ChatGPT：再见「破折号」

Core Viewpoint - The article discusses the peculiarities of AI-generated text, particularly the frequent use of em dashes, which has become a hallmark of AI writing styles, leading to a perception that texts with excessive em dashes are likely AI-generated [6][7]. Group 1: AI Writing Characteristics - AI models, such as ChatGPT, tend to overuse em dashes in their outputs, which has led to the term "ChatGPT style" being coined to describe this phenomenon [6]. - Users have begun to avoid using em dashes in their own writing to prevent being mistaken for AI-generated content [6][18]. - OpenAI's CEO, Sam Altman, announced that users can now instruct ChatGPT to avoid using em dashes, which he referred to as a "small but happy victory" [7]. Group 2: User Experience and Feedback - Despite the update, users quickly reported that em dashes still appeared in ChatGPT's responses, indicating that the issue may not be fully resolved [9]. - Testing showed that when instructed not to use em dashes, ChatGPT complied and did not include them in its responses [10]. - The article highlights other AI tendencies, such as the frequent inclusion of English terms in parentheses and the use of quotation marks around abstract concepts, which can also detract from the overall readability of the text [15][17].
