teortaxesTex notes DeepSeek has had a security effort, DSec, since early 2026 (around V4-preview, February). By V4.1 it ran multiple scale units — at least five, inferred from "millions of concurrent sandboxes" at 380K per unit. Only now is the effort expanding, and onboarding people will take a while.
