DeepSeek describes DSec, the sandbox platform behind its agent training

A rare look at the infrastructure side of agent training.

A DeepSeek technical report describes DSec, a production platform that runs function-call, container, microVM and full-VM sandboxes through one SDK for large-scale reinforcement-learning of agents.

What hidden risk could pull against this, even if the news is good?

DSec runs agents in enormous numbers of sandboxes while they practice using tools. At that scale any isolation gap will be found, and training is exactly where agents are rewarded for being resourceful.

What hidden risk could pull against this, even if the news is good?

Reinforcement learning rewards outcomes the environment can check. If a sandbox lets an agent pass a check the wrong way, training can teach the shortcut instead of the skill.
