# Stage configs for vLLM-Omni
In vLLM-Omni, the target model is separated into multiple stages, which are processed by different LLMEngines, DiffusionEngines or other types of engines. Depending on different types of stages, such as Autoregressive (AR) stage or Diffusion transformer (DiT) stage, each can choose corresponding schedulers, model workers to load with the Engines in a plug-in fashion.
!!! note
Default stage config YAMLs (for example, `vllm_omni/model_executor/stage_configs/qwen2_5_omni.yaml` and `vllm_omni/model_executor/stage_configs/qwen3_omni_moe.yaml`) are bundled and loaded automatically when `stage_configs_path` is not provided. They have been verified to work on 1xH100 for Qwen2.5-Omni and 2xH100 for Qwen3-Omni.
Therefore, as a core part of vLLM-Omni, the stage configs for a model have several main functions:
- Claim partition of stages and their corresponding class implementation in `model_executor/models`.
- The disaggregated configuration for each stage and the communication topology among them.
- Engine arguments for each engine within the stage.
- Input and output dependencies for each stage.
- Default input parameters.
If users want to modify some part of it. The custom stage_configs file can be input as input argument in both online and offline. Just like examples below:
For offline (Assume necessary dependencies have ben imported):
```python
model_name = "Qwen/Qwen2.5-Omni-7B"
omni_llm = OmniLLM(model=model_name, stage_configs_path="/path/to/custom_stage_configs.yaml")
```
For online serving:
```bash
vllm serve Qwen/Qwen2.5-Omni-7B --omni --port 8091 --stage-configs-path /path/to/stage_configs_file
```
!!! important
We are actively iterating on the definition of stage configs, and we welcome all feedbacks from both community users and developers to help us shape the development!
Below is a specific example of stage_configs.yaml in Qwen2.5-omni.
```python

## Stage Configuration Arguments
Each stage in the `stage_args` list contains the following configuration options:
### `stage_id`
A unique identifier for each stage in the multi-stage pipeline. Stages are numbered sequentially starting from 0, and this ID is used to reference stages in inter-stage dependencies (e.g., `engine_input_source`).
### `runtime`
Configuration for disaggregated execution of the stage, controlling how the stage is deployed and executed.
#### `runtime.process`
Whether to run this stage in a separate process. When set to `true`, the stage will be executed in an isolated process, enabling better resource isolation and parallel execution across different stages. This is essential for multi-GPU deployments where different stages run on different devices.
Default: `true`
#### `runtime.devices`
Visible devices for this stage, specified as a string. This controls which GPU devices are available to the stage process, similar to setting `CUDA_VISIBLE_DEVICES` or using `torch.cuda.set_device()`. For example, `"0"` uses GPU 0, `"1"` uses GPU 1, and `"0,1"` makes both GPUs 0 and 1 visible.
Default: `"0"`
#### `runtime.max_batch_size`
The maximum batch size for offline inference in this stage. This limits how many sequences can be processed together in a single batch during offline inference operations.
Default: `1`
### `engine_args`
Engine arguments for configuring the LLM engine, diffusion engine, or other engine types used by this stage.
#### `engine_args.model_stage`
The name identifier for this model stage within the multi-stage architecture. This is used internally to distinguish different stages of the same model (e.g., "thinker", "talker", "code2wav" in Qwen2.5-Omni).
#### `engine_args.model_arch`
The model architecture class name that is registered in `model_executor/models/registry.py`. This specifies which model implementation to use for this stage. The class must be registered in the model registry for vLLM-Omni to locate and instantiate it.
#### `engine_args.worker_cls`
The specific worker class to use for this stage. This determines how the model computations are executed. Examples include `vllm_omni.worker.gpu_ar_worker.GPUARWorker` for autoregressive stages and `vllm_omni.worker.gpu_diffusion_worker.GPUDiffusionWorker` for diffusion-based stages.
#### `engine_args.scheduler_cls`
The scheduler class to use for this stage. The scheduler manages request queuing, batching, and execution order. Examples include `vllm_omni.core.sched.scheduler.OmniScheduler` for standard stages and `vllm_omni.core.sched.diffusion_scheduler.DiffusionScheduler` for diffusion stages.
