Frequently asked questions
What is Z-Image?
Z-Image is a powerful AI model with strong capabilities in photorealistic image generation, accurate rendering of both Chinese and English text, and robust adherence to bilingual instructions. It achieves performance comparable to or exceeding leading competitors with only 8 steps.
What makes Z-Image's architecture special?
Z-Image uses a Scalable Single-Stream DiT (S3-DiT) architecture that unifies text, visual semantic tokens, and image VAE tokens at the sequence level as a unified input stream. This maximizes parameter efficiency compared to dual-stream approaches.
How fast is Z-Image?
Z-Image offers sub-second inference latency on enterprise-grade H800 GPUs. On NVIDIA A10 GPUs, most generations take a maximum of 2 seconds with just 9 steps. On consumer GPUs like RTX 3090/4090, it takes roughly 2-3 seconds, while mid-range cards take 4-5 seconds.
Can Z-Image render bilingual text accurately?
Yes, Z-Image excels at accurately rendering Chinese and English text while preserving facial realism and overall aesthetic composition. It demonstrates strong compositional skills and typography sense, even in challenging scenarios with small font sizes.
What is the Prompt Enhancer (PE)?
The Prompt Enhancer uses a structured reasoning chain to inject logic and common sense, enabling the model to handle complex tasks like the 'chicken-and-rabbit problem' or visualizing classical Chinese poetry. It can infer underlying intent even from ambiguous instructions.
How does Z-Image perform against competitors?
According to Elo-based Human Preference Evaluation on Alibaba AI Arena, Z-Image shows highly competitive performance against other leading models, while achieving state-of-the-art results among open-source models.
