How to Train a Custom YOLO Model for Your Game

March 2026 9 min read

Custom YOLO models trained on specific games outperform general models significantly. Here's how to train your own.

Step 1: Collect Screenshots

Play your target game and capture 200-500 screenshots with enemies visible. Use different maps, lighting conditions, and character skins. The more variety, the better.

Step 2: Label Your Data

Use a tool like LabelImg or Roboflow to draw bounding boxes around enemy players in each screenshot. Label them as "player" or "enemy." This creates the training annotations.

Step 3: Train the Model

Use Ultralytics YOLOv8 or v11. Training on 300 images takes about 30-60 minutes on a modern GPU. Use Nano size for maximum inference speed.

Step 4: Export to ONNX

Export your trained model to .onnx format. Skyrant loads any .onnx file directly — it auto-detects resolution, classes, format, and precision.

Step 5: Load in Skyrant

Upload your .onnx file through the Skyrant dashboard. The client downloads it automatically and starts using it for detection. No configuration needed.

Load Any Custom Model

Train it. Export to ONNX. Skyrant does the rest.
