If you’re already tired of hearing about AI, brace yourself: it is not going away. That is why it is crucial to study AI language, from the early days of AI Dungeon (circa 2019), which gave a broad public its first taste of large language models, to the present (and beyond). In this talk, I present research on AI language using corpus- and psycholinguistic methods. Firstly, a live demonstration (or its screenshots alternative) of new publicly accessible AI-corpora, AI-Brown and AI-Koditex, will take place. Then, experiments on on AI-generated texts (including poetry), analyses of stylistic variability, and a study of AI-generated images will be presented. The goal of this talk is to offer a concise overview of recent work on large language models conducted at the Czech National Corpus. Let’s study AI before it studies us.
