放弃火星!马斯克计划打造阿尔法月球基地
Huan Qiu Wang Zi Xun· 2026-02-13 07:46
来源:环球网 【环球网科技综合报道】2月13日,据外媒TechCrunch报道,在SpaceX与xAI完成合并、计划推进IPO之 际,特斯拉CEO埃隆·马斯克为两家公司确立了全新愿景——打造"阿尔法月球基地",以此替代搁置的 火星殖民计划,为AI与航天业务融合指明方向。这一愿景也成为xAI高管离职潮后的全新招聘筹码,马 斯克公开喊话:"若月球质量驱动器的构想吸引你,就加入xAI。" 据悉,两家公司合并后的核心协同点的是在轨AI数据中心,而马斯克将这一构想进一步延伸:要突破 地球轨道数据中心的能量局限,就必须登陆月球,建造月球城市批量生产太空计算机,并通过磁悬浮列 车将AI卫星发射至深空,甚至利用太阳能的部分能量训练和运行AI模型。 外媒报道称,这一转变源于SpaceX对火星殖民计划的务实调整。此前九年,"火星殖民"一直是SpaceX 的核心招聘和融资叙事,但该计划因缺乏商业回报、技术成本过高难以推进,如今SpaceX已将重心转 向更具可行性的月球任务,包括执行NASA价值40亿美元的登月合同、构建月球经济生态。而阿尔法月 球基地,正是马斯克为融合xAI业务打造的全新叙事,区别于行业内千篇一律的AI研发方向。 ...
Seedance2.0“真人素材参考”功能被暂停,爆火背后有两道必答题

来源:央广网 最近字节跳动推出的视频模型Seedance2.0,引起全网热议,通过几句简短的提示词就能生成电影级的 视频。比如,某特工逃避追捕时撞翻了一箱水果,橘子和苹果在空中飞舞的慢动作等,都是由AI生 成。再比如,两位根本不在一本书里的动画人物,成了真人在演戏。过去我们常开玩笑说的关公战秦 琼、黑猫警长大战孙悟空,现在只需几行提示词,就能快速呈现。 但与此同时也有人发现,该模型的模仿能力过强,不仅可以生成现实生活中的人物视频,还能高度还原 语音语态,令普通观众真假难辨。一名知名博主就在测试中发现,仅将他自己的人脸照片上传至模型, 系统就能自动生成与他本人高度相似的声音。据了解,目前平台已暂停"真人素材参考"功能。视频模型 的高速发展,给隐私保护和素材安全提出哪些新课题? Seedance2.0有多强? 这次更新的Seedance2.0有多强?与其他多模态大模型相比,有哪些优势?中关村现代信息消费应用产 业技术联盟副理事长包冉,在进行深度测试后评价:它解决了一个普遍性痛点——大模型生成内容的一 致性。 包冉表示:"迄今为止,Seedance2.0是我个人使用体验最好的一款。生成式人工智能的模型,它最大的 问 ...