#### `engine_args.gpu_memory_utilization`
The fraction of GPU memory to allocate for this stage within a single GPU chip. This is a value between 0.0 and 1.0, where 0.8 means 80% of the GPU memory will be used by this stage. This allows fine-grained control over memory allocation when multiple stages share the same GPU or when reserving memory for other operations.
Default: `0.8`
#### `engine_args.enforce_eager`
Whether to enforce eager execution mode. When set to `true`, the engine will run in eager mode without using CUDA graphs or other compilation optimizations. Currently, vLLM-Omni only supports eager mode.
Default: `true`
#### `engine_args.trust_remote_code`
Whether to trust remote code when loading models from Hugging Face. This is required for models that use custom code in their configuration files. Set to `true` when loading models that require custom model implementations.
Default: `true`
#### `engine_args.engine_output_type`
Specifies the type of output produced by this stage's engine. This determines what kind of data flows to downstream stages. Possible values include `latent` (hidden states), `text` (tokenized text), and `audio` (audio waveforms). When set to `latent`, the stage outputs latent hidden states in addition to token IDs, which are consumed by downstream stages.
Default: `latent`
#### `engine_args.enable_prefix_caching`
Whether to enable prefix caching for this stage. Prefix caching can improve performance by caching KV cache for common prompt prefixes. However, for requests that output hidden states (when `engine_output_type` is `latent`), prefix caching is not currently supported and should be set to `false`.
Default: `false`
### `is_comprehension`
Whether this stage is a text or multimodal comprehension module. When set to `true`, the stage acts as a comprehension module that processes input text or multimodal content. If this is the first comprehension stage, `AsyncOmni` will use its tokenizer as the default tokenizer for the entire pipeline.
Default: `true`
### `final_output`
Whether this stage produces output that is part of the final outputs returned to the user. When set to `false`, the stage only works as an intermediate stage, processing data that flows to downstream stages but not contributing directly to the final response.
Default: `true`
### `final_output_type`
The type of final output produced by this stage. This specifies what format the output will be in when returned to the user. Currently supported values are `text` (for text generation) and `audio` (for audio generation).
Default: `text`
### `default_sampling_params`
Default sampling parameters for this stage. These parameters control the generation behavior and align with vLLM's sampling parameter semantics. These defaults are used when no explicit sampling parameters are provided in the request.
#### `default_sampling_params.temperature`
Sampling temperature for controlling randomness. Lower values (e.g., 0.0) make the output more deterministic and focused, while higher values increase randomness.
Default: `0.0`
#### `default_sampling_params.top_p`
Nucleus sampling parameter. Only tokens with cumulative probability mass up to `top_p` are considered. This helps filter out low-probability tokens while maintaining diversity.
Default: `1.0`
#### `default_sampling_params.top_k`
Top-k sampling parameter. Only the top `k` most likely tokens are considered. Set to `-1` to disable top-k filtering and consider all tokens.
Default: `-1`
#### `default_sampling_params.max_tokens`
Maximum number of tokens to generate in this stage. This limits the length of the output sequence.
Default: `2048`
#### `default_sampling_params.seed`
Random seed for reproducible generation. When set, the random number generator will be initialized with this seed to ensure consistent outputs across runs.
Default: `42`
#### `default_sampling_params.detokenize`
Whether to detokenize the output tokens into text. When set to `true`, token IDs are converted back to readable text strings.
Default: `True`
#### `default_sampling_params.repetition_penalty`
Penalty applied to tokens that have already appeared in the generated sequence. Values greater than 1.0 discourage repetition, while values less than 1.0 encourage it. A value of 1.0 applies no penalty.
Default: `1.1`

vLLM-Omni depends vLLM. So please follow instructions below mainly for vLLM.
!!! note
PyTorch installed via `conda` will statically link `NCCL` library, which can cause issues when vLLM tries to use `NCCL`. See <gh-issue:8420> for more details.
In order to be performant, vLLM has to compile many cuda kernels. The compilation unfortunately introduces binary incompatibility with other CUDA versions and PyTorch versions, even for the same PyTorch version with different building configurations.
