Black Forest Labs releases FLUX.3 Image Klein with bounding-box layout control in Diffusers
Black Forest Labs published FLUX.3 Image Klein to the Hugging Face Hub and ships open checkpoints that run in Hugging Face Diffusers. The model supports text-to-image and multi-reference image-to-image generation, adds bounding-box layout control for region placement and image edits, includes a distilled checkpoint (1024×1024 ~2s on an H100, 16 steps by default), quantized single-file transformer weights (bf16, fp8r, nvfp4), and LoRA/DreamBooth training scripts.
