The EU AI Act is already partially in force
Prohibited AI practices have been enforceable since February 2, 2025. General-purpose AI model obligations - which cover the foundation models underlying Microsoft 365 Copilot - became applicable August 2, 2025. August 2, 2026 is the full enforcement date for high-risk AI systems. This is a staged regulation that is already active for part of the stack most organizations are deploying.
