Hi,
I understand vLLM Omni is totally different thing and it includes vLLM. I havent yet tried Omni.
My question is, how the vLLM is included in the vLLM omni docker images? Is it coming behind in versions? I am trying to figure out can vLLM Omni run the latest LLM models like Gemma4 or do I have to wait that vLLM omni updates its vLLM version in its docker images to support latest LLM models?
vLLM-Omni Docker images are built on top of vLLM Docker images, and the version of vLLM-Omni indicates which vLLM release it is based on. This means the vLLM version inside a vLLM-Omni image is not always the latest upstream vLLM; it matches the version specified by the vLLM-Omni release. To run the latest LLM models (like Gemma4), you need to ensure that the vLLM version bundled in the vLLM-Omni image supports those models—otherwise, you must wait for vLLM-Omni to update its base vLLM version in a new release or build from source with the desired vLLM version yourself. According to the official installation docs and Docker image notes, this is the standard workflow.
If you need the absolute latest model support (e.g., for Gemma4), check the supported models list and the vLLM version in the vLLM-Omni image. If the model is not yet supported in the current vLLM-Omni release, you will need to wait for an update or manually build vLLM-Omni with a newer vLLM base. Would you like more detail on how to build a custom Docker image or check model compatibility?

Yes, if it is safe and straightforward to somehow update the vLLM version inside the vLLM Omni docker image, then you could give me step by step inst. how to update a vLLM Omni image to have the latest vLLM version. I have done dockerfiles and build some simple ones but I guess this might need some more. Is there a risk that if the vLLM is upgraded the the whole Omni wont work?
It is possible to update the vLLM version inside a vLLM-Omni Docker image, but there is a risk: vLLM-Omni and vLLM must be version-matched for compatibility. If you upgrade vLLM beyond what vLLM-Omni expects, Omni may fail to work or behave unpredictably. The vLLM-Omni project enforces a version compatibility check at startup, and mismatches will cause errors unless you override with an environment variable (not recommended for production) (source).
Would you like detailed, step-by-step instructions for building a custom vLLM-Omni Docker image with a specific vLLM version, along with guidance on managing compatibility risks?
