OMB Memorandum M-25-21: Accelerating Federal Use of AI through Innovation, Governance, and Public Trust
M-25-21 directs US federal agencies on how to govern and use AI. It requires agencies to designate Chief AI Officers, maintain AI governance boards, publish AI use-case inventories, and apply minimum risk-management practices to "high-impact" AI, including pre-deployment testing, AI impact assessments, ongoing monitoring, human oversight and training, and remedies for affected individuals. It replaced the 2024 memoranda with a greater emphasis on adoption and innovation while retaining core risk practices.
