A new study published on arXiv explores the effectiveness of different methods for adapting large language models (LLMs) to specialized domains and languages, using French medical question-answering as a case study. The research compares continual pretraining (CPT) and supervised fine-tuning (SFT), both individually and in combination, across various model families and sizes. Findings indicate that for multiple-choice questions, CPT+SFT often yields the best results, though SFT alone is a cost-effective alternative. For open-ended questions, CPT improves overlap-based metrics, while SFT can degrade quality, with instruction tuning and CPT+SFT being preferred by LLM-based evaluations. The study also demonstrates effective cross-lingual transfer from French to English benchmarks, offering practical guidance for adaptation strategy selection under computational constraints. AI
