Google Cloud 下月向所有客户开放基于 Vera Rubin 的 A5X 实例
Google Cloud will open its Vera Rubin-based A5X instances to all customers next month.
Google Cloud 将于下月向所有客户开放基于 Vera Rubin 的 A5X 实例。伦敦广告集团 WPP 的早期测试显示，此前需要多台服务器集群运行的 AI 智能体负载，在单台 A5X 实例上即可运行。机架外部通过 ConnectX-9 网卡和 Google 的 Virgo 网络互联，可跨多个站点扩展到 960K Rubin GPU；该设计面向强化学习，更快的 CPU 到 GPU 及 GPU 到 GPU 链路可缩短每轮训练时间。

Google Cloud will open its Vera Rubin-based A5X instances to all customers next month.
In early tests by London advertising group WPP, AI agent workloads that previously needed a cluster of several servers ran on a single A5X instance.
Outside each rack, ConnectX-9 network cards and Google’s Virgo network tie racks together, letting Google Cloud scale the setup to 960K Rubin GPUs across multiple sites.
The design targets reinforcement learning, where models repeatedly generate experience, score results and retrain, so faster CPU-to-GPU and GPU-to-GPU links shorten each round.
