OpenAI adds invisible watermark to AI-generated text in EU to comply with new AI rules

OpenAI will introduce an invisible watermark in text generated by ChatGPT and Codex within the European Union to comply with the EU AI Act's transparency requirements effective from August 2. This watermark subtly alters word choices to create a detectable pattern without visible symbols, helping identify AI-generated content while preserving user privacy. The feature will roll out to eligible EU users soon and can be optionally enabled by developers worldwide via API. However, the watermark can be partially removed by editing, and OpenAI warns that absence of the watermark does not guarantee human authorship. This move follows similar steps by other AI firms like Anthropic and aligns with EU regulations on AI transparency.

OpenAI's plan to watermark ChatGPT text in the EU is notable for readers tracking technology developments. For readers following the Technology sector, here is Pluang's market snapshot as of Oct 06, 2026 03:02 WIB: out of 150 priced US tech stocks, 77 rose and 72 fell.