Therefore, it is recommended to install vLLM and vLLM-Omni with a **fresh new** environment. If either you have a different CUDA version or you want to use an existing PyTorch installation, you need to build vLLM from source. See [build-from-source-vllm](https://docs.vllm.ai/en/stable/getting_started/installation/gpu/#build-wheel-from-source) for more details.

vLLM-Omni offers an official docker image for deployment. These images are built on top of vLLM docker images and available on Docker Hub as [vllm/vllm-omni](https://hub.docker.com/r/vllm/vllm-omni/tags). The version of vLLM-Omni indicates which release of vLLM it is based on.
Here's an example deployment command that has been verified on 2 x H100's:
```bash
docker run --runtime nvidia --gpus 2 \
-v ~/.cache/huggingface:/root/.cache/huggingface \
--env "HF_TOKEN=$HF_TOKEN" \
-p 8091:8091 \
--ipc=host \
vllm/vllm-omni:v0.11.0rc1 \
--model Qwen/Qwen3-Omni-30B-A3B-Instruct --port 8091
```
!!! tip
You can use this docker image to serve models the same way you would with in vLLM! To do so, make sure you overwrite the default entrypoint (`vllm serve --omni`) which works only for models supported in the vLLM-Omni project.

It allows Markdown authors to use GitHub shorthand links like:

These are automatically rewritten into fully qualified GitHub URLs pointing to

# Supported Models
vLLM-Omni supports unified multimodal comprehension and generation models across various tasks.
## Model Implementation
If vLLM-Omni natively supports a model, its implementation can be found in <gh-file:vllm-omni/model_executor/models> and <gh-file:vllm_omni/diffusion/models>.

# Frequently Asked Questions
> Q: How many chips do I need to infer a model in vLLM-Omni?
A: Now, we support natively disaggregated deployment for different model stages within a model. There is a restriction that one chip can only has one AutoRegressive model stage. This is because the unified KV cache management of vLLM. Stages of other types can coexist with in a chip. The restriction will be resolved in later version.
> Q: When trying to run examples, I encounter error about backend of librosa or soundfile. How to solve it?
A: If you encounter error about backend of librosa, try to install ffmpeg with command below.
```
sudo apt update
sudo apt install ffmpeg
```
> Q: I encounter some bugs or CI problems, which is urgent. How can I solve it?
A: At first, you can check current [issues](https://github.com/vllm-project/vllm-omni/issues) to find possible solutions. If non of these satisfy your demand and it is urgent, please find these [volunteers](https://docs.vllm.ai/projects/vllm-omni/en/latest/community/volunteers/) for help.
> Q: Does vLLM-Omni support AWQ or any other quantization?
A: vLLM-Omni partitions model into several stages. For AR stages, it will reuse main logic of LLMEngine in vLLM. So current quantization supported in vLLM should be also supported in vLLM-Omni for them. But systematic verification is ongoing. For quantization for DiffusionEngine, we are working on it. Please stay tuned and welcome contribution!
> Q: Does vLLM-Omni support multimodal streaming input and output?
A: Not yet. We already put it on the [Roadmap](https://github.com/vllm-project/vllm-omni/issues/165). Please stay tuned!

#### Using Local Media Files
The `end2end.py` script supports local media files (audio, video, image) via CLI arguments:
```bash
# Use single local media files
python end2end.py --query-type use_image --image-path /path/to/image.jpg
python end2end.py --query-type use_video --video-path /path/to/video.mp4
python end2end.py --query-type use_audio --audio-path /path/to/audio.wav
# Combine multiple local media files
python end2end.py --query-type mixed_modalities \
--video-path /path/to/video.mp4 \
--image-path /path/to/image.jpg \
--audio-path /path/to/audio.wav
# Use audio from video file
python end2end.py --query-type use_audio_in_video --video-path /path/to/video.mp4
```
If media file paths are not provided, the script will use default assets. Supported query types:
- `use_image`: Image input only
- `use_video`: Video input only
- `use_audio`: Audio input only
- `mixed_modalities`: Audio + image + video
- `use_audio_in_video`: Extract audio from video
- `text`: Text-only query

#### Using Local Media Files
The `end2end.py` script supports local media files (audio, video, image) via command-line arguments:
```bash
# Use local video file
python end2end.py --query-type use_video --video-path /path/to/video.mp4
# Use local image file
python end2end.py --query-type use_image --image-path /path/to/image.jpg
# Use local audio file
python end2end.py --query-type use_audio --audio-path /path/to/audio.wav
```
If media file paths are not provided, the script will use default assets. Supported query types:
- `use_video`: Video input
- `use_image`: Image input
- `use_audio`: Audio input
- `text`: Text-only query

# Qwen-Image Offline Inference
Source <https://github.com/vllm-project/vllm-omni/tree/main/examples/offline_inference/qwen_image>.
