Z-Image is Alibaba's Tongyi Z-Image-Turbo: a fast, photorealistic text-to-image model that actually renders legible English and Chinese text — posters, banners, and social graphics included. It is one of the lowest-cost models on the platform, and you call Z-Image through reApi's unified API.

Z-Image is Alibaba's Tongyi Z-Image-Turbo, a fast text-to-image model exposed on reAPI as one async endpoint with a three-parameter surface: a prompt of up to 1000 characters, one of five aspect ratios, and a content-filter toggle. It takes no image input, renders legible English and Chinese text inside the picture, and returns one image per request at a flat rate per image.
Real-world workflows and production use cases you can build and ship with this model.
Most image models turn captions into gibberish. Z-Image renders legible English and Chinese type, so OOTD collages, promo graphics, and social cards come back with the words spelled right and laid out where you asked. Write the copy in your prompt, set the aspect ratio, and it composes art and text together in one fast, low-cost generation.

It produces lifelike portraits and outfits with refined lighting and clean skin texture — strong enough for lookbooks, e-commerce, and street-style shots. At a compact 6B scale it stays fast and cheap, so you can iterate on poses, styling, and scenes without burning your budget on a single hero image.
It is built for images where the typography matters as much as the photo. Generate magazine covers, banners, and posters with crisp English or Chinese headlines and balanced composition. Because the text stays sharp and on-layout, the output is usable as-is instead of needing a second pass in a design tool.
The reason teams reach for Z-Image is the in-image text. It renders accurate English and Chinese — small fonts and complex layouts included — where generic models smear letters. If your output has to carry words, it keeps them readable, through the same request to /api/v1/images/generations.
Z-Image-Turbo runs in minimal sampling steps, so generations come back quickly. 1 credit equals $0.001 USD and it is one of the lowest per-image rates on the platform — flat per image, so cost is a single multiply, ideal for high-volume social and e-commerce work.
Submit a Z-Image task, get a task_id back, poll until it completes. The JSON matches the OpenAI image-generations contract, so adding it is a model-id change, not a new integration. Failed and rejected requests are refunded automatically.
Both generate images from one API. Z-Image leans into legible bilingual text, photorealism, and a very low flat per-image price. Here is how the two compare on publicly documented behavior.

OpenPOST to /api/v1/images/generations with model: z-image, a prompt, and an optional aspect_ratio. Z-Image returns a task_id immediately.
OpenGET /api/v1/tasks/:id until status is completed. The Z-Image response carries the image URL; mirror it to your own storage if you need it long term, since generated links expire.
