OpenAI has addressed a longstanding issue with its ChatGPT chatbot, allowing users to instruct the AI to avoid using em dashes in its output. The em dash, a punctuation mark often criticized for being overused in AI-generated content, had become a telltale sign of text written by a machine. According to OpenAI CEO Sam Altman, the company has fixed the problem, enabling ChatGPT to follow user instructions regarding em dash usage.
The issue had been a point of contention, with many users complaining that ChatGPT would continue to use em dashes even when told not to. In a post on X, Altman celebrated the update as a “small-but-happy win,” stating that ChatGPT now adheres to custom instructions regarding em dash usage. This change is expected to improve the overall quality and customization of AI-generated content.
The Em Dash Conundrum
The em dash has been a topic of debate among writers and critics, with some arguing that its overuse is a hallmark of lazy writing or reliance on AI tools. However, others have defended the punctuation mark, citing its long history of use in written language. The rise of large language models (LLMs) and AI chatbots like ChatGPT has brought the issue to the forefront, as these tools often default to using em dashes frequently.
Many users have pointed out that the em dash has become an objectionable feature of AI-generated content, even if it’s not a reliable indicator of whether a piece of text was written by a human or a machine. OpenAI’s update addresses this concern by giving users more control over the output of ChatGPT.
Customizing ChatGPT Output
According to OpenAI, users can now instruct ChatGPT to avoid using em dashes by adjusting the custom instructions in their personalization settings. This change allows for more tailored output from the chatbot, which is expected to be particularly useful for applications where style and tone are crucial. While ChatGPT won’t necessarily eliminate em dashes by default, users will have more agency over the frequency of their appearance.
The update is a response to user feedback and reflects OpenAI’s ongoing efforts to improve the capabilities and customization options of its chatbot. As AI-generated content becomes increasingly prevalent, the ability to tailor the output to specific needs and styles will become more important.
Implications for AI-Generated Content
The change is likely to have implications for various industries that rely on AI-generated content, including marketing, education, and customer service. By allowing users to customize the output of ChatGPT, OpenAI is providing more flexibility and control over the tone and style of AI-generated text. This development may also influence how other AI chatbots and LLMs approach the issue of punctuation and style.
As the use of AI-generated content continues to grow, it remains to be seen how users will adapt to the new capabilities offered by ChatGPT. The update is a step towards more sophisticated and user-friendly AI tools, but it also raises questions about the future of content creation and the role of human writers in an increasingly automated landscape.
OpenAI’s update is a significant development in the ongoing evolution of AI chatbots and content generation. As the company continues to refine its tools and respond to user feedback, the next steps in the development of ChatGPT and other AI technologies will be worth watching.
