Capabilities

Four creative tools, one model

Seed control

Lock the random seed to reproduce any result. Adjust the prompt slightly and the same seed gives you a controlled variation. Essential for iterative refinement and brand-consistent campaigns.

Image to image

Upload any photo and transform style, lighting, color, or subject while preserving composition. Adjust denoising strength to dial in how much changes.

Inpainting

Brush over any region of an image and regenerate just that area. Replace backgrounds, swap products, fix hands, edit text, all without re-rolling the rest of the frame.

Outpainting

Expand any image beyond its original frame. Turn a square portrait into a 16:9 banner or vertical poster. Flux continues scene context naturally.

When Flux wins

Pick Flux when you need...

🎯

Exact reproducibility

When a client needs the same image regenerated weeks later, only Flux gives you that with seed locking.

🖌️

Surgical edits

When 90% of the image is right and 10% needs a fix. Inpainting beats re-rolling.

📐

Aspect-ratio expansion

When you have a portrait shot but need a banner. Outpainting extends the scene without re-shooting.
