鱼羊 发自 凹非寺 量子位 | 公众号 QbitAI 马斯克哐哐一顿左手倒右手，让SpaceX和特斯拉给xAI输血，背后大计划现在终于浮出水面—— 宣布启动史上最大规模芯片计划Terafab。 有多大？用"宇宙级"来形容不算过分：目标是每年生产超过1太瓦算力（目前全球AI算力年产出约为20吉瓦，1太瓦=1000吉瓦），其中80%部署至太空， 20%用于地面。 用马斯克自己的话说，"这是有史以来最宏伟的芯片制造计划"、"远超人们的想象"。 SpaceX的官方公告则直接定义这个计划为"迈向银河文明的下一步"。 具体来说，Terafab项目的第一步，是在美国奥斯汀建立"先进技术工厂"，将芯片开发的所有阶段all in one： 把从设计到制造，都整合到一起，最终为机器人、人工智能和太空数据中心制造芯片。 （等于要把英伟达和台积电的活都干了…） 马斯克旗下Tesla，以及新合并的SpaceX和xAI将携手推进这一计划。 "超出人们思考水平"的芯片计划 在Terafab的发布会上，马斯克阐述了自己发布这个计划的初衷，并透露了这个超级芯片计划的技术路线。 从发布会展示的图片来看，Terafab会落地位于奥斯汀的特斯拉总部 ...
