DeepSeek V4’s Silent Launch: 1.6 T Parameters, Triple Innovation, and Redefined Accessibility

DeepSeek V4 quietly debuted with a 1.6‑trillion‑parameter MoE model, introducing CSA+HCA compressed attention, mHC manifold‑constrained hyperconnections, and the Muon optimizer, achieving 1M‑token context at a quarter of V3’s cost, top Codeforces and LiveCodeBench scores, a 1/7 Opus price, MIT open‑source licensing, and dual‑stack Ascend NPU/NVIDIA GPU support.
