### [Our approach to EU text provenance rules](https://mediarelease.co/us/mr01206-our-approach-to-eu-text-provenance-rules-05102026.html)

Issued by: OpenAI · Original source: https://openai.com/index/eu-text-provenance/

OpenAI has set out a phased approach to text watermarking in response to the EU AI Act. API customers globally can now opt in to watermarking for select models, and invisible watermarks will be added to eligible ChatGPT and Codex text output in the European Union over the coming weeks. Access to its textGrain detector will initially be limited to approved researchers and expert organizations, as detection weakens on short or edited text.
