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.
Model Highlights:
  • 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
