Original titleFLUX 3 Image Klein in ComfyUI: 5.6B Open Weights
AISummary
Black Forest Labs' FLUX 3 Image Klein is a 5.6B-parameter open-weights image model now available in ComfyUI, in base and distilled (turbo) forms.
Paired with INT8 ConvRot quantization and the distilled model, 1024×1024 text-to-image generation runs 4.3× to 9.3× faster than the BF16 50-step baseline, with the largest gains on consumer GPUs. On an RTX 5070, one image drops from 71 seconds to under 8.
AIWhy it matters
The post gives the model's size, its base and distilled forms, and measured speedups on consumer GPUs, which helps readers judge whether it fits their hardware.
