How to Use Qwen-Image LoRA Trainer API

Prepare your dataset: Create a .zip archive containing high-quality training images along with optional .txt caption files.
Set training parameters: Customize trigger_word, steps (default 1000), learning_rate (default 0.0004), and lora_rank (default 16).
Submit prediction via API:

curl -X POST "https://api.muapi.ai/api/v1/qwen-image-lora-trainer" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "data": "https://example.com/my-qwen-dataset.zip",
    "trigger_word": "qwen_character",
    "steps": 1000,
    "learning_rate": 0.0004,
    "lora_rank": 16
  }'
