FLUX 3 Image Klein
MODELFLUX 3 Image Klein is Black Forest Labs' open-weights image model for generation and reference-based editing, available on Runware as a distilled checkpoint and an undistilled base.
- Use
bfl:flux@3-image-kleinfor the distilled checkpoint, built for speed, andbfl:flux@3-image-klein-basefor the full undistilled checkpoint, the one to fine-tune and customize. - Both generate from text and edit from up to 4 reference images in a single endpoint.
- Output width and height range from 128 to 4096 pixels, in multiples of 16.
- Bounding boxes place, move or resize elements on a 0 to 1000 scale, each one referenced from the prompt by its id.
- Both take up to 50 steps, 16 by default on the distilled checkpoint and 50 on the base, plus a seed and four acceleration levels. The base checkpoint also takes a CFG scale and a negative prompt.
