FLUX.2 Klein LoRA	`falai/flux-2-klein-lora`	Fastest	Good	Fast iteration, 4B/9B sizes
FLUX Dev (Pruna)	`pruna/flux-dev`	Fast	High	Optimized, speed modes
FLUX Dev LoRA (Pruna)	`pruna/flux-dev-lora`	Fast	High	LoRA with optimization
FLUX Klein 4B (Pruna)	`pruna/flux-klein-4b`	Fastest	Good	Ultra-cheap ($0.0001/img)

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 lora_url 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_url": "https://your-image.jpg"
}'

For Other Image Tasks

# Image editing with natural language
belt app run falai/reve --input '{"prompt": "change background to beach"}'
