+# Online serving Example of vLLM-Omni for MiMo-Audio
+
+Source <https://github.com/vllm-project/vllm-omni/tree/main/examples/online_serving/mimo_audio>.
+
+
+## 🛠️ Installation
+
+Please refer to [README.md](https://github.com/vllm-project/vllm-omni/tree/main/README.md)
+
+## Run examples (MiMo-Audio)
+
+### Launch the Server
+```bash
+export MIMO_AUDIO_TOKENIZER_PATH="XiaomiMiMo/MiMo-Audio-Tokenizer"
+
+vllm-omni serve XiaomiMiMo/MiMo-Audio-7B-Instruct --omni \
+--served-model-name "MiMo-Audio-7B-Instruct"  \
+--port 18091 --stage-configs-path ./vllm_omni/model_executor/stage_configs/mimo_audio.yaml \
+--chat-template ./examples/online_serving/mimo_audio/chat_template.jinja
+```
+> ⚠️ **Important**  
+> **MiMo-Audio is not compatible with the default chat template.**  
+> The provided `chat_template.jinja` implements MiMo-specific role, audio token, and instruction formatting and **must be used for all inference**.
+
+
+### Send Multi-modal Request
+
+Get into the example folder
+```bash
+cd examples/online_serving/mimo_audio
+```
+
+####  Send request via python
+
+```bash
+# Audio dialogue task
+python openai_chat_completion_client_for_multimodal_generation.py \
+--query-type multi_audios \
+--message-json ../../offline_inference/mimo_audio/message_base64_wav.json
+```
+
+The Python client supports the following command-line arguments:
+
+- `--query-type` (or `-q`): Query type (default: `multi_audios`)
+  - Options: `multi_audios`, `text`
+- `--message-json` (or `-m`): Path to `base64` multi rounds audio messages json file
+  - Do not pass any value for "text" query type
+  - Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs, only for "Are these two audio clips the same?" task
+  - Example: `---message-json ./examples/offline_inference/mimo_audio/message_base64_wav.json`
+- `--prompt` (or `-p`): Custom text prompt/question, only for query type is "text"(TTS task)
+  - Attention! Do not pass any value for "multi_audios" query type
+  - Example: `--prompt "What are the main activities shown in this video?"`
+
+
+For example, to use multi rounds audios with local files:
+
+```bash
+python openai_chat_completion_client_for_multimodal_generation.py \
+--query-type multi_audios \
+--message-json ../../offline_inference/mimo_audio/message_base64_wav.json
+```
