AI 公司买走绝版古书，扫描完就销毁

TL;DR - Anthropic reportedly bought and destructively scanned pre-2023 books to create high-quality training data for Claude. The practice highlights growing demand for human-authored data and unresolved tensions around copyright, preservation, and model collapse.

• “Project Panama” prioritized older books considered less likely to contain AI-generated text.
• Physical books were destroyed after scanning, supporting a legal argument that the process was a one-to-one format conversion.
• A federal judge in Bartz v. Anthropic deemed this conversion fair use.
• The strategy aims to reduce model-collapse risks from repeatedly training AI systems on synthetic outputs.
