Review PRs on vllm-project/vllm-omni by routing to the right domain skills, checking critical evidence, and focusing comments on blocking issues. Use when reviewing pull requests or local branches, triaging review depth, running detailed or default review, or checking tests, benchmarks, and breaking changes in vllm-omni.
Two report kinds; **default output is always HTML** unless the user explicitly asks for Markdown (.md). **Release** — `scripts/compose_full_report.py` (**测试结论**, Buildkite metrics, **Test Result** = Common stack + optional `--log-dir-h*` nightly-style summaries + H100/CI block, **Issue tracking** = GitHub `ci-failure` + *local test* in:title, Open bugs); use `--format markdown` only when the user wants .md or `patch_report_*.py`. **Nightly** — `scripts/nightly_local_log_report.py` from local `nightly_jobs` (fetch: vllm-omni-nightly-local) plus optional latest Buildkite scheduled nightly when token is set; use `--markdown-report` / `--to-stdout markdown` only when the user asks for Markdown. Use when generating Buildkite release summaries, parsing local nightly_jobs with CI cross-check, or opening https://buildkite.com/vllm/vllm-omni/builds?branch=main for CI documentation.
Use before submitting a PR to vllm-project/vllm-omni — self-check the branch against project conventions, catch dead code, verify accuracy/performance claims, and confirm merge readiness. Use when the user says "pre-check", "self review", "pre-submit check", or "check my PR before I open it."
Generate audio and speech with vLLM-Omni using Qwen3-TTS, Fish Speech S2 Pro, CosyVoice3, MiMo-Audio, and Stable-Audio models. Use when synthesizing speech from text, generating audio effects or music, configuring TTS parameters, cloning voices, adding new TTS models, or working with text-to-speech models.
Contribute to vLLM-Omni by adding new model support, fixing bugs, or improving features. Use when integrating a new model into vllm-omni, setting up a development environment, writing tests, or submitting pull requests to the vllm-omni project.
Scale vLLM-Omni across multiple GPUs and nodes using tensor parallelism, pipeline parallelism, OmniConnector disaggregation, connector backends, and Ray. Use when setting up multi-GPU inference, distributing model execution across machines, deploying disaggregated execution, developing OmniConnector backends, or scaling inference horizontally.

vLLM-Omni extends vLLM to support omni-modality model inference (text, image, video, audio) with both autoregressive and diffusion architectures. This skill covers installation from source and environment configuration.
Set these before running any commands. Check the vllm-omni quickstart for currently recommended versions.
export VLLM_VERSION="0.20.0" # vLLM pip package version
export VLLM_OMNI_VERSION="v0.20.0" # vLLM-Omni release / Docker tag
export PYTHON_VERSION="3.12" # Python version
uv package manager (recommended) or pipuv venv --python $PYTHON_VERSION --seed
source .venv/bin/activate
Select the command matching your hardware:
NVIDIA GPU (CUDA):
uv pip install vllm==$VLLM_VERSION --torch-backend=auto
ROCm (AMD):
uv pip install vllm==$VLLM_VERSION --extra-index-url https://wheels.vllm.ai/rocm/$VLLM_VERSION/rocm722
git clone https://github.com/vllm-project/vllm-omni.git
cd vllm-omni
uv pip install -e .
from vllm_omni.entrypoints.omni import Omni
print("vLLM-Omni installed successfully")
Run a minimal text-to-image generation to verify the full stack:
from vllm_omni.entrypoints.omni import Omni
omni = Omni(model="Tongyi-MAI/Z-Image-Turbo")
outputs = omni.generate("a red circle on white background")
outputs[0].request_output[0].images[0].save("test.png")
print("Setup verified - test.png generated")
For containerized deployment:
docker pull vllm/vllm-omni:$VLLM_OMNI_VERSION
docker run --gpus all -p 8091:8091 vllm/vllm-omni:$VLLM_OMNI_VERSION \
vllm serve Tongyi-MAI/Z-Image-Turbo --omni --port 8091
| Variable | Purpose | Default |
|---|---|---|
VLLM_OMNI_LOG_LEVEL | Logging verbosity | INFO |
HF_HOME | Hugging Face cache directory | ~/.cache/huggingface |
CUDA_VISIBLE_DEVICES | GPU device selection | all GPUs |
VLLM_WORKER_MULTIPROC_METHOD | Worker process method | spawn |
CUDA version mismatch: Ensure your CUDA toolkit version matches the PyTorch build. Check with nvidia-smi and python -c "import torch; print(torch.version.cuda)".
Out of memory on model load: Use gpu_memory_utilization parameter to limit memory. Start with 0.8 and adjust:
omni = Omni(model="...", gpu_memory_utilization=0.8)
Model download failures: Set HF_HOME to a directory with sufficient disk space. Large models (e.g., Qwen3-Omni-30B) require 60GB+ of disk.
