Where Models Converge and Humans Diverge: A Coverage Framework for Distributional Pluralism in Open-Ended Generation

The paper 'Where Models Converge and Humans Diverge: A Coverage Framework for Distributional Pluralism in Open-Ended Generation' identifies a critical gap between Large Language Model (LLM) generated content and human-authored content. While LLMs consistently reproduce fundamental elements, human writing exhibits greater stylistic irregularity and diverse plotlines, leading to 'average' LLM output compared to the broader distribution of human creativity. The paper proposes a human-grounded framework to systematically measure this distributional divergence, which has been previously observed but lacked a quantifiable metric.

The divergence between LLM and human-generated content highlights a fundamental limitation in current AI capabilities for open-ended generation, impacting the perceived originality and utility of AI-created outputs across various sectors. Addressing this gap by developing robust measurement frameworks and subsequent generation methods is crucial for enhancing the sophistication and acceptance of AI tools in creative, strategic, and communication roles.

LLMs reliably generate fundamental elements of a given domain, such as recognizable characters and settings.
