FLUX 3 Klein Image Base

FLUX 3 Klein Image Base

FLUX 3 Klein Image Base uses Black Forest Labs' full, non-distilled FLUX 3 Klein checkpoint for image generation and editing. A written description defines an image for generation. For editing, supplied references provide the source material and a natural-language instruction describes the desired result.

The model can combine subjects and scenes from separate reference images. It also supports text within images and bounding-box layout control, giving element placement a defined role in the composition. These capabilities are useful when a visual brief includes both specific source material and a planned arrangement.

What it's good for

Promotional concepts can combine a referenced subject with a setting and integrated lettering. Layout control helps develop compositions where the position of those elements matters to the design, such as artwork built around a headline.

Editorial illustration and concept development can use generation to explore a written idea, followed by reference-guided edits to assemble a more specific scene or reposition its elements.
