Anthropic is watermarking text generated by Claude to comply with EU law

Anthropic has revealed how it's watermarking text generated by Claude AI to comply with the European Union's new AI transparency rules. The company said its text watermarking will not have easy-to-see visuals, will not be distinguishable to the people who read it and will not be adding hidden characters to the text. Instead, Anthropic's method involves leaving a pattern in the text that can only be decoded by someone who has the key for it. The company explained that large language models pick one word at a time when generating text by choosing from a list of potential appropriate words to use. They pick words randomly, as long as they make sense for the context of what they're generating.
