Frequently Asked Questions

What hardware can smoothly run Z-Image? How to solve insufficient memory?

+

Consumer-grade RTX 3060 graphics cards can run smoothly. RTX 4090 generates 1024×1024 images in just 2.3 seconds with 13GB memory usage.

If you encounter insufficient memory:

  • First reduce resolution to 384
  • Reduce batch processing to 1
  • Use mixed precision, 4bit quantization to compress memory
  • Enable CPU Offload to transfer some parameters to CPU

How to handle generated images that are all black or have blurry details?

+
  • All black: Mostly due to improper parameter settings, adjust resolution to 1024×1024, sampling steps to 8-9
  • Blurry details: Add lighting, material keywords in prompt, e.g., add "cinematic style, golden hour lighting"
  • Proportional abnormalities: Detail character descriptions, clarify height, limb movements

Are there licensing restrictions for using Z-Image in commercial scenarios?

+

Individuals, studios and enterprises can use it for free commercially. When distributing after secondary development, keep copyright notices and follow relevant license regulations.

Do images generated by Z-Image involve copyright issues?

+

If generated images are used commercially, conduct content review, avoid adult content, infringing elements and other violations; also suggest keeping the prompts and parameter records used for generation to handle possible copyright checks.
