You can create a custom model by using your dataset to fine-tune an out-of-the-box text generation base model. Have your dataset ready before you create a custom model. See Training Data Requirements.

To use any of the API operations, you must be authorized in an IAM policy. If you’re not authorized, talk to an administrator who gives OCI resource access to users. See Getting Started with Policies and Getting Access to Generative AI Resouces.