This folder provides two simple entrypoints for experimenting with `Qwen/Qwen-Image` using vLLM-Omni:
- `text_to_image.py`: command-line script for single image generation.
- `web_demo.py`: lightweight Gradio UI for interactive prompt/seed/CFG exploration.
## Local CLI Usage
```bash
python text_to_image.py \
--prompt "a cup of coffee on the table" \
--seed 42 \
--cfg_scale 4.0 \
--num_images_per_prompt 1 \
--num_inference_steps 50 \
--height 1024 \
--width 1024 \
--output outputs/coffee.png
```
Key arguments:
- `--prompt`: text description (string).
- `--seed`: integer seed for deterministic sampling.
- `--cfg_scale`: true CFG scale (model-specific guidance strength).
- `--num_images_per_prompt`: number of images to generate per prompt (saves as `output`, `output_1`, ...).
- `--num_inference_steps`: diffusion sampling steps (more steps = higher quality, slower).
- `--height/--width`: output resolution (defaults 1024x1024).
- `--output`: path to save the generated PNG.
> ℹ️ Qwen-Image currently publishes best-effort presets at `1328x1328`, `1664x928`, `928x1664`, `1472x1140`, `1140x1472`, `1584x1056`, and `1056x1584`. Adjust `--height/--width` accordingly for the most reliable outcomes.
## Web UI Demo
Launch the gradio demo:
```bash
python gradio_demo.py --port 7862
```
Then open `http://localhost:7862/` on your local browser to interact with the web UI.

# Offline Example of vLLM-Omni for Qwen3-Omni
## 🛠️ Installation
Please refer to [README.md](../../../README.md)
## Run examples (Qwen3-Omni)
### Multiple Prompts
Download dataset from [seed_tts](https://drive.google.com/file/d/1GlSjVfSHkW3-leKKBlfrjuuTGqQ_xaLP/edit). For processing dataset please refer to [Qwen2.5-Omni README.md](../qwen2_5_omni/README.md)
Get into the example folder
```bash
cd examples/offline_inference/qwen3_omni
```
Then run the command below.
```bash
bash run_multiple_prompts.sh
```
### Single Prompt
Get into the example folder
```bash
cd examples/offline_inference/qwen3_omni
```
Then run the command below.
```bash
bash run_single_prompt.sh
```
If you have not enough memory, you can set thinker with tensor parallel. Just run the command below.
```bash
bash run_single_prompt_tp.sh
```
#### Using Local Media Files
The `end2end.py` script supports local media files (audio, video, image) via command-line arguments:
```bash
# Use local video file
python end2end.py --query-type use_video --video-path /path/to/video.mp4
# Use local image file
python end2end.py --query-type use_image --image-path /path/to/image.jpg
# Use local audio file
python end2end.py --query-type use_audio --audio-path /path/to/audio.wav
```
If media file paths are not provided, the script will use default assets. Supported query types:
- `use_video`: Video input
- `use_image`: Image input
- `use_audio`: Audio input
- `text`: Text-only query
### FAQ
If you encounter error about backend of librosa, try to install ffmpeg with command below.
```
sudo apt update
sudo apt install ffmpeg
```

# Qwen-Image Offline Inference
This folder provides two simple entrypoints for experimenting with `Qwen/Qwen-Image` using vLLM-Omni:
- `text_to_image.py`: command-line script for single image generation.
- `web_demo.py`: lightweight Gradio UI for interactive prompt/seed/CFG exploration.
