今日精讲DeepSeek V4 报告太详尽了！484 天换代之路全公开今日精讲 ①：量子位逐条对照 DeepSeek V4 技术报告。V4-Pro 1.6T 参数 / 49B 激活，V4-Flash 284B / 13B，1M 上下文标配，单 token FLOPs 砍到 V3.2 的 27%、KV cache 只剩 10%。架构动了三处：mHC（流形约束超连接）把残差流约束到双随机矩阵的 Birkhoff polytope 上，谱范数硬上限不爆炸；CSA / HCA 混合稀疏注意力交替叠加，CSA 先压再选 top-k、HCA 直接 128 倍硬压做全局信号；Muon 主优化器接管绝大多数参数，AdamW 只留给 embedding 和 RMSNorm。后训练把传统 mixed RL 换成 OPD（On-Policy Distillation）+ 三档推理强度。Codeforces ...去小宇宙查看完整单集简介前往小宇宙评论区与主播互动
