Anthropic Defends AI Watermarking Ahead of EU Regulation

Anthropic defends its AI watermarking plan, stating it will watermark Claude outputs globally to comply with the EU AI Act, with watermarks first applied to new models and later to older ones; a forthcoming API will let users verify watermarks, though the technique is subtle, relies on word-choice patterns with a key, and has limitations (not easily detectable by readers, may affect longer passages, and does not change text ownership).
