DeepSeek Expands Elastic Compute Team, Reveals DSec Sandbox Details
KEY FACTS
- DeepSeek's elastic compute team is hiring heavily, with a focus on senior engineers.
- A single DSec shard runs about 160 servers, 30,000 CPU cores, and 250TB of memory.
- That shard serves roughly 3 million sandboxes per day, with peak concurrent online sessions exceeding 380,000.
- DSec supports all of DeepSeek-V4's training, evaluation, and data preprocessing pipelines.
- DeepSeek plans to expand the number and variety of Agent environments by hundreds to thousands of times.

PHYSIX OBSERVATION
DeepSeek has turned Agent sandboxes into standalone infrastructure, overselling by 50x and loading images on demand, which shows that large-model training is shifting from stacking GPUs to competing on environment supply efficiency. Expanding the elastic compute team is laying the groundwork in advance for another hundredfold scale-up of Agents, and the environment layer may become the focus of competition in the next stage.
