01 / CAPABILITIES
FLUX 3 Image Klein combines up to ten reference images. For a useful first experiment, assign each reference one job: subject, wardrobe, setting or color. This makes it easier to see which instruction needs changing.
Bounding-box controls guide placement and localized edits. Plan the headline area before generating an advertisement, then inspect the edges around the changed object.
Text-to-image and instruction-based editing share a model. Change one thing at a time when refining a composition so you can compare successive results.
Native output reaches 4K. View lettering, jewelry and repeated patterns at full size; a striking thumbnail is only the beginning of an image review.
BFL offers an API and downloadable Base and Distilled weights. The distilled version uses fewer sampling steps; local performance depends on hardware, precision and the complete pipeline.
BFL recommends its prompt-upsample workflow. Describe the intended subject, framing and constraints clearly; keep a short checklist to evaluate each result.

03 / CREATIVE STARTING POINTS
Start with these prompt ideas and adapt the subject, style and setting to your project.
A cobalt-blue ceramic perfume bottle on pale limestone, hard morning sunlight from the left, a crisp curved shadow, quiet cream backdrop, leave the upper third empty for a headline, no text or logos.
A tiny observatory on the back of a sleeping whale, midnight-blue paper texture, copper-colored stars, restrained screen-print palette, clean silhouette, wide composition, no lettering.
Keep the subject, pose, camera angle and background unchanged. Replace only the jacket with a dark green corduroy jacket. Preserve the direction and softness of the original light.
