The Frontier
DeepSeek shows the machine that trains its agents — and it runs 3 million sandboxes a day
While Western labs debate whether their agents are safe in theory, DeepSeek just published the factory floor. A new paper, "DeepSeek Elastic Compute (DSec): A Sandbox Infrastructure for Effective Agentic Training at Scale" (arXiv:2609.22978), lays out the production system behind the lab's agentic reinforcement learning — and founder Liang Wenfeng is the last-listed author of the 162-author submission. The scale is the story: a single production unit spans roughly 160 nodes serving about 3 milli
