Diffusers adds full Flux.3 Image Klein support: FP8/NVFP4 quantized inference and bbox layout control
RisingSayak · x · 2026-10-15
The Hugging Face Diffusers team announced full support for Flux.3 Image Klein: both distilled and non-distilled pipelines are implemented as modular diffusers pipelines, with support for loading quantized FP8r and NVFP4 checkpoints for inference, plus a dedicated backend for them.
Beyond regular T2I and I2I workflows, the model supports layout control — you can specify bounding box coordinates in the prompt for precise control over element placement in outputs.
