Grok API Drops Default-On Text Watermarking, Making It Opt-In

The Grok API was scheduled to apply watermarks to AI-generated text by default starting November 7. The provider has reversed that plan, and watermarking is now opt-in for developers. The change comes amid ongoing debate over how to label AI-generated text.

Why it matters: Developers building on the Grok API need to check whether their output will carry watermarks, since the default behavior they may have planned for has changed.
