The job then runs on the platform's GPU cluster. When training completes: * **LoRA jobs**: Create an **Adapter** attached to the original Model Entity. Adapters can be auto-deployed to NIMs. * **Full fine-tuning jobs**: Create a **new Model Entity** with the customized weights, linked to the base model. This design keeps adapters organized with their parent models and simplifies deployment workflows. Submission is backend-specific (you submit to the automodel or unsloth backend), but every job runs on the shared platform **Jobs** service. As a result, you poll status, list, and cancel jobs through that service the same way regardless of which backend you used. ## Prerequisites Before you can customize a model using a customization job, make sure that you have [prepared and uploaded a dataset](/documentation/customizer-reference/tutorials/format-training-dataset) to the dataset repository. *** ## Task Guides Perform common customization job tasks. The value for `NMP_BASE_URL` will depend on your deployment. After the standard [Setup](/documentation/get-started) flow, the default local URL is `http://localhost:8080`. Otherwise, consult with your cluster administrator. Create a customization job using SFT or Knowledge Distillation. Check the status of a customization job. List all active customization jobs to find a job name for use with Get Status or Cancel. Cancel a customization job using its name and workspace. ## References Refer to the following pages for more information on customization jobs.
