Dario Amodei’s Anthropic has introduced watermarks to content crafted by their AI systems, responding to stringent European transparency regulations—a move that hasn’t been universally popular among users.
Famed for its Claude chatbot, the AI powerhouse cited the European Union AI Act’s transparency guidelines as the catalyst for this change, aimed at helping individuals differentiate between content created by humans and AI. This new law came into effect on August 2.
According to Anthropic’s support documentation, these watermarks are embedded automatically in all text, images, and files generated by their AI technology.
“Whenever a Claude-supported model produces text, an invisible watermark is seamlessly integrated into the text,” reads a statement on the company’s site. “This mark won’t be visible and won’t alter the content’s meaning, quality, or clarity.”
Additionally, Anthropic notes that these watermarks will “remain attached to the text when duplicated and pasted into other documents, potentially enduring some levels of editing.”
The watermarks will be implemented “wherever Claude is offered, worldwide,” including within the Claude Platform API, Claude Code, Claude Cowork and Claude Tag.
Anthropic acknowledged that its detection program has “limitations” and may not always identify AI-generated content, especially in cases where text has been “heavily edited, paraphrased, translated, or mixed into other writing” or the “passage is very short.”
The European Commission, the EU’s digital watchdog, has said it had “strong backing” from the tech industry in its push to clearly label AI-generated content so that users aren’t misled.
As of July 31, the EU had secured commitments from nearly 200 companies to comply with its transparency rules.
Aside from Anthropic, AI giants like Sam Altman’s OpenAI, Mark Zuckerberg’s Meta, Google and Microsoft all signed on to the pledge.
“By signing the code, providers and deployers of generative AI systems signal their intention to promote public trust in AI and to mitigate deception and misinformation,” the EU said in a press release.
The efforts by Anthropic and other companies come amid heightened concerns about the rise of so-called “AI slop” and AI-generated content being passed off as authentic.
Last month, a debut novelist’s $2 million book deal was canceled after a publisher became concerned that he had used AI to write the manuscript.
Still, Anthropic’s new policy irked some commenters, with one calling it “total bulls–t.”
Others pointed out that tech-savvy consumers may be able to find workarounds.
It’s “hard to see what Claude’s watermarking approach really solves,” one person wrote on X.
“There are already plenty of free and open-source models without watermarks, so anyone who really wants to avoid them can simply use something else.”
