+# Use Models From ModelScope
+
+To use a model from [ModelScope](https://www.modelscope.cn), set the environment variable `SGLANG_USE_MODELSCOPE`.
+
+```bash
+export SGLANG_USE_MODELSCOPE=true
+```
+
+We take [Qwen2-7B-Instruct](https://www.modelscope.cn/models/qwen/qwen2-7b-instruct) as an example. Launch the Server:
+---
+
+```bash
+python -m sglang.launch_server --model-path qwen/Qwen2-7B-Instruct --port 30000
+```
+
+Or start it by docker:
+
+```bash
+docker run --gpus all \
+    -p 30000:30000 \
+    -v ~/.cache/modelscope:/root/.cache/modelscope \
+    --env "SGLANG_USE_MODELSCOPE=true" \
+    --ipc=host \
+    lmsysorg/sglang:latest \
+    python3 -m sglang.launch_server --model-path Qwen/Qwen2.5-7B-Instruct --host 0.0.0.0 --port 30000
+```
+
+Note that modelscope uses a different cache directory than huggingface. You may need to set it manually to avoid running out of disk space.
