Black Forest Labs has released FLUX.3 Image Klein, an open image generation model available on Hugging Face. This model supports text-to-image, multi-reference image-to-image, and bounding-box layout control. Optimized checkpoints allow for rapid image generation, with distilled versions producing a 1024x1024 image in approximately two seconds on an H100 GPU. The model is integrated into the Diffusers library, enabling users to easily generate images and train custom LoRAs. AI
IMPACT Accelerates open-source image generation capabilities with multi-modal control and efficient inference.
