Original titleblack-forest-labs/flux-3-image-klein-comfy
Black Forest Labs has released FLUX 3 Image Klein, a 5.6B open-weights model for text-to-image generation and image editing, repackaged for ComfyUI. The repository offers distilled and base transformers in BF16, int8 and NVFP4, with int8 files for GPUs such as the RTX 3070 and NVFP4 requiring a Blackwell GPU. The model takes a prompt and up to 10 reference images, and it is released under the FLUX Kommunity License, which permits non-commercial use.
The repository lists the checkpoints, VRAM-tier quantizations and step settings, which helps readers choose a build for their own GPU and workflow.
