Adobe Sued Over Pirated Books Used for AI Training

A proposed class-action lawsuit filed by author Elizabeth Lyon accuses Adobe of utilizing pirated books to train its SlimLM AI model. Lyon alleges that her copyrighted works were among those incorporated into the SlimPajama dataset, which Adobe used for pre-training.

The SlimPajama dataset is described in the lawsuit as a manipulated version of the RedPajama dataset, which included the Books3 collection. This collection of books has previously been a point of contention in litigation against tech companies for their AI training data.

This lawsuit against Adobe is part of a growing trend of legal challenges targeting AI companies. Similar claims have been made against Apple and Salesforce regarding their AI models, and Anthropic recently settled a similar case for $1.5 billion, highlighting ongoing legal battles over copyrighted material in AI development.
