Elias in the Lighthouse, Again? Diagnosing Low Diversity in LLM Stories

A recent study analyzed 20,000 stories generated by four current language models using five prompts, revealing a concerning lack of diversity in the narratives. The findings indicate that 11 words, including names like Elias and Mara, and settings such as lighthouses, appeared in 88.3% of the stories, suggesting a reliance on limited datasets and preference data that may have influenced model training.
