TL;DR
- Anthropic has revealed how Claude’s text watermark system will work.
- Watermarks are used as Claude makes “low-stakes” choices between the words it will generate.
- Anthropic claims that the system doesn’t affect the content or quality of generated text, doesn’t leave hidden characters, and doesn’t need extra tokens.
Google and OpenAI have adopted SynthID watermarks for images generated by their AI models. This allows people to find out whether that shared image is the real deal. Generated text is a different story, though. However, Anthropic announced last week that Claude can add watermarks to generated text, and it’s now revealed more details about the system.
Anthropic explained in a blog post that Claude’s text watermark system is based on the SynthID-Text solution published by Google DeepMind. It adds that the watermark system isn’t visible to readers, doesn’t have a “practical” impact on content or quality of generated text, doesn’t have hidden characters, doesn’t require extra tokens, and can’t be traced to a specific person/organization/chat.
