+# Run Ollama on Intel GPU
+
+### 1 Install Ollama integrated with IPEX-LLM
+
+First ensure that IPEX-LLM is installed. Follow the instructions on the [IPEX-LLM Installation Quickstart for Windows with Intel GPU](install_windows_gpu.html). And activate your conda environment.
+
+Run `pip install --pre --upgrade ipex-llm[cpp]`, then execute `init-ollama`, you can see a softlink of `ollama`under your current directory.
+
+### 2 Verify Ollama Serve
+
+To avoid potential proxy issues, run `export no_proxy=localhost,127.0.0.1`. Execute `export ZES_ENABLE_SYSMAN=1` and `source /opt/intel/oneapi/setvars.sh` to enable driver initialization and dependencies for system management.
+
+Start the service using `./ollama serve`. It should display something like:

+
+To expose the `ollama` service port and access it from another machine, use `OLLAMA_HOST=0.0.0.0 ./ollama serve`.
+
+Open another terminal, use `./ollama pull <model_name>` to download a model locally.

+
+Verify the setup with the following command:
+
+```shell
+curl http://localhost:11434/api/generate -d '
+{ 
+  "model": "<model_name>", 
+  "prompt": "Why is the sky blue?", 
+  "stream": false 
+}'
+```
+
+Expected results:

+
+### 3 Example: Ollama Run
+
+You can use `./ollama run <model_name>` to automatically pull and load the model for a stream chat.
