核心信息
腾讯AI开源了Cube Sandbox，这是一个轻量、安全且高并发的AI智能体沙箱运行时，冷启动低于60毫秒，并完全兼容E2B SDK。
要点
- 基于RustVMM和KVM构建，兼顾硬件级隔离与高性能。
- 冷启动低于60毫秒（快2.5–50倍），单实例内存占用低于5MB。
- 单节点可支撑数千并发沙箱，替换端点即可无缝迁移，零代码修改。

原始推文
🥳We just open-sourced Cube Sandbox! An instant, concurrent, secure and lightweight sandbox runtime for AI Agents. Built with RustVMM and KVM, it achieves the perfect balance of security and performance: → Sub-60ms cold start (2.5-50x faster) → Under 5MB memory overhead per instance (6x less memory) → Dedicated kernel per sandbox (hardware-level isolation) → Thousands of concurrent sandboxes per node → 100% E2B SDK compatible. Swap the endpoint, zero code changes Full-stack capability, one-click deployment. 3 steps to spin up your own private AI sandbox 👇 🔗 https://t.co/zyxiP2A92W
