From action to static descriptions: How using AI changed Jørn Lier Horst's style (jilltxt.net)

Jørn Lier Horst, a prominent Norwegian crime author, has revealed that his latest novel, *Den siste saken* (The Last Case), is significantly AI-assisted, with reports indicating that up to 74% of the text is influenced by AI. While Horst insists he remains the author and actively uses AI tools like ChatGPT for research and refining his writing, this revelation has sparked both criticism and support within the literary community. Critics argue that reliance on AI could affect the authenticity and creativity of literary works, while supporters emphasize the efficiency it brings, particularly for established authors like Horst, who continues to sell millions of copies. The use of AI in Horst's writing has led to notable stylistic changes, reflecting common features found in AI-generated text. Analyses show a shift towards more passive and descriptive language, with an increase in adjectives and nouns compared to his previous works, which were more action-driven. The novel exhibits characteristic AI clichés, such as static descriptions and sensory phrases, raising questions about the implications of AI on narrative quality and literary style. The discourse around *Den siste saken* underscores a larger conversation in the AI/ML community regarding the ethical and creative boundaries of AI-assisted writing.
