What Z-Image Can't Do (Yet)
Every AI model has limitations. Here's what you should know before choosing Z-Image.
Image Editing Not Supported
Z-Image currently cannot edit or modify uploaded images. You can only generate new images from text prompts.
NSFW Content Prohibited
Z-Image strictly prohibits adult, violent, or harmful content generation. This applies to all hosted services.
Hardware Requirements
Running locally requires a GPU with at least 16GB VRAM. Mid-range cards will work but with 4-5 second generation times.
Batch Processing Limits
API services limit batch requests to 4 images maximum per call. Inference is capped at 8 steps.
Speed Varies by Hardware
Sub-second inference only applies to enterprise H800 GPUs. Consumer cards take 2-5 seconds depending on tier.
When to Use Z-Image
A decision guide to help you choose the right tool for your needs
Use Z-Image When:
- Bilingual text (Chinese + English) rendered accurately in images
- Speed matters - you want rapid iteration and quick prototyping
- Photorealistic quality without complex prompt engineering
- Budget is limited - free tier or $0.02/image is acceptable
- Commercial usage rights (Apache-2.0 licensed)
- Open-source with the option to self-host
Consider Alternatives When:
- Edit existing images (use Photoshop, GIMP, or dedicated editing AI)
- NSFW or adult content (not supported on hosted services)
- Mid-range GPU and need guaranteed sub-second speed
- Video generation (use Kling, Runway, or similar)
- Highly specific artistic styles (Midjourney may be better)
- Real-time streaming generation (not yet supported)
Quick Decision Guide
If your goal is to create marketing materials with both Chinese and English text:
→ Z-Image is your best choice. Its bilingual text rendering is industry-leading among open-source models.
If you need to rapidly iterate on visual concepts for a product:
→ Z-Image's 8-step generation (2-3 seconds) enables much faster workflow than 30-60 second alternatives.
If you want to fine-tune a model for your specific style:
→ Use Z-Image-Base (open-source) as your foundation. It's designed for community fine-tuning.