## Local CLI Usage
```bash
python text_to_image.py \
--prompt "a cup of coffee on the table" \
--seed 42 \
--cfg_scale 4.0 \
--num_images_per_prompt 1 \
--num_inference_steps 50 \
--height 1024 \
--width 1024 \
--output outputs/coffee.png
```
Key arguments:
- `--prompt`: text description (string).
- `--seed`: integer seed for deterministic sampling.
- `--cfg_scale`: true CFG scale (model-specific guidance strength).
- `--num_images_per_prompt`: number of images to generate per prompt (saves as `output`, `output_1`, ...).
- `--num_inference_steps`: diffusion sampling steps (more steps = higher quality, slower).
- `--height/--width`: output resolution (defaults 1024x1024).
- `--output`: path to save the generated PNG.
> ℹ️ Qwen-Image currently publishes best-effort presets at `1328x1328`, `1664x928`, `928x1664`, `1472x1140`, `1140x1472`, `1584x1056`, and `1056x1584`. Adjust `--height/--width` accordingly for the most reliable outcomes.
## Web UI Demo
Launch the gradio demo:
```bash
python gradio_demo.py --port 7862
```
Then open `http://localhost:7862/` on your local browser to interact with the web UI.

# Online serving Example of vLLM-omni for Qwen2.5-omni
## 🛠️ Installation
Please refer to [README.md](../../README.md)
## Run examples (Qwen2.5-omni)
Launch the server
```bash
vllm serve Qwen/Qwen2.5-Omni-7B --omni --port 8091
```
If you have custom stage configs file, launch the server with command below
```bash
vllm serve Qwen/Qwen2.5-Omni-7B --omni --port 8091 --stage-configs-path /path/to/stage_configs_file
```
Get into the example folder
```bash
cd examples/online_serving
```
Send request via python
```bash
python openai_chat_completion_client_for_multimodal_generation.py --query-type mixed_modalities
```
Send request via curl
```bash
bash run_curl_multimodal_generation.sh mixed_modalities
```
### FAQ
If you encounter error about backend of librosa, try to install ffmpeg with command below.
```
sudo apt update
sudo apt install ffmpeg
```
## Run Local Web UI Demo
This Web UI demo allows users to interact with the model through a web browser.
### Running Gradio Demo
Once vllm and vllm-omni are installed, you can launch the web service built on AsyncOmniLLM by
```bash
python gradio_demo.py --model Qwen/Qwen2.5-Omni-7B --port 7861
```
Then open `http://localhost:7861/` on your local browser to interact with the web UI.
### Options
The gradio demo also supports running with an existing API server and can be customized with the following arguments.
```bash
python gradio_demo.py \
--model Qwen/Qwen2.5-Omni-7B \
--use-api-server \
--api-base http://localhost:8091/v1 \
--ip 127.0.0.1 \
--port 7861
```
- `--model`: Model name
- `--use-api-server`: If set, connect to an existing vLLM HTTP API server instead of running AsyncOmniLLM locally.
- `--api-base`: Base URL for vllm serve (only used when `use-api-server` is set, default: http://localhost:8091/v1)
- `--ip`: Host/IP for Gradio server (default: 127.0.0.1)
- `--port`: Port for Gradio server (default: 7861)
- `--stage-configs-path`: Path to custom stage configs YAML file (optional)
- `--share`: Share the Gradio demo publicly (creates a public link)

Get into the example folder
```bash
cd examples/online_serving/qwen2_5_omni
```
#### Send request via python
```bash
python openai_chat_completion_client_for_multimodal_generation.py --query-type mixed_modalities
```
The Python client supports the following command-line arguments:
- `--query-type` (or `-q`): Query type (default: `mixed_modalities`)
- Options: `mixed_modalities`, `use_audio_in_video`, `multi_audios`, `text`
- `--video-path` (or `-v`): Path to local video file or URL
- If not provided and query-type uses video, uses default video URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Example: `--video-path /path/to/video.mp4` or `--video-path https://example.com/video.mp4`
- `--image-path` (or `-i`): Path to local image file or URL
- If not provided and query-type uses image, uses default image URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Supports common image formats: JPEG, PNG, GIF, WebP
- Example: `--image-path /path/to/image.jpg` or `--image-path https://example.com/image.png`
- `--audio-path` (or `-a`): Path to local audio file or URL
- If not provided and query-type uses audio, uses default audio URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Supports common audio formats: MP3, WAV, OGG, FLAC, M4A
- Example: `--audio-path /path/to/audio.wav` or `--audio-path https://example.com/audio.mp3`
- `--prompt` (or `-p`): Custom text prompt/question
- If not provided, uses default prompt for the selected query type
- Example: `--prompt "What are the main activities shown in this video?"`
For example, to use mixed modalities with all local files:
```bash
python openai_chat_completion_client_for_multimodal_generation.py \
--query-type mixed_modalities \
--video-path /path/to/your/video.mp4 \

## Run Local Web UI Demo
This Web UI demo allows users to interact with the model through a web browser.
