OpenAI will watermark ChatGPT text in the EU but makes it optional for API users worldwide
OpenAI will add invisible text watermarks to ChatGPT in the EU, while allowing API customers worldwide to opt out. Tests show detection rates up to 95%, dropping to 17% when a quarter of words are replaced.

OpenAI is introducing invisible watermarks for text generated by ChatGPT in the European Union, responding to regional regulatory expectations around AI content provenance.
Unlike Anthropic, which has taken a different stance on watermarking, OpenAI will let API customers globally choose whether to apply the marker. This opt-out approach balances transparency goals with concerns from developers who worry watermarked output could be filtered or stigmatized.
Reported detection accuracy reaches 95% under controlled conditions, but degrades to 17% when roughly 25% of the generated words are altered. That fragility raises questions about how effective the watermark will be against deliberate evasion.
The move signals growing pressure on AI labs to make synthetic text identifiable, especially in jurisdictions pushing for stricter AI governance. Whether voluntary, opt-in watermarking becomes an industry norm or remains a compliance patch will depend on adoption and regulatory enforcement.
