OpenAI 正式在 ChatGPT 与 Codex 中引入文本水印技术

在欧盟地区推出文本水印。 在接下来的几周内，我们将仅面向欧盟地区所有订阅方案的合规 ChatGPT 与 Codex 用户引入文本水印功能。我们在上线初期并未将其设为全球默认配置，这种按区域逐步推进的方式能让我们从真实世界的使用和反馈中不断吸取经验。

为 API 客户提供水印选择加入功能。 即日起，全球 API 客户可以为选定的模型自主选择开启带水印的文本输出。这使得客户能够根据自身的透明度合规义务以及为用户提供的具体体验，决定如何应用水印技术。我们同时在与各大云服务合作伙伴协作，计划在未来几周内为通过其云服务调用的 OpenAI 模型输出提供水印支持。

向研究人员与专家机构开放检测工具访问权限。 获得批准的研究人员和专业机构从今天起可以申请使用。根据《实践守则》（Code of Practice），访问权限初期将采取个案逐一审批的方式授予，以支持对文本来源追溯技术的评估与改进。该工具仅会报告是否检测到 OpenAI 的水印，不会识别具体用户，也不会泄露其提示词或对话内容。考虑到存在水印漏检和误报的风险，我们在初期不会向公众全面开放该检测工具。

Rolling out text watermarking in the EU. Over the coming weeks, we will introduce text watermarking to eligible ChatGPT and Codex users across all plans in the EU only. We are not making text watermarking a global default at launch. This regional approach gives us room to learn from real-world use and feedback.

Enabling opt-in watermarking for API customers. Starting today, API customers around the world will be able to opt in to watermarked text outputs for select models. This lets customers decide how watermarking fits their transparency obligations and the experiences they provide to users. We are also working with cloud partners to make watermarking available for OpenAI model outputs accessed through their services in the coming weeks.

Providing detector access to researchers and expert organizations. Approved researchers and expert organizations can apply starting today. In accordance with the Code of Practice, access will be initially granted on a case-by-case basis to support evaluation and improvement of text provenance. The tool will report whether it detects an OpenAI watermark, without identifying the user or revealing their prompts or conversations. Given the risk of missed watermarks and false positives, we are not making it publicly available at launch.
