本轮融资完成后，OpenAI账上现金增至约1500亿美元，OpenAI称资金将主要用于扩大算力基础设施，以满足快速增长的用户需求。 01 亚马逊分期投入500亿 作为本轮融资出手最阔绰的投资人，亚马逊承诺的500亿美元投资分两阶段执行：首期150亿美元已确定投入，剩余350亿美元将在OpenAI完成 IPO或实现AGI后到位。 所以很快，奥特曼就表示，对在合适的时机上市持开放态度。 而关于AGI，按OpenAI与微软此前的合同定义，AGI指 "能够在最具经济价值的工作上超越人类的高度自主系统"。OpenAI章程中设有一项特 殊条款：一旦AGI实现，微软将失去对其技术的访问权。 但亚马逊不只是出钱，双方还签了一整套技术合作——亚马逊要用自己的芯片和云服务换OpenAI的模型和技术。 2月27日，OpenAI宣布敲定新一轮约1100亿美元融资，投前估值达7300亿美元。 这是继去年410亿美元融资后，OpenAI又一次创下纪录的募资，也是迄今为止规模最大的私营科技公司融资。 本轮融资由战略投资者主导，其中亚马逊投入500亿美元，软银和英伟达各投入300亿美元。 双方合作最核心的条款是算力采购。 OpenAI将在未 ...

听雨 发自 凹非寺量子位 | 公众号 QbitAI 一转头，OpenAI拿下了AI史上的最大一笔支票。 2月27日晚，OpenAI宣布获得新融资1100亿美元，其中300亿美元来自软银，300亿美元来自英伟达，500亿美元来自亚马逊，投前估值7300亿美元。 这也是AI领域迄今规模最大的单笔融资。 官方说法是，这笔融资将用于扩大人工智能基础设施的建设，以加快推进AI的普惠。 奥特曼还在X上描绘了与三家的具体合作方向： 英伟达：负责底层算力供给，围绕 GPU 及新一代加速器，为OpenAI提供持续、可扩展的训练与推理能力； 亚马逊：提供云基础设施与全球部署能力，支持OpenAI在多区域、多行业场景中的模型交付与商业化落地； 软银：更多承担资本与生态角色，通过长期资金支持及产业资源整合，推动OpenAI在更广泛产业体系中的扩张。 另外，作为OpenAI的老股东，微软也没落下。 双方发布联合声明表示：之前的合作关系不受影响，微软Azure仍然是OpenAI API的独家云服务提供商，并且微软拥有OpenAI模型和产品中知识产权的 独家许可和访问权限。 在同一时间，算力上游、云基础设施和长期资本三条最关键的AI资源线 ...

当地时间2月24日美股开盘前，Meta和AMD双双在官网宣布了一项为期五年的战略合作伙伴关系，Meta将部署6GW（每吉瓦容量交易金额约达数百亿美 元）的AMD GPU，作为交换，AMD将提供最多1.6亿股（约10%股权）的基于业绩的认股权证。分析人士认为，这份战略合作背后，既表明Meta在AI领域 持续扩张的强烈诉求，也成为AMD与行业龙头英伟达展开正面抗衡的重要一步。 10%股权换1000亿订单 根据协议，Meta将从2026年下半年起，在五年内采购AMD专为AI模型设计的芯片及服务器设备。AMD首席执行官苏姿丰透露，每吉瓦容量的交易金额将 达"数百亿美元"级别。这意味着，协议的总金额将超过600亿美元，有可能达到上千亿美元。 作为协议的一部分，AMD正在设计一款专门为Meta工作负载量身定制的半定制MI450 GPU。AMD预计初始出货将于2026年下半年开始，产品将采用基于 MI450架构的定制Instinct GPU以及代号为"Venice"的第六代EPYC CPU，运行ROCm软件，并基于Helios机架级平台构建。 苏姿丰表示，Meta早已深度参与AMD芯片设计，未来还将获得定制版的MI450加 ...

Meta与Advanced Micro Devices （AMD）达成了一项为期五年、总规模高达千亿美元的重磅人工智能芯片及设备采购协议。这一史无前例的合作 标志着全球科技巨头在AI基础设施领域的投资竞赛进一步升级，同时也为AMD在由英伟达主导的算力市场中赢得了关键的战略立足点。 这笔交易对AMD而言具有重大的战略意义。目前，英伟达控制着全球AI芯片市场约90%的份额，其市值高达4.66万亿美元，而AMD的市值约为 3200亿美元。 此次合作的核心在于高度定制化的硬件解决方案。AMD将为Meta提供包括定制版中央处理器（CPU）在内的多代产品，这些芯片将专门针对 Meta的低能耗和高性能需求进行优化。 据彭博报道，AMD首席执行官苏姿丰表示，公司正在提供为Meta工作负载优化的"高性能、高能效基础设施"，并指出Meta在MI450芯片的设计过 程中提供了协助。该款芯片主要针对AI的"推理"阶段（即AI模型响应用户查询的过程）进行了深度优化。华尔街日报指出，MI450采用了"芯粒 （chiplet）"架构设计，这使得其比传统的单体硅片更容易实现定制化。 "我们的野心非常大，"Meta全球基础设施负责人Santo ...

来源：投行圈子 6000亿美元的"妥协背后"：OpenAI突然砍掉一半算力预算，这场AI军备竞赛要转向了？ 这两天科技圈却被一条消息炸得人仰马翻。 OpenAI告诉投资者，到2030年，它的总算力支出"仅"为6000亿美元。 等等，几个月前奥特曼不还在嚷嚷着要砸1.4万亿美元搞基建吗？这砍掉的可不是小数目——8000亿美 元，相当于少建了3个特斯拉或者5个宁德时代。 消息一出，评论区立刻分成两派。一派高呼"AI泡沫要破了"，另一派则忙着解释"这是两个口径，不能 简单对比"。 但无论怎么解读，有一点是确定的：那个曾经喊着"给我钱，别的甭管"的OpenAI，终于开始算账了。 从1.4万亿到6000亿，这不仅仅是数字的变化。它可能意味着整个AI行业的游戏规则，正在发生一次根 本性的转向。 今天，我们就来聊聊这6000亿美元背后，到底藏着什么信号。 01 奥特曼的"妥协" 先说清楚这6000亿到底怎么回事。 去年11月，奥特曼公开画了一张大饼：未来8年投入约1.4万亿美元，用于AI基础设施建设，主要砸向数 据中心和计算资源。这个数字有多大？相当于再造一个苹果的市值。 当时整个硅谷都倒吸一口凉气。1.4万亿，这已经不是 ...
