A new research paper and accompanying code repository reveal that fine-tuning large language models can inadvertently lead to verbatim recall of copyrighted material. The study, titled "Alignment Whack-a-Mole," demonstrates how models trained on specific texts can reproduce large portions of those texts verbatim. The researchers provide a pipeline for preprocessing books, fine-tuning models using APIs from OpenAI, Google (Gemini), and DeepSeek (Tinker), and evaluating the memorization capabilities. AI
