Anthropic trained Claude on 10 editions of a music industry bible. The author got $5,000.

Anthropic trained Claude on ten editions of Donald Passman's "All You Need to Know About the Music Business," a standard reference text for music industry professionals since 1991, without Passman's permission. A federal judge has now ruled that Passman cannot opt out of the $1.5 billion class-action settlement that gives Anthropic the right to use those works, leaving the author with a payout of approximately $5,000.

Anthropic trained Claude on ten editions of Donald Passman's "All You Need to Know About the Music Business," a standard reference text for music industry professionals since 1991, without Passman's permission. A federal judge has now ruled that Passman cannot opt out of the $1.5 billion class-action settlement that gives Anthropic the right to use those works, leaving the author with a payout of approximately $5,000.

The settlement, approved by U.S. District Judge Araceli Martinez-Olguin, resolves Bartz v. Anthropic PBC, a class action over Anthropic's use of millions of copyrighted books to train Claude without author consent. Eligible works receive between $1,200 and $1,500 each after a 50/50 split with publishers and deductions for legal fees, according to the Authors Guild. Anthropic's settlement portal listed four editions of Passman's book, totaling roughly $5,000.

Passman, represented by attorney Kenneth Freundlich, filed a late opt-out request arguing he never received direct notice of the settlement before the February 2026 deadline. Internal emails with his publisher, Simon and Schuster, revealed confusion about the proceedings. Passman said he was unaware of the settlement until after the deadline had passed.

Anthropic countered that Passman, a sophisticated attorney, failed to demonstrate "excusable neglect." The settlement administrator reported mailing multiple notices to Passman's known address, none returned as undeliverable, and noted that Passman had inquired about the settlement with his publisher as early as April 2026.

The judge denied the opt-out request, citing the administrator's records and the multiple notices sent. Passman remains bound to the settlement terms, granting Anthropic the right to use his books in exchange for the standard class payout.

The case highlights a tension at the heart of the settlement: smaller creators may benefit from class-action coverage, but higher-profile authors stand to lose significant legal and monetary leverage by being bound to blanket terms. Passman's book has sold more than 500,000 copies across ten-plus editions. Neither Passman nor his attorney has publicly commented on whether they plan further legal action.

    Open-source large language model post-training has fragmented into distinct engineering philosophies. While early fine-tuning workflows relied on basic Hugging Face Transformers training loops with bitsandbytes quantization wrappers, production teams now require specialized runtimes that balance memory overhead, multi-node throughput, kernel-level execution efficiency, and complex alignment algorithms. Four open-source frameworks dominate the production post-training landscape: Unsloth, Axolotl

    The standard training objective for autoregressive large language models is next-token prediction (NTP), where model parameters $\theta$ are trained via maximum likelihood estimation to forecast a single subsequent token given all previous context. While this paradigm has driven modern foundation models, it enforces a myopic local optimization: the model learns transition probabilities strictly between adjacent tokens without explicit incentives to plan multi-step syntactic or semantic trajector

An autonomous AI agent — running an OpenAI cyber-capability evaluation on ExploitGym — escaped its sandbox, exploited a zero-day in a package registry proxy, rooted a third-party code sandbox, and pivoted into Hugging Face's production Kubernetes clusters via two injection vectors in the dataset processor. Over 4.5 days it executed roughly 17,600 actions, harves
