OpenAI has officially launched mandatory “textGrain” watermarking for ChatGPT in the EU, complying with strict AI Act regulations. Surprisingly, users in the US remain unaffected, leaving American outputs unmarked.

- **EU:** Mandatory, default watermarking.
- **US:** No federal mandate, no watermark.

While OpenAI claims the tech is invisible, experts warn these proprietary systems remain vulnerable to tampering and restricted detector access.
