In the Open Data Hub project (ODH) KServe is provided, however not all KServe features are currently supported, because OpenShift integration is not complete yet.
The previous doesn't mean that OpenShift is not compatible with KServe (or vice-versa). You should be able to use KServe in OpenShift by following upstream instructions: https://kserve.github.io/website/latest/get_started/, but you will require to install the whole stack by yourself. In ODH one of the goals is to provide a AI platform that is well integrated with OpenShift and providing a package that is easy to install. For KServe, such integration is not finished yet.
