OpenAI is watermarking text generated by ChatGPT and Codex for users in the European Union, using a method referred to as textGrain. The move is being discussed as a step toward making AI-generated content identifiable, in line with EU transparency expectations around artificial intelligence. Reaction so far appears focused on what this means for users and downstream AI companies.

Why now: Watermarking AI-generated text in the EU signals compliance with emerging European AI transparency rules, drawing attention from the AI community.
