OpenAI will watermark ChatGPT text in the EU but makes it optional for API users worldwide

Intel Summary

OpenAI is implementing invisible textGrain watermarks for ChatGPT text in the European Union while allowing API customers worldwide to opt out. Reported testing indicates detection rates reach up to 95 percent, but fall to 17 percent when a quarter of the generated words are substituted.

Why It Matters

The optional watermarking policy gives enterprise API customers flexibility over their output attribution, contrasting with stricter competitor approaches like Anthropic's. However, the steep drop in detection when text is modified underscores technical limitations in relying on watermarking for synthetic text governance and authenticity verification.
