hq720.jpg Using the models by way of these platforms is a good various to using them immediately by means of the DeepSeek Chat and APIs. These platforms make sure the reliability and safety of their hosted language fashions. DeepSeek Ai Chat Windows receives common updates to enhance efficiency, introduce new options, and improve safety. House has introduced the "No DeepSeek on Government Devices Act" to ban federal employees from using the DeepSeek app on authorities units, citing national security considerations. 1. Review app permissions: Regularly verify and update the permissions you’ve granted to AI purposes. DeepSeek: Released as a free-to-use chatbot app on iOS and Android platforms, DeepSeek has surpassed ChatGPT as the top Free DeepSeek r1 app on the US App Store. DeepSeek LLM. Released in December 2023, that is the primary model of the company's normal-purpose mannequin. Comprising the DeepSeek LLM 7B/67B Base and DeepSeek LLM 7B/67B Chat - these open-source models mark a notable stride ahead in language comprehension and versatile software.


单个 forward 和 backward chunk 的重叠策略(原报告第 12页)。本文将从性能、架构、工程、预训练和后训练五个维度来拆解 V3,所用到的图表、数据源于技术报告:《DeepSeek-V3 Technical Report》。 Eight 个 PP rank 和 20 个 micro-batch 的 DualPipe 调度示例(原报告第 13页)。 Warp 专业化 (Warp Specialization): 将不同的通信任务 (例如 IB 发送、IB-to-NVLink 转发、NVLink 接收等) 分配给不同的 Warp,并根据实际负载情况动态调整每个任务的 Warp 数量,实现了通信任务的精细化管理和优化。自动调整通信块大小: 通过自动调整通信块的大小,减少了对 L2 缓存的依赖,降低了对其他计算内核的干扰,进一步提升了通信效率。


经过指令微调后,DeepSeek-V3 的性能进一步提升。 CPU 上的 EMA (Exponential Moving Average): DeepSeek online-V3 将模型参数的 EMA 存储在 CPU 内存中,并异步更新。 DualPipe 在流水线气泡数量和激活内存开销方面均优于 1F1B 和 ZeroBubble 等现有方法。这种策略避免了在 GPU 上存储 EMA 参数带来的额外显存开销。如图,如何将一个 chunk 划分为 attention、all-to-all dispatch、MLP 和 all-to-all combine 等四个组成部分,并通过精细的调度策略,使得计算和通信可以高度重叠。 DeepSeek-V3 通过一系列精细的优化策略,有效地缓解了这一瓶颈。 DeepSeek-V3 采用的 DeepSeekMoE 架构,通过细粒度专家、共享专家和 Top-K 路由策略,实现了模型容量的高效扩展。


这种稀疏激活的机制,使得 DeepSeek-V3 能够在不显著增加计算成本的情况下,拥有庞大的模型容量。 MLA 通过将 Key (K) 和 Value (V) 联合映射至低维潜空间向量 (cKV),显著降低了 KV Cache 的大小,从而提升了长文本推理的效率。 DeepSeek-V3 采用了一种名为 DualPipe 的创新流水线并行策略。 DeepSeek-V3 的这次发布,伴随三项创新:Multi-head Latent Attention (MLA)、DeepSeekMoE 架构以及无额外损耗的负载均衡策略。该策略的偏置项更新速度 (γ) 在预训练的前 14.3T 个 Token 中设置为 0.001,剩余 500B 个 Token 中设置为 0.0;序列级平衡损失因子 (α) 设置为 0.0001。
