DSec provides a unified SDK for FnCall, container, microVM, and full-VM sandboxes, enabling elastic execution across 160 nodes that serves 3 million sandboxes daily and supports 5,000 creations per second.
The platform reduces environment setup overhead, improves memory efficiency, and maintains low latency under high-density workloads, which is critical for reliable agentic training at scale.

DSec unifies multiple sandbox backends through a single SDK for consistent developer access.
It manages placement and lifecycle across a 160-node cluster, supporting millions of sandboxes daily.
Integration with Fire-Flyer File System enables on-demand image loading and memory-efficient execution.
THE READ
What the cluster adds up to.
The paper introduces DSec as a production sandbox platform that replaces isolated runtimes with an elastic execution environment for agentic training workloads.
Adopting DSec requires engineering teams to integrate its unified SDK and adapt deployment pipelines to coordinate sandbox lifecycle with GPU training cycles.
The platform's design stops working for workloads that do not benefit from stateful, isolated execution or that do not leverage the Fire-Flyer File System's on-demand image loading.
