FLUX.2 [klein] 9B KV

Black Forest Labs
by Black Forest Labs

FLUX.2 [klein] 9B KV is a KV-cache optimized variant of the Klein 9B model that caches reference image key-value pairs after the first denoising step, skipping redundant computation on subsequent steps. This delivers up to 2.5x faster inference for multi-reference editing tasks while retaining all capabilities of the standard Klein 9B, including sub-second text-to-image and advanced editing in 4 steps.

Clockwork Aviary in Fog

Clockwork Aviary in Fog

An immense Victorian-era glass aviary perched on black seaside cliffs at dawn, filled with intricate brass songbirds, suspended gyroscopes, winding keys, and delicate clockwork vines curling around iron arches. Pale fog pours through cracked panes while warm amber lamps glow inside the structure, contrasting with the cold blue ocean beyond. A lone caretaker in a long cobalt coat stands on a narrow bridge leading into the aviary, tiny against the grand scale. Highly detailed mechanical design, cinematic wide shot, layered depth, elegant symmetry with subtle asymmetry, textured metal, misty atmosphere, refined color grading, crisp focal detail, imaginative realism.

Salt-Flat Pilgrimage Caravan

Salt-Flat Pilgrimage Caravan

A sweeping fantasy caravan crossing an endless salt flat at first light, drawing visual cues from the reference images: nomads wearing layered indigo garments with mirrored embroidery and wrapped headpieces, traveling beside tall horned pack beasts with shaggy coats and suspended bundles. Crystalline salt polygons shimmer under low golden light, distant copper mesas rise on the horizon, faint dust ribbons trail behind the caravan, reflective ground creates subtle mirrored silhouettes, cinematic scale, rich environmental storytelling, finely detailed textiles, elegant creature anatomy, atmospheric depth, high realism with painterly finish
