+# Ultralytics Docs: Using YOLOv8 with SAHI for Sliced Inference
+
+Welcome to the Ultralytics documentation on how to use YOLOv8 with SAHI (Slicing Aided Hyper Inference). In this comprehensive guide, we'll discuss what SAHI is, the benefits of sliced inference, and how to use SAHI with YOLOv8 for object detection tasks.

+
+## Introduction to SAHI
+
+SAHI is a powerful library aimed at performing efficient and accurate object detection over slices of an image, particularly useful for large scale and high-resolution imagery. It integrates seamlessly with YOLO models and allows for a more efficient usage of computational resources.
+
+## What is Sliced Inference?
+
+Sliced Inference is a technique that divides a large image into smaller slices, performs object detection on each slice, and then aggregates the results back onto the original image. This method is especially beneficial when dealing with high-resolution images as it significantly reduces the computational load without sacrificing detection accuracy.
+
+## Installation and Preparation
+
+### Installation
+
+To get started, install the latest versions of SAHI and Ultralytics:
+
+```bash
+pip install -U ultralytics sahi
+```
+
+### Import Modules and Download Resources
+
+Here's how to import the necessary modules and download a YOLOv8 model and some test images:
+
+```python
+from sahi.utils.yolov8 import download_yolov8s_model
+from sahi import AutoDetectionModel
+from sahi.utils.cv import read_image
+from sahi.utils.file import download_from_url
+from sahi.predict import get_prediction, get_sliced_prediction, predict
+from pathlib import Path
+from IPython.display import Image
+
+# Download YOLOv8 model
+yolov8_model_path = "models/yolov8s.pt"
+download_yolov8s_model(yolov8_model_path)
+
+# Download test images
+download_from_url('https://raw.githubusercontent.com/obss/sahi/main/demo/demo_data/small-vehicles1.jpeg', 'demo_data/small-vehicles1.jpeg')
+download_from_url('https://raw.githubusercontent.com/obss/sahi/main/demo/demo_data/terrain2.png', 'demo_data/terrain2.png')
+```
+
+## Standard Inference with YOLOv8
+
+### Instantiate the Model
+
+You can instantiate a YOLOv8 model for object detection like this:
+
+```python
+detection_model = AutoDetectionModel.from_pretrained(
+    model_type='yolov8',
+    model_path=yolov8_model_path,
+    confidence_threshold=0.3,
+    device="cpu",  # or 'cuda:0'
+)
+```
+
+### Perform Standard Prediction
+
+Perform standard inference using an image path or a numpy image.
+
+```python
+# With an image path
+result = get_prediction("demo_data/small-vehicles1.jpeg", detection_model)
+
+# With a numpy image
+result = get_prediction(read_image("demo_data/small-vehicles1.jpeg"), detection_model)
+```
+
+### Visualize Results
+
+Export and visualize the predicted bounding boxes and masks:
+
+```python
+result.export_visuals(export_dir="demo_data/")
+Image("demo_data/prediction_visual.png")
+```
+
+## Sliced Inference with YOLOv8
+
+Perform sliced inference by specifying the slice dimensions and overlap ratios:
+
+```python
+result = get_sliced_prediction(
+    "demo_data/small-vehicles1.jpeg",
+    detection_model,
+    slice_height=256,
+    slice_width=256,
+    overlap_height_ratio=0.2,
+    overlap_width_ratio=0.2
+)
+```
+
+## Handling Prediction Results
+
+SAHI provides a `PredictionResult` object, which can be converted into various annotation formats:
+
+```python
+# Access the object prediction list
+object_prediction_list = result.object_prediction_list
+
+# Convert to COCO annotation, COCO prediction, imantics, and fiftyone formats
+result.to_coco_annotations()[:3]
+result.to_coco_predictions(image_id=1)[:3]
+result.to_imantics_annotations()[:3]
+result.to_fiftyone_detections()[:3]
+```
+
+## Batch Prediction
+
+For batch prediction on a directory of images:
+
+```python
+predict(
+    model_type="yolov8",
+    model_path="path/to/yolov8n.pt",
+    model_device="cpu",  # or 'cuda:0'
+    model_confidence_threshold=0.4,
+    source="path/to/dir",
+    slice_height=256,
+    slice_width=256,
+    overlap_height_ratio=0.2,
+    overlap_width_ratio=0.2,
+)
+```
+
+That's it! Now you're equipped to use YOLOv8 with SAHI for both standard and sliced inference.
