+# Ming-flash-omni 2.0
+
+[Ming-flash-omni-2.0](https://github.com/inclusionAI/Ming) is an omni-modal model supporting text, image, video, and audio understanding, with outputs in text, image, and audio. For now, Ming-flash-omni-2.0 in vLLM-Omni is supported with thinker stage (multi-modal understanding).
+
+## Setup
+
+Please refer to the [stage configuration documentation](https://docs.vllm.ai/projects/vllm-omni/en/latest/configuration/stage_configs/) to configure memory allocation appropriately for your hardware setup.
+
+## Run examples
+
+### Text-only
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type text
+```
+
+#### Reasoning (Thinking Mode)
+
+Reasoning (Thinking) mode is enabled via applying "detailed thinking on" when building the system prompt template (in `apply_chat_template`).
+
+In the end2end example, a default problem for thinking mode is provided, as referred to the example usage of Ming's cookbook;
+To utilize it, you have to download the example figure from https://github.com/inclusionAI/Ming/blob/3954fcb880ff5e61ff128bcf7f1ec344d46a6fe3/figures/cases/3_0.png
+
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py -q reasoning --image-path ./3_0.png
+```
+
+### Image understanding
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_image
+
+# With a local image
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_image --image-path /path/to/image.jpg
+```
+
+### Audio understanding
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_audio
+
+# With a local audio file
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_audio --audio-path /path/to/audio.wav
+```
+
+### Video understanding
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_video
+
+# With a local video and custom frame count
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_video --video-path /path/to/video.mp4 --num-frames 16
+```
+
+### Mixed modalities (image + audio)
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_mixed_modalities \
+    --image-path /path/to/image.jpg \
+    --audio-path /path/to/audio.wav
+```
+
+If media file paths are not provided, the script uses built-in default assets.
+
+### Modality control
+To control output modalities (e.g. text-only output):
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_audio --modalities text
+```
+
+*For now, only text output is supported*
+
+### Custom stage config
+```bash
+python examples/offline_inference/ming_flash_omni/end2end.py --query-type use_image \
+    --stage-configs-path /path/to/your_config.yaml
+```
