# Models Supported by Ultralytics

Welcome to Ultralytics' model documentation! We offer support for a wide range of models, each tailored to specific tasks like [object detection](../tasks/detect.md), [instance segmentation](../tasks/segment.md), [image classification](../tasks/classify.md), [pose estimation](../tasks/pose.md), and [multi-object tracking](../modes/track.md). If you're interested in contributing your model architecture to Ultralytics, check out our [Contributing Guide](../help/contributing.md).

## Getting Started: Usage Examples

This example provides simple YOLO training and inference examples. For full documentation on these and other [modes](../modes/index.md) see the [Predict](../modes/predict.md), [Train](../modes/train.md), [Val](../modes/val.md) and [Export](../modes/export.md) docs pages.

Note the below example spotlights YOLO11 [Detect](../tasks/detect.md) models for [object detection](https://www.ultralytics.com/glossary/object-detection). For additional supported tasks see the [Segment](../tasks/segment.md), [Classify](../tasks/classify.md) and [Pose](../tasks/pose.md) docs.

!!! example

    === "Python"

        [PyTorch](https://www.ultralytics.com/glossary/pytorch) pretrained `*.pt` models as well as configuration `*.yaml` files can be passed to the `YOLO()`, `SAM()`, `NAS()` and `RTDETR()` classes to create a model instance in Python:

        ```python
        from ultralytics import YOLO

        # Load a COCO-pretrained YOLO26n model
        model = YOLO("yolo26n.pt")

        # Display model information (optional)
        model.info()

        # Train the model on the COCO8 example dataset for 100 epochs
        results = model.train(data="coco8.yaml", epochs=100, imgsz=640)

        # Run inference with the YOLO26n model on the 'bus.jpg' image
        results = model("path/to/bus.jpg")
        ```

    === "CLI"

        CLI commands are available to directly run the models:

        ```bash
        # Load a COCO-pretrained YOLO26n model and train it on the COCO8 example dataset for 100 epochs
        yolo train model=yolo26n.pt data=coco8.yaml epochs=100 imgsz=640

        # Load a COCO-pretrained YOLO26n model and run inference on the 'bus.jpg' image
        yolo predict model=yolo26n.pt source=path/to/bus.jpg
        ```

        from ultralytics import YOLO

        # Load a YOLO model
        model = YOLO("yolo26n.pt")  # or any other YOLO model

        # Train the model on custom dataset
        results = model.train(data="custom_data.yaml", epochs=100, imgsz=640)
        ```

    === "CLI"

        ```bash
        yolo train model=yolo26n.pt data='custom_data.yaml' epochs=100 imgsz=640
        ```

For more detailed instructions, visit the [Train](../modes/train.md) documentation page.

### Why should I use Ultralytics Platform for [machine learning](https://www.ultralytics.com/glossary/machine-learning-ml) projects?

[Ultralytics Platform](../platform/index.md) provides a no-code, end-to-end platform for training, deploying, and managing YOLO models. It simplifies complex workflows, enabling users to focus on model performance and application. The HUB also offers [cloud training capabilities](../platform/train/cloud-training.md), comprehensive dataset management, and user-friendly interfaces for both beginners and experienced developers.

### What types of tasks can Ultralytics YOLO models perform?

Ultralytics YOLO models are versatile and can perform tasks including object detection, instance segmentation, classification, pose estimation, and oriented object detection (OBB). The latest model, [YOLO26](yolo26.md), supports all five tasks plus open-vocabulary detection. For details on specific tasks, refer to the [Task pages](../tasks/index.md).
