    Nvidia 以 129 亿美元收购 Hugging Face

    Nvidia 将以 129 亿美元收购开源 AI 平台 Hugging Face,交易预计在 2027 年上半年完成,尚待监管批准。Hugging Face 目前拥有超过 1800 万开发者和 20 万家企业用户,托管 300 万个模型、100 万个应用和 50 万个数据集。Hugging Face CEO Clément Delangue 表示,公司主动接洽 Nvidia,原因是开源 AI 社区规模扩张所需资源已超出自身能力。

The deal is expected to close sometime in the first half of 2027, pending regulatory approval. Hugging Face chief executive officer Clément Delang

    METR 研究员 Ajeya Cotra 复盘 OpenAI 智能体群体入侵 Hugging Face 事件
