Alibaba Z-Image Turbo
Z-Image — The 5-Credit AI Image Generator
Alibaba’s efficient 6B turbo model: photorealistic 1K images at the lowest credit price on the platform.
Z-Image is Alibaba Tongyi Lab’s efficient image model, released on November 27, 2025, and the cheapest generator on this platform at 5 credits per image. That is a quarter of the price of anything else here: the Standard plan’s 1,500 monthly credits buy 300 Z-Image generations. Despite the price, Z-Image holds its own on photorealism, especially portraits, and renders text in both English and Chinese.
What is Z-Image?
Z-Image comes from Alibaba’s Tongyi Lab and takes the opposite bet from the giant flagships: a compact 6-billion-parameter network (the Turbo variant) that produces an image in just 8 sampling steps. Alibaba reports quality comparable to closed models three times its size, and sub-second inference on data-center hardware.
Its strongest suit is photorealistic people. Portraits come out with believable skin and lighting rather than the plastic AI sheen, which is unusual at this parameter count. It also handles bilingual text rendering in English and Chinese, a rarity outside the top text models.
The model is open source, which is why it is also popular in the local-GPU community: it runs on a consumer 16GB card. Here you get the hosted version with no setup, at 1K resolution in five aspect ratios.
Z-Image is text-to-image only: it does not accept reference images. Prompts cap at 1,000 characters, so keep briefs tight. When a draft deserves editing or higher resolution, move it to FLUX.1 Kontext for edits or regenerate the concept with a 4K-capable model.

Yes, photorealistic people are its published strength. Alibaba tuned the model for high-fidelity portraits, and it beats models several times its size on that benchmark.
Why is Z-Image so cheap?
