Creating a Dedicated AI Cluster in Generative AI for Hosting Models

Create a dedicated AI cluster resource in OCI Generative AI to host endpoints for pretrained base models and custom models.

Important

  • Not Available on-demand: All OCI Generative AI foundational pretrained models supported for the on-demand serving mode that use the text generation and summarization APIs (including the playground) are now retired. We recommend that you use the chat models instead.
  • Can be hosted on clusters: If you host a summarization or a generation model such as cohere.command on a dedicated AI cluster, (dedicated serving mode), you can continue to use that model until it's retired. These models, when hosted on a dedicated AI cluster are only available in US Midwest (Chicago). See Retiring the Models for retirement dates and definitions.
  1. In the navigation bar of the Console, select a region with Generative AI, for example, US Midwest (Chicago) or UK South (London). See which models are offered in your region.
  2. Open the navigation menu  and select Analytics & AI. Under AI Services, select Generative AI.
  3. Select a compartment in which you want to host the models.
    Ensure that you have permission to use or manage generative-ai-family and object-family resources in this compartment.
  4. In the left navigation, select a compartment that you have permission to work in.
  5. Click Dedicated AI clusters.
  6. Click Create dedicated AI cluster.
  7. Select a compartment to create the dedicated AI cluster in. The default compartment is the one you selected in step 3, but you can select any compartment that you have permission to work in.
  8. (Optional) Enter a name and description for the cluster. If you don't enter a name, the system generates one that you can change later.

    The generated name has the format generativeaidedicatedaicluster<timestamp>. For example: generativeaidedicatedaicluster20240601202357

  9. For Cluster type, click Hosting.
  10. For Base model, select the foundational base model for the models that you want to host on this cluster. The model list includes only the base models that are not yet retired for the on-demand mode.
    For dedicated cluster unit sizes, see Matching Base Models to Clusters For rules about creating endpoints for the models hosted on clusters, see Adding Endpoints to Hosting Clusters.
  11. (Optional) Increase the number of instances in the Model replica field.
    Important

    When you create a cluster for hosting models for inference, by default one unit is created for the base model that you select. To increase the throughput, you can increase the number of instances in the Model replica field now, or later when you edit the cluster. For example, creating two model replicas on this cluster, requires two units.
  12. Read the commitment unit hours for the hosting cluster and select the checkbox to agree to the commitment.
  13. (Optional) Click Show advanced options and assign tags to this cluster.
  14. Click Create.
    Note

    Clusters take a few minutes to create. After the cluster is in an active state, you can select that cluster to host a model, when you create an endpoint for that model.
