OpenAI starts watermarking ChatGPT text in the EU

OpenAI is rolling out invisible text watermarking for ChatGPT and Codex in the European Union to comply with the EU AI Act's transparency rules. The method, called textGrain, subtly shapes word choices to leave an invisible pattern that detectors can identify. While developers globally can enable the feature via the API, it is not being made a global default. OpenAI notes that edits, translations, and short passages can weaken detection accuracy, highlighting ongoing challenges in provenance tracking.

OpenAI Introduces Text Watermarking for ChatGPT and Codex

OpenAI has announced the rollout of an invisible, machine-readable text watermarking system for both ChatGPT and Codex. Initially, this feature will be deployed exclusively for users within the European Union. The new capability relies on OpenAI's textGrain watermarking approach, which the company claims matches or exceeds other industry methods. This includes Google DeepMind's SynthID, a technology that also serves as the foundation for watermarking measures announced by Anthropic.
