Chapter 1. About model serving
Serving trained models on Red Hat OpenShift AI means deploying the models on your OpenShift cluster to test and then integrate them into intelligent applications. Deploying a model makes it available as a service that you can access by using an API. This enables you to return predictions based on data inputs that you provide through API calls. This process is known as model inferencing. When you serve a model on OpenShift AI, the inference endpoints that you can access for the deployed model are shown in the dashboard.
OpenShift AI provides the following model serving platforms:
- Single-model serving platform
- For deploying large models such as large language models (LLMs), OpenShift AI includes a single-model serving platform that is based on the KServe component. Because each model is deployed from its own model server, the single-model serving platform helps you to deploy, monitor, scale, and maintain large models that require increased resources.
- Multi-model serving platform
- For deploying small and medium-sized models, OpenShift AI includes a multi-model serving platform that is based on the ModelMesh component. On the multi-model serving platform, you can deploy multiple models on the same model server. Each of the deployed models shares the server resources. This approach can be advantageous on OpenShift clusters that have finite compute resources or pods.
