February 2025 — active for over a year
Prohibition of unacceptable AI practices (social scoring, manipulative AI, untargeted scraping of facial images, emotion recognition in work/school, risk profiling for law enforcement without narrow exceptions). AI Literacy obligation: all employees who operate AI systems or use their outputs must be trained. This also affects Microsoft 365 Copilot users broadly.
August 2025 — active since last August
Obligations for general-purpose AI models (GPAI): technical documentation, copyright compliance, transparency report. This obligation affects Microsoft as a provider of the underlying models — but not directly its customers, with one exception: anyone substantially adapting a GPAI model (fine-tuning, own data basis at large volume) may become a provider and inherit the corresponding obligations. Plus: the AI Office at the EU Commission is operational and can take initial market surveillance actions.
August 2026 — the critical threshold (three months away)
High-risk AI obligations become fully effective: risk management system, data governance, technical documentation, record-keeping (logs), transparency toward deployers, human oversight, accuracy and cybersecurity requirements, conformity assessment before being placed on the market. Plus transparency obligations for AI-generated content (watermarking, labeling of chatbots, deepfakes). Anyone building or deploying high-risk AI has extensive work here. Anyone "only" using Microsoft Copilot Standard has mostly deployer obligations (see February 2025).
August 2027 — further high-risk obligations
Extended requirements for embedded AI in regulated products (medical devices, toys, machinery, lifts, pressure equipment, etc.) — relevant for mid-market companies whose products already need CE conformity assessments. AI becomes part of the product conformity assessment here.
