Anthropic shares more details about how Claude’s new watermarks will work
Summary

Anthropic detailed how it will watermark Claude's text output using Google DeepMind's SynthID-Text approach, complying with the EU AI Act's Transparency Code. The watermark embeds detectable patterns during low-stakes word choices (e.g., 'overcast' vs. 'grey') without degrading output quality, and Anthropic plans to release a detection API. Light editing won't fully remove the watermark, but code generation is less affected due to constrained token selection, though comments may still carry watermarks.
