DeepSeek Discloses DSec, a Sandbox Platform for Training AI Agents at Scale

DeepSeek has published DeepSeek Elastic Compute, or DSec, a production sandbox platform designed to train and evaluate AI agents at very large scale while containing failures such as reward hacking, filesystem damage and runaway resource use. The system is described in a September 19 paper as infrastructure for stateful agent workloads, not a new foundation model, and is built to let models inspect repositories, call tools, execute commands and interact with services inside isolated environments.
