Flux 2 Klein 9B
Flux 2 Klein 9B is BFL's compact image generation model, striking a balance between speed and quality at the 9-billion parameter scale. It generates images fast enough for interactive creative workflows — previewing compositions, testing prompts, and iterating on concepts — while maintaining enough quality that outputs are usable for many production scenarios.
Klein 9B is the sweet spot for creative teams that need rapid iteration without completely sacrificing image quality. It's fast enough for real-time concept exploration but detailed enough that promising results can go straight to use without regeneration on a larger model.
