FAQ from Z Image
What is Z-Image?
Z-Image is a powerful AI model based on the S3-DiT architecture, capable of generating photorealistic images and accurately rendering bilingual texts in Chinese and English, achieving or surpassing the performance of leading competitors in just 8 steps.
What is special about the architecture of Z-Image?
Utilizing a scalable single-stream DiT (S3-DiT) architecture, it unifies text, visual semantic tags, and image VAE tags into a single input stream at the sequence level, maximizing parameter efficiency compared to dual-stream methods.
How fast is Z-Image?
It offers sub-second inference latency on enterprise-grade H800 GPUs, with most generations taking only 2 seconds (8 steps) on NVIDIA A10 GPUs, and 2-3 seconds on consumer-grade GPUs like RTX 3090/4090, while mid-range cards take 4-5 seconds.
Can Z-Image accurately render bilingual text?
It can accurately render text in Chinese and English while maintaining facial realism and overall aesthetic composition, delivering high-quality text rendering even in challenging scenarios with small fonts.
What is the Prompt Enhancer (PE)?
The Prompt Enhancer uses structured reasoning chains to inject logic and common sense, enabling the model to handle complex tasks (such as the 'chicken and rabbit in the same pen problem') or visualize classical Chinese poetry, inferring potential intent even from vague instructions.
How does Z-Image perform compared to competitors?
According to the Elo-based human preference evaluation from the Alibaba AI Arena, Z-Image demonstrates high competitiveness in comparison to other leading models, achieving state-of-the-art results among open-source models.
How to achieve the best results with Z-Image?
Clearly specify bilingual text requirements for accurate rendering, describe lighting, shadows, and textures for photorealism, utilize the prompt enhancer for complex creative tasks and reasoning, and take advantage of the quick 8-step generation for rapid iteration.
