OpenAI details text watermarking approach to comply with EU AI Act provenance requirements
OpenAI has published its policy for text watermarking under EU content provenance rules, covering where watermarks apply, how detection functions, and a researcher-first access model. This signals OpenAI's formal compliance posture toward the EU AI Act's transparency requirements for AI-generated text. The phased, research-gated rollout suggests OpenAI is treating watermarking as a maturing technical standard rather than a shipping product.
