Washington Post [no paywall] – Court filings reveal how AI companies raced to obtain more books to feed chatbots, including by buying, scanning and disposing of millions of titles. “Within about a year, according to the filings, the company had spent tens of millions of dollars to acquire and slice the spines off millions of books, before scanning their pages to feed more knowledge into the AI models behind products such as its popular chatbot, Claude. Details of Project Panama, which have not been previously reported, emerged in more than 4,000 pages of documents in a copyright lawsuit brought by book authors against Anthropic, which has been valued by investors at $183 billion. The company agreed to pay $1.5 billion to settle the case in August, but a district judge’s decision last week to unseal a slew of documents in the case more fully revealed Anthropic’s zealous pursuit of books. The new documents, along with earlier filings in other copyright cases against AI companies, show the lengths to which tech firms such as Anthropic, Meta, Google and OpenAI went to obtain colossal troves of data with which to “train” their software. The Anthropic case was part of a wave of lawsuits brought against AI companies by authors, artists, photographers and news outlets. Filings in the cases show top tech firms in a frantic, sometimes clandestine race to acquire the collected works of humanity. Books were viewed by the companies as a crucial prize, the court records show. In a January 2023 document, one Anthropic co-founder theorized that training AI models on books could teach them “how to write well” instead of mimicking “low quality internet speak.” A 2024 email inside Meta described accessing a digital trove of books as “essential” to being competitive with its AI rivals…”
