+# vLLM API
+
+To save the reinitialization time, it is great to use vLLM API instead of the original vLLM integration.
+You can use openAI like API server, but you can use vLLM API server as well to get a full feature of vLLM.
+
+## Start the vLLM API server
+
+In your vLLM installed machine, start vLLM API server like below.
+
+```bash
+vllm serve Qwen/Qwen2.5-14B-Instruct-AWQ -q awq --port 8012
+```
+
+You can find the detail about vLLM API server at the [vLLM documentation](https://docs.vllm.ai/en/stable/getting_started/quickstart.html#openai-compatible-server).
+
+## **Module Parameters**
+
+- **llm**: You can type your 'model name' at here. For example, `facebook/opt-125m`
+  or `mistralai/Mistral-7B-Instruct-v0.2`.
+- **uri**: The URI of the vLLM API server.
+- **max_tokens**: The maximum number of tokens. Default is 4096. Consider using longer tokens for longer prompts.
+- **temperature**: The temperature of the sampling. Higher temperature means more randomness.
+And support all parameters from vLLM API.
+
+## **Example config.yaml**
+
+```yaml
+ - module_type: vllm_api
+   uri: http://localhost:8012
+   llm: Qwen/Qwen2.5-14B-Instruct-AWQ
+   temperature: [0, 0.5]
+   max_tokens: 400
+```
