公众号记得加星标⭐️,第一时间看推送不会错过。 当Meta Platforms与英伟达(Nvidia)达成大规模 AI 系统交易时,通常意味着该公司此前的某些开 放硬件计划已无法满足紧迫的算力需求。这与项目延期不完全是一回事,但效果是一样的。提醒一 下,这类情况我们掌握的数据并不多,而如今这家社交网络巨头、AI 模型厂商与 AI 硬件巨头英伟 达之间宣布的巨额合作,已是第三起。 这笔交易远比 Meta 上一次与英伟达的合作规模更大,对英伟达而言价值至少数百亿美元,再加上原 始设计制造商将英伟达芯片集成到 Meta 系统中所能获得的额外收益。 在前两起案例中(几乎可以确定第三起新案例也是如此),一旦 AI 算力需求足够紧迫,Meta 便愿 意放弃自家开放计算项目(OCP)的设计方案。 在超大规模云厂商与大模型厂商中,Meta 的定位略有不同:它不只是为搜索加入 AI 能力,或是打 造能与 OpenAI、Anthropic 等抗衡的通用大模型,同时还高举开源大旗(至少目前是这样)。该公 司还运营着庞大的高性能集群集群,作为旗下各类服务的推荐引擎。这些系统需要CPU 与加速器紧 密耦合,让加速器能直接访问 CPU ...
