DeepSeek details DSec sandbox infrastructure for agent training

DeepSeek published an arXiv paper on DSec (DeepSeek Elastic Compute), a sandbox platform for large-scale agent training. A production-scale unit spans about 160 nodes, supports roughly 3 million sandboxes per day and over 380,000 concurrent sandboxes, creating more than 5,000 per second. Founder Liang Wenfeng is among the paper's 130-plus authors.

• DSec unifies function-call, container, microVM and full-VM sandboxes
• One production unit: ~160 nodes, up to 3 million sandboxes per day
• Over 380,000 concurrent sandboxes and 5,000+ created per second
