# Models |
|
|
|
Ultralytics supports many models and architectures with more to come in the future. Want to add your model architecture? [Here's](../help/contributing.md) how you can contribute. |
|
|
|
In this documentation, we provide information on four major models: |
|
|
|
1. [YOLOv3](./yolov3.md): The third iteration of the YOLO model family originally by Joseph Redmon, known for its efficient real-time object detection capabilities. |
|
2. [YOLOv4](./yolov3.md): A darknet-native update to YOLOv3 released by Alexey Bochkovskiy in 2020. |
|
3. [YOLOv5](./yolov5.md): An improved version of the YOLO architecture by Ultralytics, offering better performance and speed tradeoffs compared to previous versions. |
|
4. [YOLOv6](./yolov6.md): Released by [Meituan](https://about.meituan.com/) in 2022 and is in use in many of the company's autonomous delivery robots. |
|
5. [YOLOv7](./yolov7.md): Updated YOLO models released in 2022 by the authors of YOLOv4. |
|
6. [YOLOv8](./yolov8.md): The latest version of the YOLO family, featuring enhanced capabilities such as instance segmentation, pose/keypoints estimation, and classification. |
|
7. [Segment Anything Model (SAM)](./sam.md): Meta's Segment Anything Model (SAM). |
|
8. [YOLO-NAS](./yolo-nas.md): YOLO Neural Architecture Search (NAS) Models. |
|
9. [Realtime Detection Transformers (RT-DETR)](./rtdetr.md): Baidu's PaddlePaddle Realtime Detection Transformer (RT-DETR) models. |
|
|
|
You can use these models directly in the Command Line Interface (CLI) or in a Python environment. Below are examples of how to use the models with CLI and Python: |
|
|
|
## CLI Example |
|
|
|
```bash |
|
yolo task=detect mode=train model=yolov8n.yaml data=coco128.yaml epochs=100 |
|
``` |
|
|
|
## Python Example |
|
|
|
```python |
|
from ultralytics import YOLO |
|
|
|
model = YOLO("model.yaml") # build a YOLOv8n model from scratch |
|
# YOLO("model.pt") use pre-trained model if available |
|
model.info() # display model information |
|
model.train(data="coco128.yaml", epochs=100) # train the model |
|
``` |
|
|
