Breaking news from OpenAI, and this one isn't about a flashy new model. It's about a hidden signature getting stamped on everything ChatGPT writes.
OpenAI just announced it will start adding an invisible watermark to text generated by ChatGPT and Codex, starting with users in the European Union.
Why now? Because the EU AI Act's transparency rules kicked in back on August 2, requiring AI companies to mark AI-generated content in ways other systems can detect.
Think of it like the hidden thread woven into paper currency. You can't see it with your eyes, but a scanner knows exactly what it's looking at.
The rollout starts with eligible ChatGPT and Codex users across all plans, EU-only for now. Developers using OpenAI's API anywhere in the world can opt in for select models today, though it stays off by default.
If Europe is first, the real question is: how long before this becomes the global default?
