Author sues Adobe for using her books to train AI
Oregon author Elizabeth Lyon is taking Adobe to court, saying the company used her nonfiction guidebooks to train its SlimLM AI model—without asking.
Her lawsuit, filed December 18, 2025, claims Adobe used her work as part of a massive dataset called SlimPajama-627B.
This set reportedly includes thousands of copyrighted books from collections like RedPajama and Books3, raising big questions about how AI companies get their training material.
Not the 1st copyright fight over AI
Lyon's case follows a string of similar lawsuits against tech giants like Apple and Salesforce for using authors' works in their AI projects without permission.
Just a few months ago, Anthropic settled for $1.5 billion after facing similar claims from writers.
Lyon's suit is aiming for class-action status—so other authors who feel their work was misused could join in too.
