测出问题怎么办
· 更换网络环境后，在新对话里重测一次
· 保存带日期的截图，隔天再测对比
· 在 ChatGPT「设置 → 帮助」里反馈
· 两次复测都正常，就不用再测了
证明不了什么
本工具只对指纹库里的 16 个模型做归因。如果实际模型不在库里，得到任何结果都有可能。这里显示的是 API 模型名，与 ChatGPT 界面上的名称不一一对应，不能据此确认 ChatGPT 实际使用的模型。
原理与来源
ModelTrace 用模型生成长整数序列时的数字偏好做指纹，把回答和指纹库对比，看它更像哪个候选模型；1 题就能出结果，多测几题更稳；网页版系统提示词可能影响数字偏好，结果仅供参考，不能据此确认 ChatGPT 实际用的模型。
