The landscape of language automation has experienced notable strides in recent times, largely propelled by the advent of artificial intelligence (AI) technologies like ChatGPT. These advancements have ushered in new possibilities for comprehending and crafting text, raising an essential question: does AI empowerment solve the problems of lexicographers? Phraseology, as the study of fixed expressions and associated lexical units, imposes specific demands on linguistic processing. This article focuses on tackling these challenges by integrating the phraseological aspects of language with AI and, specifically, the capabilities of ChatGPT-4 and ChatGPT-4o to comprehend and produce phraseological units (PUs) in the monolingual contexts of French and Chinese as well as in bilingual settings involving French to Chinese and Chinese to French translation. Research shows that, for now, ChatGPT cannot replace human phraseography, especially when it comes to phraseoculture (Chen 2022), which would require “post-editing” (Jakubíček & Rundell 2023) and validation by humans. Despite this, ChatGPT remains a valuable auxiliary tool for phraseography.
