US DOJ backs fair use for AI training; DeepSeek bets on Huawei Ascend for inference

本周四条 AI 新闻：司法部站队 fair use、DeepSeek 押注昇腾、OpenClaw 转向团队、员工对 AI 情绪转冷

The US DOJ filed a statement arguing that training AI on copyrighted works is transformative fair use, separating training from output and invoking national security. The NYT pushed back; no appeals court has ruled yet. DeepSeek plans to deploy at least 160,000 Huawei Ascend 950DT chips in Inner Mongolia for inference only—training still relies on Nvidia. OpenClaw 2.0 shifts from personal assistant to team infrastructure with shared sessions, but permission boundaries are loose. Glassdoor data shows employee sentiment toward AI turned negative: positive mentions dropped from 81% in 2019 to 43% in 2026, and those mentioning AI in cons were 6x more likely to mention layoffs.
