美东时间12月2日周二，亚马逊云计算部门AWS在年度云计算盛会re:Invent上推出新一代人工智能（AI）训练芯片Trainium 3，预告了下一代产品 Trainium 4的开发计划，加大力度挑战英伟达和谷歌在AI芯片市场的主导地位，同时推出Nova 2系列模型和全新AI服务，试图在激烈的AI竞争中抢 占更多市场份额。 AWS宣布，Trainium 3芯片已于近期部署至少数几个数据中心，并从本周二当天起向客户开放使用。AWS的副总裁Dave Brown表示："进入明年 初，我们将开始非常非常快速地扩大规模。" 这款芯片的推出速度超出业界常规。亚马逊在部署前一代加速器约一年后便发布了Trainium 3，与英伟达承诺的每年发布新芯片的快节奏相当。 亚马逊希望吸引寻求性价比的公司。公司宣称，Trainium芯片能以比英伟达市场领先的图形处理单元（GPU）更低廉和高效的方式，为AI模型背后 的密集计算提供动力。Brown表示："我们对Trainium实现正确的价格性能比的能力感到非常满意。" 亚马逊周二不仅发布了四款新模型，还推出了业内首创的"开放式训练"服务Nova Forge，并发布了专注于浏览器任务自动化 ...

推出自研芯片是亚马逊在AI领域脱颖而出战略的关键一环。AWS是云计算和数据存储服务的最大供应 商，但在AI工具的主流开发者群体中，该公司却难以复制这种主导地位。部分企业更倾向于选择与 ChatGPT开发商OpenAI联系紧密的微软(MSFT.US)合作，或是选用谷歌(GOOGL.US)的相关服务。 此举将加剧AI芯片市场的竞争态势。当前英伟达在该市场占据主导地位，其在用于训练ChatGPT等大语 言模型的芯片市场上估计拥有80%至90%的份额。 就在上周，有消息称Meta(META.US)将在数据中心采用谷歌AI芯片，引发行业震动。这预示着目前全 球市值最高企业、AI投资热潮风向标英伟达将迎来新的竞争。此前一个月，谷歌最新发布的AI模型正 是使用其自研芯片而非英伟达硬件完成训练。 亚马逊试图以高性价比吸引企业客户。该公司称，与英伟达占据市场主导地位的GPU相比，Trainium系 列芯片在支撑AI模型密集型计算任务时，具备更高的成本效益和运算效率。 智通财经APP获悉，亚马逊(AMZN.US)旗下云计算部门AWS正加速将其最新一代人工智能(AI)芯片推向 市场，力图在硬件领域与英伟达(NVDA.US)和谷歌( ...

每经编辑｜陈柯名 据新华社，美国总统特朗普2日在白宫举行的内阁会议上说，他很可能在2026年初公布下任美国联邦储备委员会主席提名人选，以接替将于2026年5月结束 任期的现任主席鲍威尔。特朗普当天还确认，美国财政部长贝森特无意担任美联储主席的职务。此前，特朗普称已就新任美联储主席提名人选做出决定。 彭博社援引知情人士说法报道，在特朗普及其顾问和盟友眼中，白宫国家经济委员会主任凯文·哈西特是下任美联储主席的头号候选人。 据报道，哈西特因与特朗普的密切关系而占据优势，这是其他竞争者无法比拟的。他曾在2017年至2019年担任白宫经济顾问委员会主席，2020年新冠疫情 爆发后短暂回归担任高级顾问，今年1月特朗普重返白宫后出任国家经济委员会主任。 除忠诚度外，哈西特的优势还在于他是一位发表过论文的经济学博士，曾在美联储担任经济学家。他拥有扎实的保守派资历，2017年参议院以两党多数票 确认其担任经济顾问委员会主席。 在特朗普第一任期内，哈西特曾坚定捍卫央行独立性的重要性，但今年他与特朗普一道尖锐批评美联储和鲍威尔。他在夏季和上个月指责美联储因未更积 极降息而存在党派偏见，这一指控几乎遭到所有央行政策制定者的反对。 大 ...
