# EU AI Act Article 50 Transparency Rules Activate August 2, 2026

> A concrete piece of the EU AI Act comes into force on August 2, and it will be visible to ordinary users. Article 50's transparency obligations require that chatbots and virtual assistants tell people they are interacting with a machine, and that generative AI mark its outputs so they are detectable and machine readable as synthetic. The rules go further for the trickier cases. Systems that recognize emotions or generate deepfakes must clearly disclose that use to the people affected, though law enforcement gets carved out with safeguards. There is a grace period for content already on the market before the deadline, which has until December 2 to meet the machine readable marking requirement, while newer systems must comply right away. The stakes are not trivial. Violations can draw administrative fines of up to six percent of global annual turnover, and the EU is drafting a voluntary Code of Practice to guide how labeling should work. For any company shipping AI into Europe, this is the moment abstract regulation turns into product requirements, disclosure banners, watermarks, and detectable metadata that engineering teams have to actually build.