### Running Gradio Demo
Once vllm and vllm-omni are installed, you can launch the web service built on AsyncOmni by
```bash
python gradio_demo.py --model Qwen/Qwen2.5-Omni-7B --port 7861
```
Then open `http://localhost:7861/` on your local browser to interact with the web UI.
The gradio script supports the following arguments:
- `--model`: Model name
- `--ip`: Host/IP for Gradio server (default: 127.0.0.1)
- `--port`: Port for Gradio server (default: 7861)
- `--stage-configs-path`: Path to custom stage configs YAML file (optional)
- `--share`: Share the Gradio demo publicly (creates a public link)
### FAQ
If you encounter error about backend of librosa, try to install ffmpeg with command below.
```
sudo apt update
sudo apt install ffmpeg
```

# Online serving Example of vLLM-Omni for Qwen3-omni
## 🛠️ Installation
Please refer to [README.md](../../../README.md)
## Run examples (Qwen3-Omni)
### Launch the Server
```bash
vllm serve Qwen/Qwen3-Omni-30B-A3B-Instruct --omni --port 8091
```
If you have custom stage configs file, launch the server with command below
```bash
vllm serve Qwen/Qwen3-Omni-30B-A3B-Instruct --omni --port 8091 --stage-configs-path /path/to/stage_configs_file
```
### Send Multi-modal Request
Get into the example folder
```bash
cd examples/online_serving/qwen3_omni
```
#### Send request via python
```bash
python openai_chat_completion_client_for_multimodal_generation.py --query-type use_image
```
The Python client supports the following command-line arguments:
- `--query-type` (or `-q`): Query type (default: `use_video`)
- Options: `text`, `use_audio`, `use_image`, `use_video`
- `--model` (or `-m`): Model name/path (default: `Qwen/Qwen3-Omni-30B-A3B-Instruct`)
- `--video-path` (or `-v`): Path to local video file or URL
- If not provided and query-type is `use_video`, uses default video URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Example: `--video-path /path/to/video.mp4` or `--video-path https://example.com/video.mp4`
- `--image-path` (or `-i`): Path to local image file or URL
- If not provided and query-type is `use_image`, uses default image URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Supports common image formats: JPEG, PNG, GIF, WebP
- Example: `--image-path /path/to/image.jpg` or `--image-path https://example.com/image.png`
- `--audio-path` (or `-a`): Path to local audio file or URL
- If not provided and query-type is `use_audio`, uses default audio URL
- Supports local file paths (automatically encoded to base64) or HTTP/HTTPS URLs
- Supports common audio formats: MP3, WAV, OGG, FLAC, M4A
- Example: `--audio-path /path/to/audio.wav` or `--audio-path https://example.com/audio.mp3`
- `--prompt` (or `-p`): Custom text prompt/question
- If not provided, uses default prompt for the selected query type
- Example: `--prompt "What are the main activities shown in this video?"`
For example, to use a local video file with custom prompt:
```bash
python openai_chat_completion_client_for_multimodal_generation.py \
--query-type use_video \
--video-path /path/to/your/video.mp4 \
--prompt "What are the main activities shown in this video?"
```
#### Send request via curl
```bash
bash run_curl_multimodal_generation.sh use_image
```
### FAQ
If you encounter error about backend of librosa, try to install ffmpeg with command below.
```
sudo apt update
sudo apt install ffmpeg
```
## Run Local Web UI Demo
This Web UI demo allows users to interact with the model through a web browser.
### Running Gradio Demo
