DeepSeek Clarifies Use of Temporary Tags in Deep Thinking Mode

DeepSeek responded to questions regarding the discovery of user nicknames in its deep thinking mode. The company clarified that the practice refers to "contextual tags" temporarily generated during reasoning to organize responses—such as identifying "user who constantly questions" or "intentional test"—and does not constitute memorization of nicknames. These markers are not stored, do not persist in user memory, and lack any emotional or disrespectful connotation. The practice is solely intended to structure the focus of responses during the inference process.
