Alibaba Tongyi Wanxiang 2.7 unified interface for image generation and editing. Covers wan2.7-image-pro (professional, text-to-image up to 4K) and wan2.7-image (standard, up to 2K) tiers. The two tiers share the same interface via internal tier switching, and are exposed as a single model externally. Six call modes:

Text-to-image (generate) — prompt only, with optional thinking mode
Image-to-image (image2image) — Free-form generation from a single reference
Image edit (edit) — Inpainting / style transfer / element replacement
Multi-image reference (reference) — Fuse up to 9 reference images
Image group (group) — enable_sequential for comic strips / storyboards, max n = 12
Interactive editing (interactive_edit) — bbox_list targeted region editing (exclusive)

Per-image pricing, unified at $0.02295 per image.

Available Models

Model ID	Description
`wan2.7-image`	Alibaba Tongyi Wanxiang 2.7. Unified interface for text-to-image / image-to-image / editing / multi-image reference / image groups / interactive bbox editing. Up to 4K

Common Parameters

string

required

Choose one from the Available Models list. Currently wan2.7-image

string

default:"generate"

Operation type. Options:

generate — Text-to-image (default)
image2image — Image-to-image (use with single image_urls)
edit — Image editing (inpainting / style transfer)
reference — Multi-image reference fusion (up to 9)
group — Image group generation (use with enable_sequential)
interactive_edit — Interactive bbox editing (use with bbox_list)

string

required

Image description. Supports Chinese and English. For image-group mode, storyboard-style descriptions work best

integer

default:"1"

Number of images. Standard mode is bounded by service-side limits; image-group mode (enable_sequential: true) allows up to 12

integer

default:"-1"

Random seed. -1 for random; a fixed value reproduces similar results

string

default:"1:1"

Aspect ratio, 7 options:

1:1 — Square
16:9 / 9:16 — Widescreen landscape / portrait
4:3 / 3:4 — Standard landscape / portrait
3:2 / 2:3 — Camera ratio landscape / portrait

string

default:"2K"

Output resolution. Options: 1K / 2K / 4K. Note: image-group mode caps at 2K

string[]

Array of reference image URLs:

image2image / edit / interactive_edit: 1 image
reference: 2-9 images

string

Webhook callback URL, invoked when the task reaches a terminal state. See Callback Mechanism

string[]

Subscribed callback event types. See Callback Mechanism

Model-Specific Parameters

boolean

default:"false"

AI-generated watermark

boolean

default:"true"

Thinking mode — when enabled, the model performs visual reasoning before generation, improving parsing accuracy on complex prompts.Activation conditions: only applies when not in image-group mode (enable_sequential not true) and without image input (image_urls not provided); ignored otherwise

boolean

default:"false"

Image-group mode (comic strip / storyboard). When enabled:

n cap raises to 12
resolution capped at 2K
thinking_mode and color_palette have no effect

Suited for storyboards, comic strips, and themed e-commerce sets — any “themed group of related images” use case

array

Custom color palette. 3-10 items of {hex, ratio}, with ratio summing to 100%.Activation condition: only applies in non-group mode. See Composite Field Reference

array

Interactive editing bbox list, one-to-one with image_urls, max 2 boxes per image.Only applies when action: "interactive_edit". See Composite Field Reference

Composite Field Reference

`color_palette` — Custom Color Palette

Specifies primary colors and their proportions for the output. The model distributes color coverage in the image based on the given ratios. Structure: array, each item is {hex, ratio}

Field	Type	Description
`hex`	string	Hex color, e.g. `#0A2540`, case-insensitive
`ratio`	number	Percentage coverage in the image. All items must sum to 100

Constraints:

Item count: 3-10
Sum of ratio: strictly 100 (integer percentages)
Only effective in non-group mode (ignored when enable_sequential is true)

Example:

"color_palette": [
  {"hex": "#0A2540", "ratio": 50},
  {"hex": "#F5F5F0", "ratio": 35},
  {"hex": "#E04B3A", "ratio": 15}
]

`bbox_list` — Interactive Editing Boxes

Draw boxes on a reference image to tell the model “edit only inside the box,” leaving the outside unchanged. Exclusive capability of the Wan series for interactive editing. Structure: triple-nested array [[[x1, y1, x2, y2], ...], ...]

Outermost: each item corresponds to one image in image_urls, one-to-one (counts must match)
Middle: multiple boxes on a single image, max 2 boxes per image
Innermost: coordinates of one box, 4 numbers [x1, y1, x2, y2], top-left and bottom-right corners (pixel coordinates)

Constraints:

Only applies when action: "interactive_edit"
Max 2 boxes per image
Coordinates use the reference image’s original pixels

Example (single image, single box):

"image_urls": ["https://cdn.example.com/cat.jpg"],
"bbox_list": [[[120, 80, 540, 460]]]

Example (single image, two boxes):

"image_urls": ["https://cdn.example.com/scene.jpg"],
"bbox_list": [[[100, 100, 400, 400], [500, 200, 800, 500]]]

Example (multiple images, one box each):

"image_urls": [
  "https://cdn.example.com/img-a.jpg",
  "https://cdn.example.com/img-b.jpg"
],
"bbox_list": [
  [[120, 80, 540, 460]],
  [[200, 150, 600, 500]]
]

Resource Limits

Item	Limit
Reference images (`reference`)	2-9
Reference images (`image2image` / `edit` / `interactive_edit`)	1
Single image size	≤ 30MB, supports JPG/PNG/WEBP
Output resolution	`1K` / `2K` / `4K` (group mode caps at `2K`)
Group count `n`	Up to 12 (requires `enable_sequential: true`)
`bbox_list` boxes	Max 2 per image
`color_palette` items	3-10, `ratio` sums to 100%
Output file	JPG URL, valid for 24 hours
