NVIDIA 将 Agent Substrate 捐赠给 CNCF，为大规模 Agent 扩展 Kubernetes
原标题：Agent Substrate: Advancing Kubernetes for Agents at Scale
AI 摘要
NVIDIA 将开源项目 Agent Substrate 捐赠给 CNCF Sandbox，该项目为沙箱化 AI Agent 提供零信任运行时，通过在多路复用的小型 worker Pod 池上对空闲会话做检查点与恢复，实现比标准容器高 10 倍的密度。文章指出 Kubernetes 原生模型不适合 Agent 频繁启停、长时间空闲的工作负载，并介绍了请求排队、GPU 设备插件化、容器级资源隔离等上游贡献，同时说明其与 KAI Scheduler、NVIDIA Dynamo 在 DSX AI Factory Platform 中的配合。

AI agents spend most of their time idle, waiting on a human prompt, a tool result or a model response. Kubernetes wasn’t built for that. Running one Pod per session holds memory for sessions that aren’t doing anything, and deleting Pods between turns pays a multi-second cold start every time and loses the agent’s state. RL post-training hits the same wall. Agent Substrate, now donated to the Cloud Native Computing Foundation (CNCF) Sandbox, is an open-source, security-hardened, zero-trust runtim
