Can I generate images from text prompts in Z Image AI?

Yes—write a prompt for what you want and generate from text-to-image. You can then refine your prompt and run another generation if needed.

Can I edit an existing photo with a prompt?

Yes—upload a reference photo and use image-to-image to restyle, edit, swap elements, or reimagine the scene while keeping your subject.

What’s the difference between Text to Image and Image to Image?

Text to Image creates a new image from your description. Image to Image transforms an uploaded photo using your prompt, focusing changes on the reference subject.

How do I choose the right AI model?

Pick GPT Image 2 for highest-quality output and accurate text rendering, Nano Banana 2 for precise instruction-based edits, and Z-Image Turbo for the fastest draft iterations. For photorealistic product-style scenes, use Seedream 4.5, and for layout/infographics use Seedream 5.0 Pro or Grok Imagine 2.0.

How long does generation take?

Generation time varies by model and quality settings. Z-Image Turbo is designed for 2–5 second drafts, while GPT Image 2 includes different quality tiers with higher quality taking longer.

Can I use the generated images commercially?

Yes—images you generate are for your use commercially, with no watermark and no attribution required.
