The European Union's latest transparency obligations for AI systems and deepfake content under the AI Act officially took effect on August 2. According to the new regulations, interactive AI systems such as chatbots must clearly inform users of their AI identity. Deepfake content, including images, videos, and audio generated or modified by AI, must also be clearly labeled and accompanied by machine-readable markers. This move aims to enhance transparency in online content and help the public identify AI-generated content. The European Commission stated that these regulations are designed to reduce deceptive and manipulative practices and protect consumer rights. The new rules apply to all companies providing AI services in the EU market, regardless of where their headquarters are located. Companies that violate the regulations will face fines of up to €15 million or 3% of their global annual turnover. Additionally, the EU has released a list of over 180 organizations that have signed the Code of Practice on Transparency of AI-Generated Content, which aims to promote the implementation of relevant transparency requirements.
