US DOJ argues training LLMs on copyrighted text is generally fair use in OpenAI case

美国司法部就 OpenAI 版权诉讼提交意见书支持训练属于合理使用

The US DOJ filed a statement of interest in the OpenAI v. NYT copyright case, arguing that training LLMs on copyrighted text is generally fair use. It calls the training 'highly transformative' and warns that broad licensing requirements would harm US AI competitiveness on national security grounds. The filing is advisory and does not bind the court; how data was obtained and whether outputs reproduce protected passages remain separate, case-by-case questions.

Why it matters: DOJ filed a statement of interest in NYT v. OpenAI, arguing training is fair use and invoking national security. It's non-binding but signals federal posture. The post doesn't include the full brief, but the core argument is clear and directly relevant to AI builders.
