Google 推出 Agent Compute Engine，为每个 Gemini 智能体分配硬件隔离微虚拟机
Google's Agent Compute Engine gives every Gemini agent its own hardware-isolated micro virtual machine
Google 宣布 Agent Compute Engine，为每个 AI 智能体提供独立隔离的虚拟机，该服务已支撑 Gemini，并将在未来几个月开放预览。每个智能体运行在由 Google Titanium 芯片保护的 microVM 中，空闲时自动暂停以释放机器，虚拟机间共享内存降低单机成本。Google 称其开源的 Kubernetes 运行时 Agent Substrate 可在单台服务器上容纳十倍数量的智能体，20 万智能体测试中挂起与恢复耗时低于 500 毫秒，同时新增 token 追踪、模型路由和对 Ping Identity、SailPoint 等第三方身份提供商的支持，这些管控将扩展到 Cloud Run、GKE 和托管端点。

Google announced Agent Compute Engine, a service that gives each AI agent its own isolated virtual machine. The service already powers Gemini and will open for preview in the coming months. Every agent runs inside a microVM secured by Google's Titanium chip, the company says. When an agent idles, its VM pauses automatically and frees up the machine for others. Shared memory between VMs cuts what each one costs to run. VMs are a pretty huge cost factor when providing agentic systems, so Google is going after efficiency here.
This is also behind the open-sourced Agent Substrate, a Kubernetes runtime. Google says it can fit ten times as many agents on a single server. In a test with 200,000 agents, suspend and resume took less than 500 milliseconds, according to Google. On the oversight side, Google is adding token tracking, model routing, and support for third-party identity providers like Ping Identity and SailPoint. Those controls will extend to Cloud Run, GKE, and managed endpoints.
