited to participate. To ensure that the Codes of Practice reflect the state of the art and duly take into account a diverse set of perspectives, the AI Office should collaborate with relevant national competent authorities, and could, where appropriate, consult with civil society organisations and other relevant stakeholders and experts, including the Scientific Panel, for the drawing up of the Codes. Codes of Practice should cover obligations for providers of general-purpose AI models and of general-purpose models presenting systemic risks. In addition, as regards systemic risks, Codes of Practice should help to establish a risk taxonomy of the type and nature of the systemic risks at Union level, including their sources. Codes of practice should also be focused on specific risk assessment and mitigation measures.
