DeepSeek published an arXiv paper describing DSec, a production sandbox platform for large-scale agent training. A single unit spans about 160 nodes, handles roughly 3 million sandboxes daily and over 380,000 concurrently, creating more than 5,000 per second. DSec unifies function-call, container, microVM and full-VM backends and coordinates sandbox lifecycle with reinforcement learning workloads. Founder Liang Wenfeng is among 130-plus authors.
