Anthropic to Embed Invisible Text Watermarks in Claude Outputs for EU AI Act Compliance
___Patrice___ · x · 2026-08-11
Anthropic announced that new Claude models will embed invisible watermarks in all generated text globally, complying with an EU AI Act code.
The watermark is integrated directly into the text itself rather than functioning as metadata. This means it will travel with the text when copied and pasted elsewhere and may persist through some degree of editing. The feature applies to models launched on or after August 2, 2026, and Anthropic is currently working on adding it to existing models.
