EU begins enforcing AI Act transparency rules for chatbots

From 2 August 2026, providers of interactive AI systems in the EU must tell users they are dealing with AI, generally at the first interaction, under Article 50 of the AI Act. An exception applies where the AI nature is obvious to a reasonably well-informed person. Generative AI systems placed on the market before that date get a labelling grace period until December 2026.

• AI disclosure must appear no later than the first interaction
• The exception applies only when the AI nature is obvious from context
• AI-generated content must be clearly marked and machine-detectable
• Existing generative AI systems have until December 2026 to comply
