With the advancement of generative artificial intelligence (AI), news outlets are increasingly incorporating large language models (LLMs) into their workflow to increase news productivity and quality. Utilizing a unique empirical setting where two major news organizations in South Korea introduced LLM-based news writing assistants, this study examines how LLM assistance affects news production and consumption. We first developed a novel framework using GPT-4o to extract information sources from news articles. We then constructed a unique dataset of 571 LLM-assisted news articles and 3,489 competing human-generated articles covering the same events. Using the DiNardo-Fortin-Lemieux reweighting method to ensure comparability between the LLM-assisted and human-generated news, our empirical analysis reveals that LLM assistance significantly increases news publication speed but reduces the diversity of information sources in news articles. Furthermore, LLM-assisted news is associated with decreased reader consumption, a trend exacerbated by reduced source diversity even with faster publication speed. Our findings contribute to the broader literature on generative AI’s role in professional content creation.
