Z-Image ComfyUI Workflow Example

Z-Image is a 6B parameter efficient image generation foundation model with single-stream diffusion transformer, offering sub-second inference latency.

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

Run on ComfyUI Cloud

Portable or self deployed users

Make sure your ComfyUI is updated.

• Download ComfyUI
• Update Guide

Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated. (Desktop version’s update will delay sometime)

If nodes are missing when loading a workflow, possible reasons:

1. You are not using the latest ComfyUI version (Nightly version)
2. Some nodes failed to import at startup

Desktop or Cloud users

• The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
• Cloud will update after ComfyUI stable release.

So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

Z-Image-Turbo Fun Union ControlNet workflow

This workflow uses the Z-Image-Turbo Fun Union ControlNet model to generate images with ControlNet guidance. It applies Canny edge detection to a reference image and uses the ControlNet to guide the generation process.
