DeepSeek-V4-Pro#
1 Introduction#
DeepSeek-V4 introduces several key upgrades over DeepSeek-V3:
The Manifold-Constrained Hyper-Connections (mHC) to strengthen conventional residual connections.
A hybrid attention architecture, which greatly improves long-context efficiency through Compress-4-Attention and Compress-128-Attention. For the Mixture-of-Experts (MoE) components, it still adopts the DeepSeekMoE architecture, with only minor adjustments.
DeepSeek-V4-Pro, the maximum reasoning effort mode of DeepSeek-V4, significantly advances the knowledge capabilities of open-source models, firmly establishing itself as the best open-source model available today. It achieves top-tier performance in coding benchmarks and significantly bridges the gap with leading closed-source models on reasoning and agentic tasks.
本文档将展示该模型的主要验证步骤,包括支持特性、特性配置、环境准备、单节点和多节点部署、精度及性能评估。
Note: Please replace the version placeholder above with your actual validation version.
2 Supported Features#
Refer to supported features to get the model's supported feature matrix.
Refer to feature guide to get the feature's configuration.
3 Prerequisites#
3.1 Model Weight#
DeepSeek-V4-Pro-w4a8-mtp(Quantized version): requires 2 Atlas 800 A3 (128G × 8) nodes or 4 Atlas 800 A2 (64G × 8) nodes. Download model weight
It is recommended to download the model weight to the shared directory of multiple nodes, such as /root/.cache/.
3.2 Verify Multi-node Communication (Optional)#
If you want to deploy a multi-node environment, you need to verify multi-node communication according to verify multi-node communication environment.
4 Installation#
4.1 Docker Image Installation#
Select an image based on your machine type and start the docker image on your node, refer to using docker.
Start the docker image on each node.

Key Parameter Descriptions:
--data-parallel-start-rankspecifies the starting data parallel rank of the current node. Each node must be set to a unique value (e.g., Node0 = 0, Node1 = 1).--data-parallel-addressspecifies the IP address of the data parallel master node (Node0). It must be consistent across all nodes.--headless(used on non-master nodes) disables the API server on the node, since only the master node serves requests.--max-model-lenspecifies the maximum context length. Adjust it according to your actual scenario.--speculative-configconfigures the MTP (Multi-Token Prediction) speculative decoding to accelerate inference.--compilation-config '{"cudagraph_mode":"FULL_DECODE_ONLY"}'enables full ACL graph execution in the decode phase to reduce scheduling latency.--async-schedulingenables asynchronous scheduling to overlap CPU scheduling with NPU computation.VLLM_ASCEND_ENABLE_FLASHCOMM1=1enables the FlashComm communication optimization.
Common Issues Tip: If you encounter issues, please refer to the Public FAQ for troubleshooting.

5.2 Multi-Node PD Separation Deployment#
We recommend using Mooncake for deployment: Mooncake.
In the standard deployment mode, Prefill (prompt processing) and Decode (token generation) tasks run on the same set of NPUs. PD (Prefill-Decode) separation addresses this by running Prefill and Decode on dedicated node groups, each configured independently. This architecture is recommended for production deployments with concurrent multi-user workloads, where stable latency and high throughput are both required.
The following sections describe PD separation deployment on both Atlas 800 A3 (128G × 8) and Atlas 800 A2 (64G × 8) multi-node environments.
5.2.1 A3 Series PD Separation Deployment#
This section shows the deployment guide of DeepSeek-V4-Pro on Atlas 800 A3 (128G × 8) multi-node environment with 1P1D for better performance.

Deploy the P-D disaggregation proxy.
Refer to Prefill-Decode Disaggregation (Deepseek) to deploy the P-D disaggregation proxy.
Key Parameter Descriptions:
VLLM_ASCEND_ENABLE_FLASHCOMM1=1: enables the communication optimization function on the prefill nodes.VLLM_ASCEND_ENABLE_FUSED_MC2=1: enables the Fused MC2 fusion operator to accelerate communication on prefill nodes (A3 series).recompute_scheduler_enable: true: enables the recomputation scheduler. When the KV Cache of the decode node is insufficient, requests will be sent to the prefill node to recompute the KV Cache. In the PD separation scenario, it is recommended to enable this configuration on decode nodes.MooncakeHybridConnector: the KV transfer connector used for PD separation, transferring KV Cache between prefill and decode nodes.enable_shared_expert_dp: true: enables data parallelism for shared experts, applicable to MoE models.
Deployment Verification:
After the PD separation service is fully started, send a request through the proxy port on the prefill master node to verify that Prefill and Decode nodes are working correctly together. Refer to Prefill-Decode Disaggregation (Deepseek) for the proxy verification method.
Common Issues Tip: If you encounter issues with PD separation deployment, please refer to the Public FAQ for troubleshooting.
6 Functional Verification#
服务器启动后,您可以使用输入提示查询模型:
In <node0_ip>:
curl http://<node0_ip>:<port>/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "dsv4",
"messages": [
{
"role": "user",
"content": "Who are you?"
}
],
"max_tokens": 256,
"temperature": 0
}'
Expected Result:
The service returns HTTP 200 OK with a JSON response containing the choices field.

9 Performance Tuning#
9.1 Recommended Configurations#
Note: The following configurations are validated in specific test environments and are for reference only. The optimal configuration depends on factors such as maximum input/output length, prefix cache hit rate, precision requirements, and deployment machine ratios. It is recommended to refer to Section 9.2 for tuning based on actual conditions.

For complete startup commands and parameter descriptions, please refer to the deployment examples in Chapter 5.
Notice:
max-model-len and max-num-seqs need to be set according to the actual usage scenario. For other settings, please refer to the Deployment chapter.
Currently, we support 4K prefix cache hit in an experimental manner. You only need to change the value of --block-size from 128 to 32 in the service.
