# Z-Image

ID: tongyi-mai/z-image
Type: image generation
Vendor: Tongyi-MAI
Released: 2026-01-27
Commercial use: allowed
Description: Tongyi-MAI Z-Image is a 6B single-stream DiT foundation model for high-quality text-to-image generation with strong style coverage and prompt adherence.

## Modes and inputs
- Text → Image (`txt->img`)
  - Prompt only, no input images
- Image → Image (`img->img`)
  - any image: up to 1

## Output
- Aspect ratios: 1:1, 9:7, 7:9, 4:3, 3:4, 3:2, 2:3, 16:9, 9:16, 21:9, 9:21. Other ratios snap to the closest one. Without `size` (or with `"auto"`), Mynth picks a ratio for the prompt.
- 4K: no
- Negative prompt: not supported (dropped, no error)

## Pricing (USD)
- Per image: $0.020
- Per input image: Free, charged once for each image it goes into
- Only successful results are charged.

## Usage
Set the request's `model` field to `tongyi-mai/z-image`. Always pass it explicitly.
