  In the field of natural language processing, the rapid development of large
language model (LLM) has attracted more and more attention. LLMs have shown a
high level of creativity in various tasks, but the methods for assessing such
creativity are inadequate. The assessment of LLM creativity needs to consider
differences from humans, requiring multi-dimensional measurement while
balancing accuracy and efficiency. This paper aims to establish an efficient
framework for assessing the level of creativity in LLMs. By adapting the
modified Torrance Tests of Creative Thinking, the research evaluates the
creative performance of various LLMs across 7 tasks, emphasizing 4 criteria
including Fluency, Flexibility, Originality, and Elaboration. In this context,
we develop a comprehensive dataset of 700 questions for testing and an
LLM-based evaluation method. In addition, this study presents a novel analysis
of LLMs' responses to diverse prompts and role-play situations. We found that
the creativity of LLMs primarily falls short in originality, while excelling in
elaboration. Besides, the use of prompts and the role-play settings of the
model significantly influence creativity. Additionally, the experimental
results also indicate that collaboration among multiple LLMs can enhance
originality. Notably, our findings reveal a consensus between human evaluations
and LLMs regarding the personality traits that influence creativity. The
findings underscore the significant impact of LLM design on creativity and
bridges artificial intelligence and human creativity, offering insights into
LLMs' creativity and potential applications.
