FLUX.3 Klein puts fast layout-controlled image generation in Diffusers
Developers can now generate images, edit multiple references, and control layout from Diffusers with FLUX.3 Image Klein. Its distilled checkpoint makes a 1024 × 1024 image in about 2 seconds on an H100, using 16 steps by default. Bounding boxes in the prompt place subjects or move parts of a reference image, while NVFP4 and FP8 weights support smaller GPUs.
