OpenAI is introducing an invisible, machine-readable watermark for text generated by ChatGPT and Codex. The feature, called textGrain, is initially rolling out to users in the European Union.

The watermarking approach is designed to help identify AI-generated text without altering the visible output. OpenAI claims the method performs comparably to or better than existing techniques such as Google DeepMind's SynthID for text.

This move comes amid growing pressure to distinguish AI-generated content from human writing, particularly in education and publishing. A reliable watermark could aid detection efforts, though such systems have historically faced challenges with robustness after text modification.

Starting in the EU suggests a response to regulatory expectations around AI transparency and content provenance. Broader availability may follow depending on adoption and effectiveness.
