How DeepSeek V4’s CSA+HCA Architecture Turns Million‑Token Context into a Cheap Feature
DeepSeek V4 introduces a hybrid CSA/HCA attention mechanism and a Mixture‑of‑Experts design that reduces inference cost to 27% of its predecessor, enables a 1‑million‑token context as a standard feature, and runs efficiently on both NVIDIA GPUs and Huawei Ascend NPU, dramatically lowering the barrier for Java developers to integrate large‑scale AI.
