OpenAI will start watermarking ChatGPT’s text in the EU

OpenAI is implementing invisible watermarking for text generated by ChatGPT and Codex within the European Union to comply with the EU AI Act. The watermark embeds a pattern in word choices that can be detected by specialized software, though it remains susceptible to editing.
Why it matters
This marks a significant step in regulatory compliance for AI companies, setting a precedent for transparency in AI-generated content.
OpenAI will start adding an invisible watermark to text generated by ChatGPT and Codex in the European Union to comply with the EU AI Act, the company said Monday in a blog post .
The EU AI Act’s transparency rules , which took effect on August 2, require AI companies to mark AI-generated content in a way other systems can identify.
OpenAI said the watermark will roll out over the coming weeks to eligible ChatGPT and Codex users on all plans, but only in the EU. Developers using OpenAI’s API anywhere in the world can turn it on for select models starting today; it’s off by default. OpenAI said it is not making text watermarking a global default at launch.
