OpenAI 将默认为欧盟 ChatGPT 输出水印
OpenAI will watermark ChatGPT outputs by default—but only in the EU
OpenAI 将在欧盟地区默认为 ChatGPT 生成的文本添加水印，此举旨在遵守 8 月生效的欧盟 AI 法规要求。该欧盟专用水印技术名为 textGrain，采用专有算法在词选中嵌入人类难以察觉的特定模式，需专用检测器识别，但 OpenAI 承认其可能被具备基础技术的人规避。公司表示将向有限研究人员和机构提供检测器，并建立申请流程供其他机构加入。
OpenAI will begin automatically watermarking text generated with ChatGPT in the European Union, the company has announced. It will also offer the watermarking feature in other regions, but it will be off by default outside of the EU.
The move in Europe is driven by a need to comply with the EU AI Act, which took effect in August. It requires marking content produced by AI models in a way that another tool can detect. Unfortunately, there is still no completely effective and reliable way to do that. A few standards already exist, like SynthID and the C2PA project, but they are relatively easy to circumvent for anyone with basic know-how.
The same is likely true for OpenAI's watermark. Its method is proprietary; the company calls it textGrain, and has published a technical paper explaining how it works. But in general, it works like other LLM watermarking tools we've seen in the past: It puts patterns in the word choices that are not clear to a human reader and that don't meaningfully change the general quality of the output, but that someone with a key can use a specialized detector to find. OpenAI says it will be giving access to the detector to a limited number of researchers and organizations and providing a request-for-approval process for others to be added over time.
