According to a post on X by @adolandev, xAI's documentation says Grok 4.x API output, including structured outputs and tool-call arguments, will carry an invisible watermark that shapes word choice. The stated reason is compliance with the EU AI Act, and the change is set to apply from November 7. Team admins can opt out per model in the Console by confirming a legal exception applies, and an x-watermark header shows whether a response was marked.

Why it matters
Developers and businesses building on xAI's API would receive marked output by default unless an admin opts out with a confirmed legal exception. Anyone publishing generated text should check the x-watermark header and whether their team qualifies for an opt-out. Watch for xAI's full documentation to confirm the scope and how the watermark affects word choice.
