We’re excited to announce the day-0 native support for Z-Image, a powerful image-generation foundation model, in ComfyUI! The non-distilled version serves as the core foundation for the Z-Image family, offering enhanced creative control and the potential for community fine-tuning.
Z-Image: A Foundation for Creative Freedom
As the non-distilled raw checkpoint of the Z-Image family, it preserves the full generative potential of the architecture. Unlike its distilled counterpart, Z-Image-Turbo, which prioritizes speed, the base model requires 30-50 steps with cfg 3~5 for optimal quality, resulting in longergeneration times but with significantly richer visual details and a higher artistic ceiling.
Model Highlights
Diverse Aesthetics: Broader range of artistic styles with exceptional photorealistic quality
Foundation for Fine-tuning: Ideal base model for community fine-tuning and specialized development
Effective Negative Prompts: Highly responsive to negative prompts for precise control
Enhanced Diversity: Higher generation diversity for more creative and varied results

13.3 Seconds / 1024×1024 image (30 Steps) on NVIDIA RTX Pro 6000 Blackwell
A low-angle, close-up fashion portrait featuring an African American man and a Latina woman standing side by side, leaning gently toward each other to create a natural visual focus. The high-saturation, crisp blue sky contrasts sharply with their all-white outfits—his textured polo shirt and her softly creased hoodie—while harsh midday sunlight casts sharp, defined shadows on their skin and clothing, adding depth and dimension. With relaxed, cool expressions and lazy gazes directed at the camera, the image blends vibrant street style with sophisticated visual appeal against the clean, vivid backdrop of sky and white.
A retro film photograph with soft grainy texture and warm golden sunset tones freezes a romantic road trip moment: a young Latino couple sits in the front of a vintage car, the girl with freckled cheeks glowing delicately in backlight turns sideways to the boy with a gentle smile and affectionate eyes, he gazes intently at her in half-profile, his dark curly hair with a soft velvety finish in the warm light; sun-dyed golden suburban vegetation blurs outside the window, hazy greenery echoing the car’s warm glow, the whole scene in low-saturation warm brown and light gold exuding the lazy, loving vibe of a summer dusk.
A close-up portrait shot. The Turkish man in the frame has thick, dark brown curly hair, with naturally curly strands that have a fluffy texture. His facial features are three-dimensional and deep-set, with light brown eyes looking calmly at the camera, soft lip color, and stubble on his chin with a natural textured feel. His overall demeanor is composed yet slightly gentle. He is wearing a wine-red textured shirt with folds, and the texture of the fabric shows delicate light and dark layers under the soft natural light. The background is blurred dark green vegetation. The low-saturation cool-toned background forms a harmonious contrast with the warm-toned skin and clothing colors. The entire image is bathed in natural and soft light, retaining the authentic texture of the portrait while exuding a serene atmosphere.
An office lobby in the style of Álvaro Siza. The space features clean, simple lines with a sense of fluidity. The walls are made of textured, light - colored concrete, perhaps with a slightly rough finish that gives an organic feel. There are large, irregularly - shaped windows that allow natural light to filter in at interesting angles, casting geometric shadows on the floor. The floor is composed of large, monochromatic tiles, either in a light gray or beige. In the center, there’s a unique, sculptural reception desk crafted from a combination of wood and metal, with smooth curves that echo the overall organic design. Along the walls, there are a few pieces of modern art, simple in form but rich in expression. Some potted plants add a touch of greenery, bringing life to the space, and the lighting fixtures are minimalistic, providing soft, ambient illumination.

A contemplative portrait defined by a balanced, organic composition: the pale-haired woman’s gaze drifts softly to the left, her angular profile framed by oversized, stylized lily pads and tall, delicate blooms that fill the negative space, creating a gentle visual rhythm that anchors her figure to the natural elements. Her blush-kissed cheeks and the earthy, floral-patterned cloak blend seamlessly with the muted off-white backdrop, emphasizing the intimate, dreamlike harmony between the subject and her botanical surroundings.
A bold pop art portrait: a woman with voluminous dark hair and vivid red lips holds a cherry-red lollipop, her wide, expressive eyes looking upward. The high-contrast, comic-book style uses sharp ink outlines, flat blocks of color, and a classic yellow halftone background, creating a vibrant, retro feel.
Very nice, thanks! But why z_image_bf16.safetensors and z_image_turbo_bf16.safetensors are booth 12GB in size?
