DeepDive into DeepSeek‑V4: Efficient Million‑Token Context, Hybrid Attention, and Muon Optimizer
The article provides an in‑depth technical analysis of DeepSeek‑V4, detailing its novel hybrid attention architecture (CSA and HCA), the manifold‑constrained hyper‑connection (mHC), massive KV‑cache reductions, FLOPs savings across token lengths, and the Muon optimizer with Newton‑Schulz orthogonalization, all backed by concrete benchmark tables and code snippets.
