Extracting Books from Production Language Models (ahmeda14960.github.io)

Researchers have successfully extracted thousands of words from copyrighted books using production language models, highlighting a significant vulnerability in the current safeguards of these advanced AI systems. By implementing a two-phase extraction process focused on "near-verbatim recall" (nv-recall)—measuring the extent of matching text between the original book and the model's output—the team demonstrated that even sophisticated guardrails failed to prevent the retrieval of proprietary content. Their work specifically referenced "Harry Potter and the Sorcerer's Stone," showcasing the practical implications of this extraction method. This research raises critical concerns for the AI/ML community, particularly in the context of intellectual property and data privacy. Despite efforts to mitigate the risk of unauthorized data extraction from large language models (LLMs), this study exposes persistent vulnerabilities that could have legal and ethical ramifications. The findings underscore the necessity for enhanced safeguards and better training data management as the AI landscape evolves, ensuring models respect copyright laws and do not inadvertently divulge sensitive information from in-copyright sources.
