AI-generated stories differ from human narratives in space and character, studies find

Two new research papers analyze the differences between AI-generated and human-authored creative writing. The first paper, focusing on narrative space, found that Large Language Models (LLMs) like GPT-4.1 and Llama 3.3 tend to overproduce "perceived space" (atmosphere and affect) compared to human writing, which favors "action space" (embodied interaction). The second paper investigates character variety in LLM-generated stories, comparing eight dimensions of character portrayal between AI and human narratives to understand how LLMs' character development differs from human authors. AI

IMPACT These studies highlight key differences in narrative construction and character development between AI and human authors, potentially guiding future LLM development for creative applications.

    CASPER in the Machine: Insights into Character Variety in LLM-Generated Stories

    arXiv:2606.22454v2 Announce Type: replace Abstract: As LLM-generated text is increasingly used, especially in fictional domains, we explore how much LLM-generated stories differ from human-written stories. In this work, we focus on characters. We borrow definitions from narratolo…
