Flux 2 Klein

What is Flux 2 Klein?

Flux 2 Klein is a lightning-fast image generator from Black Forest Labs. It creates and edits images in under 0.5 seconds, combining text-to-image, inpainting, and multi-reference editing in one compact model. Pick a 4B Apache 2.0 build for open-source commercial use or a 9B high-quality variant for sharper results. Distilled versions prioritize speed for real-time previews, while base variants keep full training signal for fine-tuning. It runs on consumer GPUs and integrates with ComfyUI, Diffusers, and common deployment platforms for easy use.
