OpenAI Implements EU-Only Invisible Watermarking for ChatGPT Texts
OpenAI announced it will introduce an invisible watermark to texts generated by ChatGPT and Codex within the European Union to meet the requirements of the EU AI Act. The watermark, which subtly influences word choices, will be gradually rolled out to eligible users in the EU over the coming weeks, while API users globally can enable it for select models starting immediately. The technique is designed to be undetectable to readers but identifiable by specialized detectors, and it remains in the text even after copying or pasting.
