Anthropic FAQ: Watermarking for EU AI Act, No Quality Impact
PMinervini · x · 2026-08-17
Anthropic published an FAQ addressing questions about text watermarking. Key points:
- Implementing watermarking to comply with the EU AI Act; other major model developers have signed the same Code of Practice and will also implement it.
- The method has no practical impact on Claude's output quality.
- Watermarked and un-watermarked text are indistinguishable to readers.
- Nothing is added to the text, no hidden characters.
- No extra tokens, no additional cost.
- Watermarks cannot be traced to a specific person, organization, or chat.
