被视为"欧洲版OpenAI"的法国人工智能初创公司Mistral正通过一项重大的跨境投资，加速构建欧洲本土 的AI计算能力，此举不仅标志着这家独角兽企业战略重心的扩展，也凸显了欧洲在地缘政治紧张局势 下寻求科技主权的迫切需求。 据CNBC报道，Mistral周三宣布将投入12亿欧元（约合14.3亿美元）在瑞典建设数字基础设施，重点包 括人工智能数据中心、先进计算能力以及本地化的AI功能开发。这是Mistral在其本土市场法国以外进行 的首个AI基础设施投资，预计新设施将于2027年投入运营，届时将支持该公司下一代AI模型的开发与 运行。 作为投资计划的一部分，Mistral将与瑞典公司EcoDataCenter合作部署"大规模"AI计算能力。北欧地区凭 借较低的能源成本和利于散热的寒冷气候，正成为欧洲计算设施的首选地。此前，OpenAI也于去年7月 宣布作为其"Stargate"计划的一部分，将在挪威启动AI数据中心项目。 Mistral首席执行官Arthur Mensch表示，此项投资是建立欧洲独立AI能力的具体步骤，旨在通过提供数 据本地处理和存储的全垂直服务，加强欧洲的战略自主权和竞争力。这也为服务于工 ...

大摩认为，OpenAI与甲骨文云的五年收入复合增速预测（108%与75%）在美股75年历史中从未出现。历史来看，90年代末到00年代初的电信投资潮， 最后留下的是产能过剩和破产案例。AI数据中心属于超支率极高的"大工程"，且巨额融资与股权激励正稀释股东价值。 ChatGPT在2022年底把生成式AI推到大众视野后，投资端的变化更快：企业在AI硬件、数据中心上的投入力度，已经接近美国历史上几次最大的投资 浪潮。市场随之抛出一堆漂亮的收入曲线，但问题也变得尖锐—— 这些预测到底有多大概率能实现，值不值得为此付出资本和时间成本？ 摩根士丹利投资管理旗下Counterpoint Global的Michael J. Mauboussin在10日的报告中直截了当地给出方法论：评估这类前瞻判断，应该"starting with an initial belief and updating that belief as new results appear"，也就是"贝叶斯公式"："新结论 = 初始判断（先验概率） × 新证据带来的调整系 数（似然比）"。 | New and improved belief | !! | R ...

先给大家看一段视频，你们觉得拍这么一段得花多少钱多长时间？ 如果我说，这根本不是实拍，而是AI在几分钟内"一键生成"的，你敢信吗？ 春节前，当大家还在忙着抢红包的时候，字节跳动毫无征兆地扔出了一颗"王炸"——新一代视 频生成模型Seedance 2.0。 AI生成视频不是什么新鲜事，但过去可能得花不菲的价钱，反复生成几十次，才能赌到一个勉 强能用的片段。但Seedance 2.0不一样，它号称"一条过"， 一次生成的视频可用率据说能达到 惊人的90%。 光能看还不够，它还能把你的想法，直接变成"导演级"的叙事，知道什么时候该特写，什么时 候该拉远，还能让不同镜头里的主角保持一致。影视飓风的Tim在体验后都抑制不住兴奋地表 示，模型在摄像机运动、分镜连续性以及音画匹配上都非常出色。 这意味着什么？这意味着，导演、摄影师、剪辑师、配乐师……这个传统影视工业链条，正在 被一个模型"打包压缩"。有专业摄影人士分析，如果 人工制作一段十几秒打斗视频，涉及CG 制作、动作捕捉、3D建模、后期合成等，需要跨部门协作数周甚至一两个月。而现在，这个 过程被压缩到了几分钟。 另一方面，我们也不能忽视背后的风险。Tim发布的实测视 ...
