arXiv abstracts show LLM-style words peaked after ChatGPT, then started fading

A chart tracking LLM-associated words in arXiv abstracts from 2021 to 2026 shows a clear post-ChatGPT shift in academic writing.
The terms “delve,” “pivotal,” “intricate,” “realm,” and especially “em dash” are tracked over time. According to the plot, some LLM-ish phrasing rose sharply after ChatGPT’s launch and later declined, while em dash usage keeps climbing. The post suggests researchers may now be consciously avoiding obvious AI-sounding words.
