OpenAI announced it's implementing watermarking for text generated by ChatGPT and Codex to comply with the EU AI Act. While editing might make these marks harder to detect, it's a significant step towards content provenance.
Take: The EU AI Act is here, and OpenAI is quick to adapt. This is basically 'tagging' AI-generated content, but true anti-forgery is a long way off. A few edits and the mark is gone; the tech and regulatory cat-and-mouse game will continue.
