Training & fine-tuning

Fastest route: train in Platform

Use Platform cloud training when you want to start in a few clicks without configuring a local GPU:

1. Click New Model on a project page, or on a dataset page to preselect that dataset.
2. Select a compatible pretrained model, ready dataset, GPU, epochs, image size, and batch size.
3. Click Start Training and watch live charts, console logs, and system metrics.
4. Open the completed model to inspect validation plots and use its Predict, Export, or Deploy tab. Platform preserves best.pt automatically.

Cloud jobs require at least one train image, one val/test image, and one labeled image. Use local/Colab training when you already have compute or need more control, while keeping Platform datasets and experiment tracking:

export ULTRALYTICS_API_KEY="YOUR_API_KEY"
yolo train model=yolo26n.pt data=ul://username/datasets/dataset-slug \
  epochs=100 project=username/project-slug name=experiment-1
