Generative AI Regions
Learn where OCI Generative AI hosts models and how to access the service from CPU-only regions.
Oracle hosts its OCI services in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers in that region.
See Generative AI Models by Region for model availability in the regions that serve inference requests. For regions with CPU-only access to on-demand inference, see Commercial Regions (OC1) with CPU-Only Access.
Commercial Regions (OC1) with Model Hosting
The following table lists the OC1 regions where Generative AI hosts models. Available models and serving modes vary by region. To use an on-demand model that isn't available locally, create a routing profile for that model and select regions where it is available. Use the profile from your current region in the Playground or through a supported inference API.

Commercial Regions (OC1) with CPU-Only Access
For the OC1 regions that support CPU-only access to on-demand inference in Generative AI, see Commercial Regions (OC1) with CPU-Only Access. This list includes UAE Central (Abu Dhabi), which also hosts models for dedicated AI clusters. For all OCI commercial regions, see the OCI regions table and refer to entries with the realm key OC1.
In a CPU-only region, create a routing profile for the on-demand model you want to use and select target regions where it is available. Select the profile in your region's Playground or reference it in an API request to run the model in a selected target region. The Chat API, OpenAI-compatible Chat Completions API, and Responses API are supported when the selected model supports the API. Regional API endpoints support IPv6.
For supported features, limitations, and routing instructions, see Generative AI in CPU-Only Regions.

Services that Call into the Generative AI Service
Some OCI services call the Generative AI service. The following table lists the calling and destination regions for those service integrations.
There are OCI services which document (in the “Oracle PaaS and IaaS Universal Credits Service Descriptions”) that they make calls into the OCI Generative AI Service. For a given call into the OCI Generative AI Service, if the Calling Region and Destination Region are not the same, then a cross-region call will be made.
