Running the Z-Image Workflow Locally

This guide explains how to run Alibaba’s Z-Image workflow inside Promptus, providing a streamlined, no-code experience for ComfyUI users. Whether you are using the Promptus Web interface or the Desktop App, follow these steps to master high-performance image generation.

📋 1. Prerequisites

Before you start, ensure your environment meets these requirements:

• App: Latest version of Promptus.
• Hardware: 12–16GB VRAM GPU recommended (Quantized GGUF versions can run on 4GB VRAM).
• Automation: Promptus automatically handles workflow loading, model downloading, and file management so you can focus on creating.

📂 2. Loading the Z-Image Workflow

Promptus includes one‑click CosyFlows templates for Z-Image:

• Z‑Image Turbo (Text‑to‑Image)
• Z‑Image Turbo (Image‑to‑Image)
• Z‑Image Turbo + LoRA Loader
• Z‑Image Turbo + ControlNet

Steps:

1. Open Promptus.
2. Navigate to the Workflows tab.
3. Click Import Workflow and select Z‑Image Turbo.
4. The visual pipeline (UNet Loader, CLIP Text Encode, KSampler, etc.) will appear on your canvas.

📥 3. Model Configuration

Promptus detects missing models and prompts you to download them automatically.

💡 Tip: Simply click "Download All Models" and Promptus will place them in the correct directories for you.

✍️ 4. Prompting & Sampling

To get the best results from the Z-Image architecture, use these optimized settings:

• Positive Prompt: "A cinematic portrait of a young woman standing in warm sunset light, shot on a 50mm lens, ultra-realistic, detailed skin texture."
• Steps: 6–9 (Z-Image Turbo is highly efficient).
• CFG: 1.0–3.0.
• Sampler/Scheduler: Euler or Euler A / Simple.

🖼️ 5. Image-to-Image (img2img) Capabilities

Transform existing visuals using the dedicated img2img workflow:

1. Add your image via the Load Image node.
2. Adjust Denoise Strength:
   • 0.2–0.4: Subtle retouching.
   • 0.5–0.7: Medium style changes.
   • 0.8–1.0: Heavy transformation (e.g., Anime to Realism).

🎨 6. Using LoRAs

Enhance your style or characters by adding LoRAs:

1. Add a LoRA Loader node after the UNet.
2. Set strength between 0.5–1.0.
3. Include specific trigger words in your positive prompt.
4. Note: You can chain multiple LoRAs for combined effects.

✨ Best Practices for Success

• Keep Prompts Concise: Z-Image understands complex concepts without "prompt salad."
• Camera Styles: Use keywords like 50mm, IMAX, or Fujifilm to influence the render's "feel."
• GPU Optimization: If you experience slow renders, switch to the Promptus GPU Marketplace for high-end cloud power.

🏁 Conclusion

You are now ready to run Z-Image without a complex manual ComfyUI setup. Promptus provides the infrastructure; you provide the vision.
