Le modèle Z Image fp8 est une version quantifiée du modèle Z-Image, optimisée pour fonctionner avec ComfyUI. Il utilise des formats FP8 (comme fp8-e4m3fn ou fp8-e5m2) pour réduire considérablement les besoins en mémoire VRAM tout en conservant une qualité d'image élevée, ce qui le rend accessible même sur des GPU grand public. Ce modèle excelle dans la génération d'images détaillées et stylisées, notamment pour des portraits ou des scènes complexes avec des textures riches et des poses précises. Ses cas d'usage incluent la création artistique, la mode, ou tout projet nécessitant des rendus visuels sophistiqués avec des contraintes matérielles limitées. Ce qui le distingue, c'est son équilibre entre performance et accessibilité, permettant une utilisation fluide sans sacrifier la finesse des détails.
This is the fp8-e4m3fn-scaled / fp8-e4m3fn and fp8-e5m2-scaled / fp8_e5m2 quantized versions of the Z-Image model, optimized for ComfyUI workflows. These quantized formats significantly reduce VRAM requirements while maintaining high image quality, making the model more accessible for consumer-grade GPUs.

BF16 / fp8-e4m3fn An Asian woman is seated in a commanding, symmetrical pose on a stark, matte white architectural block, viewed from a distinct low angle looking upward, which elongates her silhouette against the background. She is attired in a structured, high-fashion suit constructed from heavy, lustrous silk brocade in a rich emerald green, embossed with a complex, swirling floral texture that catches the studio illumination. The jacket features sharp, exaggerated shoulder pads and wide lapels, tapering slightly at the waist, while the matching trousers are cut with an extremely wide leg, draping in thick, vertical folds that obscure the shape of her lower limbs. Her legs are positioned wide apart, knees angled outward well beyond the width of her shoulders, creating a distinct triangular negative space between her inner thighs. Her hands rest deliberately on the front upper edge of the white cube, located centrally between her legs, with palms flat against the surface and long, slender fingers draping slightly over the rim. Her head is tilted slightly downward to maintain direct eye contact with the low-positioned camera, her expression stoic and poised, featuring subtle contouring makeup and a satin-finish berry lipstick. Her straight black hair is parted precisely in the center and slicked back tightly, falling in a clean line down her back. The lighting is crisp and directional, casting a defined shadow behind her on the seamless, pale grey background while accentuating the weave of the fabric and the sharp, geometric corners of the seating block. seed: 539314584494176 Steps:30 | CFG:4 | Euler
