On October 21, 2026, NVIDIA and Google Cloud announced at GTC Berlin that the first A5X instances equipped with NVIDIA Vera Rubin NVL72 are already running at one customer. The two companies plan to make them generally available in November 2026 and to expand the instances to Europe. A5X combines ConnectX-9 SuperNICs, Google Cloud's Virgo network, and fourth-generation liquid cooling, targeting large-scale agentic inference and reinforcement learning workloads; Google Cloud says it plans to scale this infrastructure to as many as 960,000 Rubin GPUs. The first customer is Ineffable Intelligence, a London-based company founded by David Silver, which will use it for large-scale reinforcement learning; WPP also demonstrated a creative agent architecture based on NVIDIA Nemotron models and OpenShell on A5X.

Google Cloud to open Vera Rubin-based A5X instances to all customers next month
Google Cloud will open Vera Rubin-based A5X instances to all customers next month. Early tests by London advertising group WPP show that AI agent workloads that previously required multiple server clusters can run on a single A5X instance. Externally, racks are interconnected via ConnectX-9 network cards and Google's Virgo network, scaling across multiple sites to 960K Rubin GPUs; the design targets reinforcement learning, where faster CPU-to-GPU and GPU-to-GPU links can shorten each training round.
