Black Forest Labs has released FLUX 3 Image Klein with open weights, now live on Hugging Face. The company claims frontier-model image quality from just 5.6B parameters, runnable on a single consumer GPU.
Key features: native 4K resolution, bounding box controls, and pixel-perfect editing, supporting both text-to-image and image-to-image. The HF Collection already includes several variants: the main flux-3-image-klein model (6B, 3.2k downloads already), a base version, a companion pup image-text model (9B), and a ComfyUI-specific flux-3-image-klein-comfy.
