Model Selection Guide

General Editing (Recommended)

Nano Banana Pro (

fal-ai/nano-banana-pro

)

Best overall for image editing and T2I
High quality, versatile
Good for most editing tasks

Style Transfer

FLUX Image-to-Image (

fal-ai/flux/dev/image-to-image

)

Best for: Artistic style changes
Strength: 0.3-0.5 for subtle, 0.7-0.9 for dramatic

Object Removal

Bria Fibo Edit (

fal-ai/bria/fibo-edit

)

Best for: Removing objects, people, text
Works without masks (AI detects objects from prompt)

Background Change

FLUX Kontext (

fal-ai/flux-kontext

)

Best for: Placing subjects in new environments
Preserves subject identity well

Inpainting

FLUX Inpainting (

fal-ai/flux/dev/inpainting

)

Best for: Precise edits with mask control
Requires binary mask (white = edit area)

Mask Tips

For inpainting and some removal tasks:

White pixels = areas to edit
Black pixels = areas to preserve
Use PNG format with transparency or solid colors
Feathered edges create smoother transitions

Troubleshooting

Edit Too Subtle

The edit is barely visible.

Increase the strength parameter:
--strength 0.85

Edit Too Dramatic

The edit changed too much of the image.

Decrease the strength parameter:
--strength 0.3

Object Not Removed

The object wasn't fully removed.

Tips:
1. Be more specific in the prompt
2. Try using an explicit mask
3. Use the inpainting model for precise control

Background Artifacts

The new background has artifacts around the subject.

Tips:
1. Use a cleaner source image
2. Try FLUX Kontext which handles edges better
3. Adjust the strength for smoother blending
