  AIGC tools such as ChatGPT have profoundly changed scientific research,
leading to widespread attention on its use on academic writing. Leveraging
preprints from large language models, this study examined the use of AIGC in
manuscript writing and its correlation with author profiles. We found that: (1)
since the release of ChatGPT, the likelihood of abstracts being AI-generated
has gradually increased; (2) scientists from English-speaking countries are
less likely to use AIGC tools for writing assistance, while those from
countries with linguistic differences from English are more likely to use these
tools; (3) there is weak correlation between a paper's AI-generated probability
and authors' academic performance; and (4) authors who have previously
published papers with high AI-generated probabilities are more likely to
continue using AIGC tools. We believe that this paper provides insightful
results for relevant policies and norms and in enhancing the understanding of
the relationship between humans and AI.
