Flux 2 Klein models are now available on the RunDiffusion Runnit Platform and in RunDiffusion Open Source Applications. These new models expand the Flux 2 lineup with fast, lightweight options designed for interactive AI image generation and image editing workflows.
Developed by BlackForestLabs, Flux 2 Klein models are optimized for low latency, efficient inference, and real time creative iteration. They support both text to image generation and image editing within a single unified architecture, making them ideal for creators who need speed without sacrificing quality.
New Flux 2 Klein Models on RunDiffusion
RunDiffusion now supports the following Flux 2 Klein variants:
Flux 2 Klein 4B Distilled
A distilled, high performance model optimized for extremely fast image generation with minimal inference steps. Best suited for rapid prompt testing, early concept development, and high volume experimentation where speed is critical.

Flux 2 Klein 4B
A balanced 4 billion parameter AI image model that delivers improved detail, consistency, and prompt adherence while remaining lightweight and responsive. Ideal for iterative design workflows, concept refinement, and everyday creative use.

Flux 2 Klein 9B
The largest model in the Flux 2 Klein family, offering stronger composition, higher visual fidelity, and improved prompt accuracy while maintaining the fast, interactive performance Klein models are known for.

Why Flux 2 Klein Models Matter
Flux 2 Klein models give RunDiffusion users greater control over performance versus visual quality depending on the stage of their workflow. Creators can move quickly during ideation and experimentation, then step up to higher fidelity results without switching model families or tools.
With unified support for image generation and image editing, Flux 2 Klein models are well suited for product visualization, illustration, concept art, design exploration, and general AI image creation.
