It describes risks and suggested actions across the AI lifecycle, organized around the framework's Govern, Map, Measure, and Manage functions rather than prescribing one implementation for organizations.

• European AI Act enters into force

  The European Commission announced that the EU AI Act entered into force. The regulation uses a risk-based approach and creates obligations on different timelines, including transparency, governance, and general-purpose AI provisions. Its announcement describes a legal framework, not a declaration that individual systems are compliant.

• OMB issues federal agency AI governance and risk-management guidance

  OMB Memorandum M-24-10 directed U.S. federal agencies to establish AI governance, manage risks, publish inventories, and apply safeguards for safety-impacting and rights-impacting uses. It is binding guidance for covered federal agencies, with controls, timelines, accountability, and reporting mechanisms that differ from private-sector practice for covered uses.
