Anthropic says Claude models in the EU will now add invisible watermarks to generated text and C2PA metadata to generated files, to comply with the EU AI Act (Thomas Claburn/The Register)
Anthropic will add invisible watermarks to Claude's text output and C2PA metadata to generated files for EU users, citing EU AI Act compliance.
Engineers deploying Claude in EU contexts will have their outputs tagged with traceability markers that non-EU outputs will not carry. This creates a regional divergence in how Claude outputs behave and affects how generated content can be audited or attributed downstream.
