THE BRIEF
1
OpenAI will begin rolling out text watermarking for eligible ChatGPT and Codex users in the European Union to comply with transparency requirements under the EU AI Act.

The technology, named textGrain, embeds an invisible statistical signal into word choices during text generation rather than adding hidden characters.

OpenAI noted that editing text significantly weakens the watermark signal, reducing detection rates from about 92% to 66% when 10% of words are replaced with synonyms.
