Anthropic's Controversial Book Scanning for AI Training

Anthropic has been revealed to have destroyed millions of print books to train its AI model, Claude, as part of a legally sanctioned fair use operation.

Anthropic has been revealed to have destroyed millions of print books to train its AI model, Claude. This operation was part of a legally sanctioned fair use process, as detailed in recent court documents. The company hired Tom Turvey, formerly of Google Books, to lead the acquisition and digitization of these books, aiming to replicate Google's successful book digitization strategy.

The process involved purchasing used books in bulk, removing their bindings, and scanning the pages into digital formats, after which the physical copies were discarded. This method was deemed transformative by Judge William Alsup, who ruled that the operation qualified as fair use because Anthropic legally purchased the books and did not distribute the digital copies.

The decision highlights the AI industry's demand for high-quality text data, which is crucial for training large language models like Claude. These models rely on vast amounts of well-edited text to improve their capabilities, making the acquisition of such data a competitive necessity. Despite the legality of the process, Anthropic's earlier use of pirated materials had initially complicated its legal standing.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
