šŸ’” Pro Tip: Check these requirements before starting to avoid deployment issues with Z-Image local setup.

Step 1: Download ComfyUI for Z-Image Deployment

ComfyUI Desktop has simplified the Z-Image installation process significantly. No complex Python environments needed!

Download ComfyUI

Visit the official ComfyUI download page and select your platform:

  • macOS (Apple Silicon or Intel)
  • Windows (GPU or CPU)
  • Linux

The ComfyUI Desktop application includes everything needed for Z-Image local deployment.

Step 2: Download Z-Image Models (21GB Total)

For successful Z-Image local installation, you need three model files:

1. Text Encoder (Qwen 3 4B)

# Download to: ComfyUI/models/text_encoders/
https://huggingface.co/Comfy-Org/z_image_turbo/resolve/main/split_files/text_encoders/qwen_3_4b.safetensors

2. Diffusion Model (Z-Image Turbo BF16)

# Download to: ComfyUI/models/diffusion_models/
https://huggingface.co/Comfy-Org/z_image_turbo/resolve/main/split_files/diffusion_models/z_image_turbo_bf16.safetensors

3. VAE (Autoencoder)

# Download to: ComfyUI/models/vae/
https://huggingface.co/Comfy-Org/z_image_turbo/resolve/main/split_files/vae/ae.safetensors

Model File Organization

Place downloaded files in the correct ComfyUI directories: ComfyUI/ ā”œā”€ā”€ models/ ā”‚ ā”œā”€ā”€ text_encoders/ ā”‚ ā”‚ ā””ā”€ā”€ qwen_3_4b.safetensors ā”‚ ā”œā”€ā”€ diffusion_models/ ā”‚ ā”‚ ā””ā”€ā”€ z_image_turbo_bf16.safetensors ā”‚ ā””ā”€ā”€ vae/ ā”‚ ā””ā”€ā”€ ae.safetensors

šŸ“¦ Storage Note: Total download size is approximately 21GB. Ensure sufficient disk space for Z-Image local deployment.

Step 3: Download Z-Image Workflow Configuration

The Z-Image ComfyUI workflow is pre-configured for optimal performance:

Get the Official Workflow

Visit the Z-Image Turbo documentation to download the workflow JSON file.

This workflow includes:

  • Optimized node connections
  • Proper model loading sequences
  • Recommended generation parameters
  • Sample prompts for testing

Step 4: Configure Z-Image Model Paths in ComfyUI

After downloading models for Z-Image local installation:

  1. Launch ComfyUI Desktop
  2. Load the Z-Image workflow (drag & drop the JSON file)
  3. Verify model paths in each node:
    • Text Encoder node ā†’ qwen_3_4b.safetensors
    • Diffusion Model node ā†’ z_image_turbo_bf16.safetensors
    • VAE node ā†’ ae.safetensors

If models don't appear in dropdowns, check file locations match the directory structure above.

Step 5: Start Generating Images with Z-Image

Your Z-Image local deployment is complete! Time to create stunning images:
