Z-IMAGE: 6B 参数、秒级生成、0.005 美元/张

Z-Image 在速度与成本碾压 Nano Banana Pro 和 FLUX.2 Pro 的同时，真实质量到底差多少？5 个场景 15 张图真实对比，告诉你大多数时候只需要 Z-Image 就够了。

• FLUX.2 Pro 靠 32B 参数和顶级细节称霸专业圈；
• Nano Banana Pro（Gemini 3 Pro 图像版）主打多模态编辑和 真实感输出
• 而阿里巴巴开源的 Z-Image Turbo 只有 6B 参数，却号称「1 秒出图、0.005 美元一张」，还能跑在 16GB 显存的笔记本上。

Photorealistic 写真级人物#

Z-Image	Nano Banana Pro	FLUX.2 Pro

真实评价：
表现的都挺好，但是我喜欢Z-Image的审美。

提示词

Cinematic photo, summer vibes. A beautiful Chinese young girl sitting on a wooden beach deck, leaning back comfortably. She has messy blonde hair, sunglasses perched on her head, and soft makeup. She wears a white t-shirt with red graphic text and red retro gym shorts. The fabric of the shirt is light and airy. Beside her is a soft drink cup and colorful beach balls. The background features a blurred sunny beach scene with a distinctive red and white lifeguard station and blue ocean. High contrast lighting, dappled shadows from an umbrella, 8k resolution, photorealistic textures, depth of field.

杂志#

Z-Image	Nano Banana Pro	FLUX.2 Pro

真实评价：Z-Image 的杂志人物打光比较能突出主体，面部也更柔和，人物更符合我的审美。其他两个人物有点紧绷。虽然这里面要求的文字模型都渲染正确，但是Z-Image在标题下方有一些额外渲染的小字有误。

A magazine cover of a cool 20-year-old Chinese woman with wet slicked-back hair, standing under a transparent umbrella on a rain-slicked Hong Kong street at night. She wears an oversized black leather trench coat and silver hoop earrings. The background is filled with blurred red and blue neon signs reflecting on the wet asphalt. Cinematic lighting with strong contrast, Wong Kar-wai aesthetic, Kodak Portra 800 style, vibrant colors, moody atmosphere, medium shot. 8K resolution.

Magazine layout:
Title "NOCTURNE".
Cover text: "Neon Soul", "Midnight Express", "Vol. 09 | Winter 2025".
Barcode bottom. Bold sans-serif typography in white and neon red.

插画#

Z-Image	Nano Banana Pro	FLUX.2 Pro

真实评价：这三种图看上去差不多，我都很喜欢，挑不出来啥毛病。

An illustration of an anthropomorphic orange fox taking a nap on a large, soft green beanbag chair. The fox is wearing round glasses, a casual outfit with sneakers, and has a peaceful expression. Beside the chair on the floor sits a retro brown radio with a glowing dial. The art style is painterly with visible textures, resembling a modern storybook illustration. The lighting is warm and cozy, suggesting a lazy afternoon. Isolated on a plain white background. 1:1 aspect ratio

OOTD 穿搭拼图#

Z-Image	Nano Banana Pro	FLUX.2 Pro

真实评价：这个场景比较容易出图，但是不适合抠细节。OOTD的元素跟画面主角的穿着没有一个是相对应的，这一块模型都没有成功。但是单就整个场景的视觉校效果完成的都不错。感官上我还是比较喜欢Z-Image的审美和画面搭配。不过比较尴尬的是z-image的文字是瞎编乱造的。nano banana 和FLUX.2的都是正确的。Z-Image不适合让它自己想文字，还是适合提供明确的元素给它。

提示词

A 9:16 vertical screen high-end fashion illustration mood board, simulating a tablet scan effect. The background is pure hand-drawn creamy watercolor gradient paper with a faint pink grid. The visual core consists of several glossy vinyl stickers with distinct white die-cut wide borders and soft shadows. The central sticker is a photo of the user wearing a sweet date outfit, with bright lighting. On the left side is a deconstructed sticker of this outfit: a neatly folded jacket and exquisite high heels. In the bottom right corner is the key hidden layer sticker: a chic open mini-handbag revealing daily essentials like a tube of lipstick and vintage sunglasses, showcasing leather and glass textures. A Labubu art doll sticker in pink tones that echoes the user's clothing is lying on a hand-drawn speech bubble. The surroundings are decorated with crayon-textured hand-drawn hearts, sparkle symbols, and scribbled Chinese calligraphy annotations for OOTD. The image contains absolutely no human hands, pens, or physical desktop backgrounds—pure flat art illustration.

创意广告#

Z-Image	Nano Banana Pro	FLUX.2 Pro

真实评价：Nano banana 的创意最优秀，FLUX.2 Pro次之。 Z-Image 最拉跨，几乎没有创意，文字也是乱的。可见z-image还是比较适合用户的提示词给出明确约束的场景。像这种天马行空的概念创作还是需要具有深度理解能力的Nano Banana 来做。

提示词

Creative 3D ad for oreo, with surreal object made from it, matching background color, real slogan below, logo on top, miniature person interacting, minimal and clever concept

总结#

z-image 凭借其轻量化参数，可以在快速生成图片的时候，保持较高的质量。z-image 在人物生成，细节丰富度，真实性上并不比Nano Banana Pro和FLUX.2 Pro 差，但是在文字渲染和创意生成上与上述模型还有些差距。考虑到它的成本和生成速度，在大多数任务上，z-image还是很优秀的
