DeepSeek is significantly expanding its elastic computing team, particularly seeking senior engineers to manage its DSec sandbox infrastructure. This system supports the training, evaluation, and preprocessing for DeepSeek's V3.2 through V4.1 models, handling millions of sandbox instances daily. DSec has implemented several optimizations, including a three-layer environment structure, on-demand image loading, memory sharing, and intelligent CPU scheduling, to reduce resource consumption and increase concurrency. The infrastructure also supports diverse execution backends like Container, MicroVM, and Full VM, and is evolving to use agents to build environments for other agents, with ongoing efforts to enhance security against model exploits.
