Ethics & Governance

EU AI Act (Risk Tiers)

The European Union's AI regulation classifies systems into four tiers: prohibited (social scoring, manipulative or exploitative uses — banned outright), high-risk (biometrics, hiring, credit, critical infrastructure — subject to conformity assessments, documentation, and oversight), limited-risk (chatbots, deepfakes — transparency obligations), and minimal-risk (most other uses — voluntary codes). General-purpose AI models carry their own tier of obligations. Enforcement is phased through 2026 and beyond.
