+## Oracle Cloud Infrastructure (OCI) Generative AI
+
+[Oracle Cloud Infrastructure (OCI)](https://www.oracle.com/cloud/) Generative AI s a fully managed OCI service that provides a set of state-of-the-art, customizable large language models.
+K8sgpt can be configured to use ready-to-use pretrained models, or create and host your own fine-tuned custom models based on your own data on dedicated AI clusters.
+
+To authenticate with OCI, create a [OCI SDK/CLI](https://docs.oracle.com/en-us/iaas/Content/API/Concepts/sdkconfig.htm) `config` file in your home directory's `.oci/` directory.
+
+Next, configure the OCI backend for a given model within an OCI compartment:
+```bash
+k8sgpt auth add --backend oci --model <Model OCID> --compartmentId <Compartment OCID>
+```
+
+Analyze using the OCI backend:
+```bash
+k8sgpt anaylze --explain --backend oci
+```

 ## FakeAI
 
 FakeAI or the NoOpAiProvider might be useful in situations where you need to test a new feature or simulate the behaviour of an AI based-system without actually invoking it. It can help you with local development, testing and troubleshooting.
