Choosing an Ultralytics model

Default recommendation: YOLO26, pretrained. Latest generation, with an optional NMS-free head (nms=False) for the fastest CPU inference and simplest deployment. Use YOLO11/YOLOv8 only to match an existing codebase or a deployment target that doesn't support YOLO26 yet. Most official weights auto-download on first use; sam3.pt and sam3.1_multiplex.pt require manual access and download.

Choose in Platform

For the quickest no-code start, click New Model in a project. Its Official tab lists YOLO26 (recommended), YOLO11, YOLOv8, and YOLOv5 models whose task can train the selected dataset; My Models lists your completed or uploaded checkpoints for further fine-tuning. To browse the official models first, open the @ultralytics projects under Projects in Platform Explore.

Use a Platform model page to inspect metrics, test it in Predict, export it, deploy it, clone a public model into your workspace, or download its .pt weights for the Python/CLI workflows below. See Platform Models and Explore.
