Examples
High-Quality Generation
belt app run falai/flux-dev-lora --input '{
"prompt": "professional product photo of headphones, studio lighting, white background"
}'
Fast Generation (Klein)
belt app run falai/flux-2-klein-lora --input '{"prompt": "abstract art, colorful"}'
With LoRA Custom Styles
belt app sample falai/flux-dev-lora --save input.json
# Edit to add "loras": [{"path": "<lora-url>", "scale": 1.0}] for custom style
belt app run falai/flux-dev-lora --input input.json
Image-to-Image
belt app run falai/flux-dev-lora --input '{
"prompt": "transform to watercolor style",
"image": "https://your-image.jpg"
}'
For Other Image Tasks
# Image editing with natural language
belt app run falai/reve --input '{"prompt": "change background to beach"}'
# Upscaling
belt app run falai/topaz-image-upscaler --input '{"image": "https://..."}'
