Welcome FLUX.3 Image Klein in Diffusers
Black Forest Labs’ FLUX.3 Image Klein launches with day-one Diffusers support for text-to-image generation, multi-reference image-to-image generation, and bounding-box layout control. Open checkpoints include a distilled model using 16 steps without CFG and a base model using 50 steps with CFG; the distilled model generated a 1024 × 1024 image in 1.93 s on an H100 in the reported benchmark. Hugging Face provides quantized loading examples, LoRA training scripts, and workflows for customizing its Modular Diffusers pipeline.
Why it matters: The runtime measurements and quantization guidance help developers assess hardware requirements, including how reference images increase generation time and when lower precision reduces memory without improving speed.
