+Setup environment variables:
+
+```bash
+# Set `max_split_size_mb` to reduce memory fragmentation and avoid out of memory
+export PYTORCH_NPU_ALLOC_CONF=max_split_size_mb:256
+```
+
+Download the model:
+
+```bash
+git lfs install
+git clone https://gitcode.com/ascend-tribe/pangu-pro-moe-model.git
+```
+
+### Online Inference on Multi-NPU
+
+Run the following script to start the vLLM server on Multi-NPU:
+
+```bash
+vllm serve /path/to/pangu-pro-moe-model \
+--tensor-parallel-size 4 \
+--trust-remote-code \
+--enforce-eager
+```
+
+Once your server is started, you can query the model with input prompts:
+
+```bash
+export question="你是谁？"
+curl http://localhost:8000/v1/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "prompt": "[unused9]系统：[unused10][unused9]用户：'${question}'[unused10][unused9]助手：",
+    "max_tokens": 64,
+    "top_p": 0.95,
+    "top_k": 50,
+    "temperature": 0.6
+  }'
+```
+

+### Offline Inference on Multi-NPU
+
+Run the following script to execute offline inference on multi-NPU:
