Tencent open-sources CubeSandbox v0.7.0, keeping thousands of agents alive through node failures
SucceededMind · x · 2026-09-03
Tencent Cloud released CubeSandbox v0.7.0, fully open source, moving agent runtimes to Kubernetes-native workloads with strict state preservation. When a node fails, the system automatically resumes execution from the exact interrupt point while preserving full execution context, scaling from prototype to real-world clusters supporting thousands of agents. Commenters note that surviving node death without losing context is what most agent runtimes still fake.
