@nash_su: Last night I was chatting with @i5ting about how a sandbox is an indispensable part of any agent, and today Tencent open-sourced Cube Sandbox: 1. Blazing-fast boot (<60 ms) thanks to snapshot cloning and warm resource pools 2. Hardware-grade security via KVM micro-VMs + eBPF network isolation, battle-tested on Tencent Cloud 3. Ultra-high density—runs in <5 MB RAM, thousands per node 4. E2B-compatible
