What is Z-Image?
Z-Image is Tongyi-MAI’s open-source 6B image foundation model. It is designed as the base model in the broader Z-Image family, with a focus on prompt adherence, broad visual coverage, and downstream flexibility for fine-tuning and deployment.
What is Z-Image best for?
Z-Image works well for prompt-led image generation, poster concepts, product-style visuals, and workflows that may later move into ComfyUI, local runtimes, or other self-hosted setups.
Does Z-Image support image-to-image here?
Yes. Here, Z-Image supports both text-to-image and single-reference image-to-image. You can add one reference image when you want to preserve shape, framing, or overall visual direction.
Which aspect ratios does Z-Image support here?
Z-Image currently supports 1:1, 4:3, 3:4, 16:9, and 9:16 here, which covers common square, portrait, landscape, and social-first creative formats.
How do I write better prompts for Z-Image?
Start with the subject, then describe style, composition, lighting, materials, and any text that must appear in the image. Z-Image responds best when you clearly separate what is required from what can vary, especially for posters, product visuals, and one-reference edits.
When should I use Z-Image instead of GPT-4o or Seedream 4?
Choose Z-Image when you want an open model you can keep using beyond a hosted tool, especially if prompt control or self-hosting matter. Use GPT-4o or Seedream 4 when you mainly want their built-in style and hosted workflow.
What is the difference between Z-Image and Z-Image-Turbo?
Z-Image is the main 6B foundation model. Z-Image-Turbo is a distilled family variant optimized for faster and lighter inference, which is why many community workflows and local deployments mention Turbo specifically.
Can I use Z-Image images commercially?
The upstream Z-Image weights are released under Apache-2.0, but commercial use of generated assets still depends on your use case, review standards, and the platform terms that apply here. For production work, keep a normal legal and brand review process instead of treating model output as automatically cleared.
Is Z-Image open-source and can it be self-hosted?
Yes. Tongyi-MAI released Z-Image upstream, and the model already appears in diffusers-based paths, local runtimes, ComfyUI tooling, and workflow packs. That makes it much easier to study, deploy, and adapt than a closed hosted-only model.
