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.
