FLUX.3 Image Klein: a 5.6B open-weight image model that fits on an 8GB GPU — and what BFL's numbers mean for your pipeline

Automated excerpt

Black Forest Labs' October 15 release, FLUX. 3 Image Klein, is an attempt to delete both taxes at once — a 5. 6B-parameter open-weights model that, in its INT8 build, runs on an 8GB VRAM card. FLUX. 3 Image Klein is the small sibling of BFL's FLUX. 3 Image family. Local speed (BFL/NVIDIA-reported): the distilled model with the INT8 build generates a 1MP image in about 4 seconds on an RTX 5090 and under 9 seconds on an RTX 4070 through ComfyUI.
