Overview
- Author Elizabeth Lyon filed a proposed class action in California federal court alleging Adobe used unauthorized copies of her books and others to train its SlimLM models.
- The complaint says SlimLM was pre‑trained on SlimPajama‑627B, described as a derivative of RedPajama that includes the Books3 collection of roughly 191,000 copyrighted works.
- Lyon seeks class certification, unspecified monetary damages, injunctive and declaratory relief, and an order to stop use and destroy allegedly infringing copies.
- Adobe’s own materials state SlimLM was pre‑trained on SlimPajama‑627B, an open dataset released by Cerebras in June 2023 for language model training.
- The filing adds to widening AI copyright litigation centered on Books3, following actions against major tech firms and Anthropic’s $1.5 billion settlement, as Adobe shares rose about 1.9% on the day reports surfaced.
