OpenAI 说明文本水印机制的能力与边界
OpenAI 表示希望在可能时给用户选择，并说明文本水印能做什么、不能做什么。文本水印通过在生成文本中嵌入不可见的统计信号，让检测器判断文本是否可能由 OpenAI 模型生成，不会添加可见标记或特殊字符，也不涉及文本原作者、归属、个人、组织、账号、对话或提示词。OpenAI 称测试中水印未影响模型能力、速度或回答的可读性。
When possible, we want to give people a choice—and be clear about what watermarking can and can’t do.
A text watermark helps answer one question: “Was this likely generated by an OpenAI model?”
It works by embedding an invisible statistical signal in text as it’s generated. A detector can look for this signal, and it doesn’t add visible marks or special characters. It doesn’t say who originally wrote the text or who owns it. It doesn’t identify a person, organization, account, conversation, or prompt.
In our testing, watermarking hasn’t affected how capable or fast our models are, or how their responses read.
