Large Language Models (LLMs) may exhibit a tendency to use em-dashes not because they inherently prefer them, but because their training data includes a significant amount of content from WordPress websites. WordPress has automatically converted punctuation, including em-dashes, from standard hyphens since 2003. This means that text written by real people, which forms the basis of LLM training data, often contains these converted em-dashes. Therefore, the presence of em-dashes in AI-generated text is more likely a reflection of the training data's source rather than an inherent characteristic of the AI itself. AI
IMPACT Suggests that stylistic choices in AI-generated text may be artifacts of training data rather than inherent model behavior.
RANK_REASON The item discusses a nuanced observation about AI-generated text and its potential origins in training data, rather than a new release, significant event, or research finding.
