 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.

-        if not 0 < self.max_gpu_utilization <= 1:
-            raise ValueError("max_gpu_utilization must be between 0 and 1")
-```
-
-### 5. Error Handling
-
-```python
-class CoreModuleError(Exception):
-    """Base exception for core module errors."""
-    pass
-
-class SchedulerError(CoreModuleError):

-    """Queue is at capacity."""
-    pass
-
-class CacheError(CoreModuleError):
-    """Cache-related errors."""
-    pass
-
-class ResourceError(CoreModuleError):
-    """Resource allocation errors."""
-    pass
-```
-
-### 6. Examples
-
-#### Basic Usage
-```python
-from vllm_omni.core import CoreScheduler, CoreModuleConfig
-from vllm_omni.request import create_text_request
-
-# Create configuration
-config = CoreModuleConfig(
-    scheduler=SchedulerConfig(scheduler_type=SchedulerType.FIFO),
-    max_memory_gb=8.0
-)
-
-# Initialize scheduler
-scheduler = CoreScheduler(config)
-await scheduler.start()
-
-# Create and schedule a request
-request = create_text_request(
-    request_id="req_001",
-    prompt="Hello, world!",
-    sampling_params=sampling_params
-)
-
-success = await scheduler.schedule_request(request)
-if success:
-    result = await scheduler.process_request(request)
-    print(f"Result: {result}")
-```
-
-#### Advanced Usage
-```python
-# Custom scheduler with priority handling
-config = CoreModuleConfig(
-    scheduler=SchedulerConfig(
-        scheduler_type=SchedulerType.PRIORITY,
-        priority_weights={"high": 2.0, "normal": 1.0, "low": 0.5}
-    )
-)
-
-scheduler = CoreScheduler(config)
-await scheduler.start()
-
-# Monitor scheduler status
-status = scheduler.get_status()
-print(f"Queue size: {status['queue_size']}")
-print(f"Cache hit rate: {status['cache_hit_rate']:.2%}")
-```

 > 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: 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 none 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!

+# 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.

+#### 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

-```bash
-python gradio_demo.py \

+The gradio script supports the following arguments:

 - `--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)
