Anthropic embeds invisible watermarks in Claude outputs

Anthropic is taking a significant step towards transparency by embedding invisible watermarks in all outputs from its Claude models. This move aligns with the EU AI Act's transparency requirements, ensuring that text, code, and files generated by Claude can be traced back to the AI. While this initiative aims to enhance accountability, it has sparked debate among users who are concerned about privacy and control. The watermarks indicate that content was processed by Claude, not necessarily authored by it, and Anthropic plans to release detection tools to identify these marks.
