Platform CLI (ul cloud)

ul needs Python 3.11+ and comes with pip install ultralytics or pip install ultralytics-platform. ul cloud <resource> <operation> calls the Platform API through the generated SDK; ul login, ul train, ul predict, the ul cloud train|predict|export|download shortcuts (see yolo), and the other local commands delegate to the ultralytics package. This skill covers Platform operations, not model selection or hyperparameter tuning.

pip install ultralytics                   # or `pip install ultralytics-platform`
export ULTRALYTICS_API_KEY="YOUR_API_KEY" # or `ul login API_KEY`
ul cloud --help                           # every resource and operation
ul cloud training start --help            # one operation's arguments, types, and choices
