yolov8 — What's That AI

<br>

Ultralytics YOLOv8 is available
through the official Ultralytics YOLO package. It supports object
detection, instance segmentation, image classification, pose estimation, and tracking in a fast, accurate, and easy to
use Python and CLI workflow.

This repository is a lightweight discovery page for YOLOv8. The canonical implementation, package releases, model
downloads, issues, and pull requests are maintained in ultralytics/ultralytics.

Python

from ultralytics import YOLO

# Load a pretrained YOLOv8n model
model = YOLO("yolov8n.pt")

# Run inference on the sample image
results = model("https://ultralytics.com/images/bus.jpg")

# Display the annotated results
results[0].show()
