Generalization to long-form creative writing
Establish whether author-specific fine-tuned AI systems (alone or in human–AI collaboration) can produce thematically coherent long-form creative works comparable to expert human writing, and derive reader preference patterns for such long-form outputs.

Last but not least our experiments were conducted at a shorter excerpt level and conclusions cannot be drawn for long form text. While we foresee a situation where human can collaborate with a finetuned AI model to create competing long form works, experimental evidence is required to make any broader claims.
