Anthropic to Embed Invisible Watermarks in Claude Outputs from August 2026 for EU AI Act
Anthropic will begin embedding invisible watermarks in text generated by its Claude model starting in August 2026. The watermarks, which are machine-readable codes, will mark the AI-generated nature of the content. This measure is designed to comply with the transparency guidelines of the European Union's Artificial Intelligence Act, which requires technology companies to label content that is generated or edited by AI in a machine-recognizable manner.
The policy has elicited mixed reactions among some Claude users, and discussions are ongoing on Reddit regarding AI content identification and attribution rights.
