Train custom LoRA models on fal.ai for personalized AI generation.

Scripts

Script	Purpose
`train.sh`	Submit a LoRA training job

Usage

Train Image LoRA (Style/Subject/Person)

./scripts/train.sh --images-url "https://example.com/training-images.zip" --trigger-word "sks style" --model fal-ai/flux-lora-fast-training

Train Portrait LoRA

./scripts/train.sh --images-url "https://example.com/face-photos.zip" --trigger-word "ohwx person" --model fal-ai/flux-lora-portrait-trainer

Check Training Status

./scripts/train.sh --status --endpoint fal-ai/flux-lora-fast-training --request-id "abc123"

Arguments

Argument	Description	Required
`--images-url`	URL to zip of training images	Yes
`--trigger-word`	Word to activate the LoRA in prompts	Yes
`--model` / `-m`	Training model endpoint	No (default: fal-ai/flux-lora-fast-training)
`--steps`	Training steps	No (default: 1000)
`--status`	Check training job status	No
`--endpoint`	Endpoint for status check	With --status
`--request-id`	Request ID for status check	With --status
`--param`	Extra param as key=value (repeatable)	No

Finding Models

To discover the best and latest training/LoRA models, use the search API:

# Search for LoRA training models
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "lora training"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "trainer"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "fine-tune"

Or use the search_models MCP tool with keywords like "lora", "training", "trainer", "fine-tune".

Training Data Tips

People: 10-20 photos, varied angles/lighting/expressions, consistent person
Styles: 10-15 images exemplifying the style, diverse subjects
Objects: 5-15 photos from different angles on various backgrounds
Images should be high quality, at least 512x512
Zip all images into a single .zip file and host at a URL

Output Format

{
  "diffusers_lora_file": {
    "url": "https://fal.media/files/.../lora.safetensors",
    "content_type": "application/octet-stream",
    "file_name": "lora.safetensors",
    "file_size": 12345678
  },
  "config_file": {
    "url": "https://fal.media/files/.../config.json"
  }
}

Use the diffusers_lora_file.url as the lora_url parameter when generating images with FLUX models.
