# Model Training

Agent-driven custom model training powered by Aegis's Training Agent. Closes the annotation-to-deployment loop: take a COCO dataset from `dataset-annotation`, fine-tune a YOLO model, auto-export to the optimal format for your hardware, and optionally deploy it as your active detection skill.

## What You Get

- **Fine-tune YOLO26** — start from nano/small/medium/large pre-trained weights
- **COCO dataset input** — uses standard format from `dataset-annotation` skill
- **Hardware-aware training** — auto-detects CUDA, MPS, ROCm, or CPU
- **Auto-export** — converts trained model to TensorRT / CoreML / OpenVINO / ONNX via `env_config.py`
- **One-click deploy** — replace the active detection model with your fine-tuned version
- **Training telemetry** — real-time loss, mAP, and epoch progress streamed to Aegis UI

## Training Loop (Aegis Training Agent)
