了解 DeepSeek v4 的功能、特性以及它如何帮助您获得更好的效果。
高效的万亿级架构
DeepSeek v4 代表了 Mixture-of-Experts (MoE) 设计的演进，总参数扩展至 1.6 万亿，激活参数为 490 亿。该模型集成了 Compressed Sparse Attention (CSA) 和 Heavily Compressed Attention (HCA) 以管理其 100 万 token 的 context window。与标准架构相比，这些技术将 KV cache 内存占用减少了 90%，从而实现了更快的 inference，并降低了长 context 任务的硬件要求。
原生 Multimodal 集成
与那些使用独立视觉或音频编码器的模型不同，DeepSeek v4 从最初的训练阶段就是原生 multimodal 的。它在统一框架内处理文本、图像、音频和视频。这种方法改进了跨模态的 reasoning，使模型能够对原始视频文件和大型文档档案进行复杂分析，而不会丢失精细细节。
战略性成本颠覆
该模型定位为高性能的 open-source 替代品，用以取代顶级的私有模型。其定价为每百万输入 tokens 1.74 美元，在 coding 和数学领域保持了 frontier 级别的性能，同时显著降低了开发者的运营成本。包含可选的 Thinking Mode，允许对逻辑证明和竞赛编程进行深度 reasoning。
