Efficient open-weights image model that runs on 8GB consumer GPUs

FLUX 3 Image Klein is a 5.6-billion-parameter open-weights image generation model designed to run efficiently on consumer-grade hardware with just 8GB of VRAM. Despite having 38% fewer parameters than its predecessor, it delivers performance surpassing proprietary competitors. The model supports native 4K image generation, pixel-precise editing capabilities, and multi-reference image generation, making professional-grade AI image creation accessible to users with modest hardware setups.
