yolo-models SKILL.md skillA
yolo-models from ultralytics/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ultralytics/skills/yolo-models@git:20261101.a2f590fPins git:20261101.a2f590f in mdr.lock. Pin the fingerprint instead.

Use when choosing or comparing Ultralytics models in Platform or code — picking a model family (YOLO26/YOLO11/YOLOv8, YOLO-World, YOLOE, SAM/SAM2/FastSAM, RT-DETR, YOLO-NAS), size (n/s/m/l/x), task variant (-seg, -sem, -cls, -pose, -obb, -depth), pretrained checkpoint, open-vocabulary or promptable detection/segmentation, custom architecture, Platform Explore, or exact weight names and availability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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](https://platform.ultralytics.com/explore). …

How to install
mdr add ultralytics/skills/yolo-models@sha256:b6469fb12c321320The line at the top of this page pins the label git:20261101.a2f590f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
