Anthropic Rolls Out Claude Text Watermarking
Anthropic published an FAQ on adding detectable signals to Claude outputs.
TLDR
Anthropic announced via FAQ that future Claude models will embed watermarks using a secret key. The company states this meets EU AI Act rules, matches steps other developers have agreed to take, and leaves output quality and content unchanged. Andy Jones at Anthropic noted the approach draws from Google's SynthID work. Steven Sinofsky highlighted tracking risks from stored hashes. Nick Dobos replied that wording changes contradict the no-impact claim. The public posts confirm the rollout plan and these reactions.
