A5X instances combine NVIDIA's Vera Rubin NVL72 system, ConnectX-9 SuperNICs, Google Cloud's Virgo network and fourth-generation liquid cooling. They target agentic inference and large-scale reinforcement learning workloads, and join Google's AI Hypercomputer as one integrated system of compute, networking and storage.
The first customer with access is London-based Ineffable Intelligence, founded by AlphaGo creator David Silver, which uses the platform for large-scale reinforcement learning of systems that learn continuously from experience. Advertising group WPP demonstrated a creative-agent architecture on A5X using Nemotron models and OpenShell; according to NVIDIA, workloads that previously needed a multi-node cluster ran on a single instance.
Separately, Google Cloud will be among the first cloud providers to offer NVIDIA Confidential Computing at rack scale on bare-metal instances such as A4X Max, based on GB300 NVL72, to protect proprietary models and sensitive data even when they run on infrastructure the organization does not own.
