Z-Image (造相) is a powerful and highly efficient image generation model with 6B parameters, developed by Alibaba’s Tongyi Lab. It uses a Scalable Single-Stream DiT (S3-DiT) architecture where text, visual semantic tokens, and image VAE tokens are concatenated at the sequence level to serve as a unified input stream, maximizing parameter efficiency.
Model Variants:
- 🚀 Z-Image-Turbo – A distilled version that matches or exceeds leading competitors with only 8 NFEs (Number of Function Evaluations). It offers sub-second inference latency on enterprise-grade H800 GPUs and fits within 16GB VRAM consumer devices.
- 🧱 Z-Image-Base – The non-distilled foundation model for community-driven fine-tuning and custom development.
- ✍️ Z-Image-Edit – A variant fine-tuned for image editing tasks with impressive instruction-following capabilities.
- Photorealistic Quality: Delivers strong photorealistic image generation while maintaining excellent aesthetic quality
- Accurate Bilingual Text Rendering: Excels at accurately rendering complex Chinese and English text
- Prompt Enhancing & Reasoning: Prompt Enhancer empowers the model with reasoning capabilities
- Sub-second Inference: Achieves fast generation speed on supported hardware
