Anthropic's text watermarks signal new front in AI detection

Anthropic's new models will add machine-readable "watermarks" to Claude-generated text and files to comply with new European Union transparency regulations. Why it matters: Comms teams using Claude to simply clean up, translate, or format human-drafted press releases could stamp those documents with an AI signature. H

Anthropic says Claude can now embed invisible watermarks in AI-generated content.

Anthropic joins a growing list of companies letting customers know if they’re consuming AI content.

The new feature will not be visible to humans and will remain in place even after text is cut-and-pasted.

Anthropic said in a support document Tuesday that its future AI models will put an invisible watermark in all text, identifying it as AI-generated. The change comes in response to new AI transparency laws in the EU, but Anthropic says it will apply in all countries where Claude models are used. No U.S. law currently re

New models will embed an invisible, machine-readable signal in AI-generated text, part of an industry-wide push to distinguish human writing from AI output.

Anthropic announced Monday that new versions of its Claude AI models will embed an "imperceptible watermark" into the text they generate, a move that could make it harder to pass off AI slop as being created by humans.

The AI company signed the E.U. AI Act's transparency code and says new Claude models will mark content from day one of release

In compliance with EU rules, Anthropic's Claude will start watermarking AI-generated content.

Anthropic will invisibly watermark all of Claude's text and file output from 2 August to meet EU AI Act transparency rules, with the marking applied globally, whether or not the user is anywhere near Brussels.

Anthropic will extend support for watermarking AI generations for older models as well.

Anthropic will begin adding invisible watermarks to text generated by Claude as part of new EU rules designed to make AI-generated content easier to identify. But the system will also mark some text originally written by humans if it has subsequently been edited or processed by Claude, potentially complicating efforts
