OpenAI will add a digital watermark to text and code generated in the EU

OpenAI just announced its plans to comply with part of the European Union's new AI transparency rules. The company will soon begin adding an invisible watermark to text and code generated in the EU. This follows a similar move by Anthropic earlier this year. OpenAI is using a proprietary system called textGrain that "adds an invisible statistical signal to the model's word choices." Once added, a detector can spot these signals and ascertain if there's a watermark.
