OMB Memorandum M-25-21: Accelerating Federal Use of AI through Innovation, Governance, and Public Trust
Binding guidance for all federal agencies (including independent regulators) that replaces M-24-10: agencies must appoint Chief AI Officers, publish AI strategies and use-case inventories, and apply minimum risk-management practices (pre-deployment testing, impact assessments, human oversight) to 'high-impact AI'. Agencies had 365 days (to 3 Apr 2026) to document those practices and must stop using non-compliant high-impact AI.
Why it matters
Vendors selling AI into federal agencies should expect testing, documentation and monitoring requests for any use that is 'high-impact' (rights, benefits, safety, critical infrastructure).
