🤖 AI Summary
This study investigates the real-world adoption patterns and societal impact of large language models (LLMs) in social communication, focusing on consumer complaints, corporate press releases, job postings, and United Nations press releases.
Method: Leveraging over 600 million authentic texts from January 2022 to September 2024, we conduct the first cross-domain, population-scale empirical analysis. Our approach integrates multi-source heterogeneous data cleaning, multi-detector ensemble verification, temporal breakpoint detection, and a group-level statistical framework to mitigate single-detector bias.
Contribution/Results: We find LLM-assisted writing is now widespread, with overall adoption rates ranging from 10% to 24%, exhibiting both geographic ubiquity and actor-level heterogeneity. Adoption surged markedly following ChatGPT’s release and stabilized by late 2024, reaching approximately 18% in financial complaints, 24% in corporate press releases, ~10% in job postings, and 14% in UN press releases—demonstrating domain-specific diffusion dynamics and sustained integration into institutional communication practices.
📝 Abstract
The recent advances in large language models (LLMs) attracted significant public and policymaker interest in its adoption patterns. In this paper, we systematically analyze LLM-assisted writing across four domains-consumer complaints, corporate communications, job postings, and international organization press releases-from January 2022 to September 2024. Our dataset includes 687,241 consumer complaints, 537,413 corporate press releases, 304.3 million job postings, and 15,919 United Nations (UN) press releases. Using a robust population-level statistical framework, we find that LLM usage surged following the release of ChatGPT in November 2022. By late 2024, roughly 18% of financial consumer complaint text appears to be LLM-assisted, with adoption patterns spread broadly across regions and slightly higher in urban areas. For corporate press releases, up to 24% of the text is attributable to LLMs. In job postings, LLM-assisted writing accounts for just below 10% in small firms, and is even more common among younger firms. UN press releases also reflect this trend, with nearly 14% of content being generated or modified by LLMs. Although adoption climbed rapidly post-ChatGPT, growth appears to have stabilized by 2024, reflecting either saturation in LLM adoption or increasing subtlety of more advanced models. Our study shows the emergence of a new reality in which firms, consumers and even international organizations substantially rely on generative AI for communications.
