+# Yolov8n_pose quantized
+
+## **Use case** : `Pose estimation`
+
+# Model description
+
+Yolov8n_pose is a lightweight and efficient model designed for multi pose estimation tasks. It is part of the YOLO (You Only Look Once) family of models, known for their real-time object detection capabilities. The "n" in Yolov8n_pose indicates that it is a nano version, optimized for speed and resource efficiency, making it suitable for deployment on devices with limited computational power, such as mobile devices and embedded systems.
+
+Yolov8n_pose is implemented in Pytorch by Ultralytics and is quantized in int8 format using tensorflow lite converter.
