📄 Classifying German Language Proficiency Levels Using Large Language Models

Elias-Leander Ahlers, Witold Brunsmann, Malte Schilling (2025)

We investigate the zero-shot, few-shot and fine-tuning capabilities of Large Language Models (LLMs) to classify German texts according to the Common European Framework of Reference for Languages (CEFR). Published at the IEEE FLLM 2025 conference.
