Ultralytics HUB Models

Ultralytics HUB models provide a streamlined solution for training vision AI models on custom datasets.

The process is user-friendly and efficient, involving a simple three-step creation and accelerated training powered by Ultralytics YOLOv8. During training, real-time updates on model metrics are available so that you can monitor each step of the progress. Once training is completed, you can preview your model and easily deploy it to real-world applications. Therefore, Ultralytics HUB offers a comprehensive yet straightforward system for model creation, training, evaluation, and deployment.


Watch: Ultralytics HUB Training and Validation Overview

Train Model

Navigate to the Models page by clicking on the Models button in the sidebar and click on the Train Model button on the top right of the page.

??? tip "Tip"

You can train a model directly from the [Home](https://hub.ultralytics.com/home) page.

![Ultralytics HUB screenshot of the Home page with an arrow pointing to the Train Model card](https://raw.githubusercontent.com/ultralytics/assets/main/docs/hub/models/hub_train_model_1.jpg)

This action will trigger the Train Model dialog which has three simple steps:

1. Dataset

In this step, you have to select the dataset you want to train your model on. After you selected a dataset, click Continue.

??? tip "Tip"

You can skip this step if you train a model directly from the Dataset page.

![Ultralytics HUB screenshot of the Dataset page with an arrow pointing to the Train Model button](https://raw.githubusercontent.com/ultralytics/assets/main/docs/hub/datasets/hub_upload_dataset_9.jpg)

2. Model

In this step, you have to choose the project in which you want to create your model, the name of your model and your model's architecture.

Ultralytics HUB screenshot of the Train Model dialog with arrows pointing to the project dropdown, model name and Continue button

??? note "Note"

Ultralytics HUB will try to pre-select the project.

If you opened the **Train Model** dialog as described above, [Ultralytics HUB](https://ultralytics.com/hub) will pre-select the last project you used.

If you opened the **Train Model** dialog from the Project page, [Ultralytics HUB](https://ultralytics.com/hub) will pre-select the project you were inside of.

![Ultralytics HUB screenshot of the Project page with an arrow pointing to the Train Model button](https://raw.githubusercontent.com/ultralytics/assets/main/docs/hub/projects/hub_create_project_5.jpg)

In case you don't have a project created yet, you can set the name of your project in this step and it will be created together with your model.

!!! Info "Info"

You can read more about the available [YOLOv8](https://docs.ultralytics.com/models/yolov8) (and [YOLOv5](https://docs.ultralytics.com/models/yolov5)) architectures in our documentation.

By default, your model will use a pre-trained model (trained on the COCO dataset) to reduce training time. You can change this behavior and tweak your model's configuration by opening the Advanced Model Configuration accordion.

Ultralytics HUB screenshot of the Train Model dialog with an arrow pointing to the Advanced Model Configuration accordion

!!! note "Note"

You can easily change the most common model configuration options (such as the number of epochs) but you can also use the **Custom** option to access all [Train Settings](https://docs.ultralytics.com/modes/train/#train-settings) relevant to [Ultralytics HUB](https://ultralytics.com/hub).



Watch: How to Configure Ultralytics YOLOv8 Training Parameters in Ultralytics HUB

Alternatively, you start training from one of your previously trained models by clicking on the Custom tab.

When you're happy with your model configuration, click Continue.

3. Train

In this step, you will start training you model.

??? note "Note"

When you are on this step, you have the option to close the **Train Model** dialog and start training your model from the Model page later.
