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

You can train a model directly from the Home page.

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

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

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.

Note

Ultralytics HUB will try to pre-select the project.

If you opened the Train Model dialog as described above, Ultralytics HUB will pre-select the last project you used.

If you opened the Train Model dialog from the Project page, Ultralytics HUB will pre-select the project you were inside of.

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

You can read more about the available YOLOv8 (and 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.

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 relevant to Ultralytics 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

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.

To train models using our Cloud Training solution, read the Ultralytics Cloud Training documentation.

b. Google Colab

To start training your model using Google Colab, follow the instructions shown in the Ultralytics HUB Train Model dialog or on the Google Colab notebook.

Open In Colab

Analyze Model

After you train a model, you can analyze the model metrics.

The Train tab presents the most important metrics carefully grouped based on the task.

Preview Model

After you train a model, you can preview it by clicking on the Preview tab.

In the Test card, you can select a preview image from the dataset used during training or upload an image from your device.

Share Model

Info

Ultralytics HUB's sharing functionality provides a convenient way to share models with others. This feature is designed to accommodate both existing Ultralytics HUB users and those who have yet to create an account.

Note

You have control over the general access of your models.

You can choose to set the general access to "Private", in which case, only you will have access to it. Alternatively, you can set the general access to "Unlisted" which grants viewing access to anyone who has the direct link to the model, regardless of whether they have an Ultralytics HUB account or not.

Navigate to the Model page of the model you want to share, open the model actions dropdown and click on the Share option. This action will trigger the Share Model dialog.
