=== The Opt-Out Litigation ===

The case (''Carreyrou et al. v. Anthropic PBC et al.'', Case No. 3:25-cv-10897) was filed in the U.S. District Court for the Northern District of California, San Jose Division, by authors who chose not to participate in the '''Bartz v. Anthropic''' $1.5 billion class action settlement covering approximately 500,000 titles. The opt-out deadline was January 29, 2026, and these plaintiffs are pursuing individual statutory damages of up to $150,000 per work rather than accepting the class settlement terms.

=== Named Defendants ===

* '''Anthropic PBC''' — Training Claude on copyrighted books
* '''Google''' — Use of copyrighted works in AI training
* '''Meta Platforms''' — Use of copyrighted works in LLaMA training
* '''xAI''' — Use of copyrighted works in Grok training
* '''Perplexity AI''' — Use of copyrighted works in AI search models

Claims against OpenAI were initially included but have been severed and transferred to multidistrict litigation (MDL), separate from the remaining omnibus case.
