Changing one object without rebuilding the scene is a control problem as much as a generation task. Black Forest Labs’ October 15 FLUX 3 Image Klein release brings both tasks to a smaller model.
References and defined regions
The 5.6-billion-parameter model accepts up to ten reference images. Bounding boxes guide placement or confine edits. API pixel restoration preserves unedited regions exactly.
Match the variant to the work
A base model supports adaptation, while a step-distilled version targets lower latency. BFL says the INT8 build runs through ComfyUI or Diffusers on NVIDIA GPUs with as little as 8 GB of VRAM. The FLUX Kommunity License sets usage terms, including company-size conditions for commercial deployment.
Hazel’s assessment
I would first mark what must stay unchanged. A good edit depends on the surrounding scene as much as the replacement object. That specific task provides a better basis for choosing the model variant and hardware.
