# Manage Customization Jobs

Use customization jobs to fine-tune a [model](/documentation/customizer-reference/models/model-catalog) using a [dataset](/documentation/get-started/core-concepts/manage-files) and [hyperparameters](/documentation/customizer-reference/manage-customization-jobs/training-configuration).

## How It Works

A customization job references a **Model Entity** that contains the base model checkpoint, and is submitted to one of two backends — **automodel** (default, multi-GPU) or **unsloth** (single-GPU, with optional quantized loading for LoRA). 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.

> **Tip**
>
> The value for `NHX_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.
