Text generated by Claude models released from 2 August includes an embedded watermark designed to accompany the text, as part of Anthropic's commitments under the EU AI Act's Article 50(2) transparency Code of Practice. Within a day, an open-source "watermarks-remover" tool appeared claiming to strip such marks from Claude, Gemini, and OpenAI output.
