The US Copyright Office's May 2025 pre-publication Part 3 report analyzes generative-AI training under existing copyright law and licensing markets; it is an expert agency policy analysis, not legislation or a final court ruling that all training is fair use or infringement.
What this does not establish
No universal legality conclusion is inferred for a particular dataset, model or output.
Counterevidence & uncertainty
Courts, licences, source acquisition, market harm, model design and future final text can change the analysis.
What would change the reading
Replace with final Part 3 and track federal cases or legislation.
