About
FLUX 3 Image Klein is an image-generation model from Black Forest Labs for developers and creative teams. It creates images from text prompts and supports instruction-based image editing, reference-image guidance with up to 10 images, and output at resolutions up to 4K. The 5.6-billion-parameter model is available through the Black Forest Labs API and as downloadable weights for local inference. Base and step-distilled variants support different workflows, with additional quantized formats for local deployment. Use it for creative production, design exploration, prototyping, and image-generation features in applications. Local and commercial use are subject to the model license. API usage is charged per generated image, with pricing varying by resolution.

About
FLUX.2 [klein] is the fastest member of the FLUX.2 family of AI image models, designed to unify text-to-image generation, image editing, and multi-reference composition into a single compact architecture that delivers state-of-the-art visual quality at sub-second inference times on modern GPUs, making it suitable for real-time and latency-critical applications. It supports both generation from prompts and editing existing images with references, combining high diversity and photorealistic outputs with extremely low latency so users can iterate quickly in interactive workflows; distilled versions can produce or edit images in under 0.5 seconds on capable hardware, and even compact 4 B variants run on consumer GPUs with about 8–13 GB of VRAM. The FLUX.2 [klein] family comes in different variants, including distilled and base versions at 9 B and 4 B parameter scales, giving developers options for local deployment, fine-tuning, research, and production integration.
