OpenAI to Watermark ChatGPT and Codex Text in EU
OpenAI will add invisible watermarks to ChatGPT and Codex text for European users, aiming to comply with the EU AI Act.
## OpenAI’s New Compliance Measure OpenAI disclosed that it will begin watermarking the text generated by its ChatGPT and Codex models for users in the European Union. The move is intended to satisfy the requirements set out in the EU’s AI Act, which calls for traceability of AI‑generated content.
## How the Watermark Works The watermark is an invisible marker embedded directly into the model’s output. While the mark is not visible to end‑users, it can be detected by tools designed to verify the origin of the text. OpenAI notes that post‑generation editing can make these invisible marks harder to detect, potentially affecting verification efforts.
## Implications for Users and Developers For developers integrating ChatGPT or Codex into EU‑focused applications, the watermark adds a layer of accountability but may also require additional checks if content is heavily edited. The company’s statement underscores its commitment to aligning with emerging AI regulations while maintaining the utility of its models.
