OpenAI to Introduce Invisible Watermarking for ChatGPT Text in EU to Meet Regulations
AI-summarised brief · reviewed before publication
OpenAI announced that it will deploy an invisible watermark, called textGrain, on eligible ChatGPT and Codex outputs in the European Union within the next few weeks. The watermark embeds a statistical signal in word choices, allowing machine‑readable labeling without altering the visible text. Detection works best on longer passages and struggles with technical content or edited text, such as synonym replacements. The rollout aligns with the EU AI Act’s transparency requirements, while the detection tool will initially be available only to approved researchers. API users worldwide can opt in, but the feature is disabled by default.
