Anthropic released an FAQ regarding text watermarking for Claude. Key points: watermarking is implemented to comply with the EU AI Act, with other major developers following suit; the method has no practical impact on output quality or content; readers cannot distinguish watermarked text; nothing is added to the text or hidden characters; it requires no extra tokens and incurs no extra cost; and watermarks cannot be traced to specific individuals, organizations, or chats.
