Reasons for Recommendation

New model; serves text-to-image needs requiring transparent backgrounds, such as stickers, icons, and e-commerce white-background assets, saving the step of using rembg / BiRefNet for cutouts
Actionable: Strength 0.95–1.00, 8 steps (4–8 steps also acceptable), CFG 1.0, include trigger words in the prompt
License allows commercial use of generated images and publication of derivative models; 6 visible examples

How to Use

Load flux3_klein_transparent_lora.safetensors, write 'RGBA transparent background, isolated foreground object' in the prompt; the VAE must be replaced with the author-specified 4-channel RGBA VAE, and an RGBA decoding node must be used

Risks and Limitations

Standard VAEs only decode RGB; failing to replace the VAE and decoding node will result in no transparent channel
The base model is labeled as Flux.2 Klein 9B, while the description states FLUX 3 Image Klein; 4 examples are hidden due to rating; this entry has not been tested

Trigger Words: RGBA transparent background, isolated foreground object, transparent background
