EU AI Act watermarking rules take effect, paper questions text verification
Article 50 of the EU AI Act took effect on August 2, 2026, requiring generative AI providers to mark their outputs so they can be detected as machine-generated. A new research paper analyzes the state of AI text watermarking under these rules, coming shortly after Anthropic disclosed that Claude outputs carry watermarks. The authors highlight that current text watermarking techniques still lack reliable verification, creating tension with the new compliance requirements.
