Alibaba Wan 2.7 Text-to-Image Pro
Alibaba Wan 2.7 Text-to-Image Pro (alibaba/wan-2.7/text-to-image-pro) is the professional tier of Alibaba's WanXiang 2.7 text-to-image generation model, supporting output resolutions up to 4K (4096×4096). Combined with built-in thinking mode for enhanced reasoning, it delivers higher-fidelity compositions ideal for print-ready assets, large-format posters, detailed product visuals, and any workflow where resolution and quality are the priority.
Why it stands out
-
Up to 4K resolution output
Generate images up to 4096×4096 total pixels (512–8192 per dimension)—ideal for print, large-format displays, and high-DPI screens where standard 1024px output falls short. Aspect ratio: 1:8–8:1.
-
Thinking mode for smarter generation
Built-in thinking mode enables the model to reason about prompt intent before generating, producing more coherent compositions and better prompt adherence.
-
Fast, one-shot text-to-image generation
Generate an image in a single run for quick ideation and production workflows.
-
Custom size output
Set output size directly (512–8192 per dimension) to match banners, thumbnails, posters, or social formats. Total pixels must be between 768×768 and 4096×4096, with aspect ratio between 1:8 and 8:1.
-
Seeded iteration
Use a fixed seed to refine style and layout with more repeatable variations.
Parameters
| Parameter | Description |
|---|
| prompt* | Text description of the image you want to generate. |
| size | Output size in pixels (widthheight). Range: 512–8192 per dimension. Default: 10241024. Total pixels: 768×768–4096×4096. Aspect ratio: 1:8–8:1. |
| thinking_mode | Enable thinking mode for enhanced reasoning and better image quality (default: true). Increases generation time. |
| seed | Set a fixed seed for more repeatable iterations (-1 for random). |
How to use
- Write a clear prompt (subject + setting + style).
- Choose a size that matches your target aspect ratio and resolution needs (e.g. 20482048, 40962048 for ultra-wide, 2048*4096 for tall posters).
- Leave thinking_mode enabled (default) for best quality, or disable it for faster generation.
- Set a seed if you want repeatable iterations (keep the same seed while you tweak the prompt).
- Click Run, review the result, and iterate.
Prompt tips
- Start with subject + environment + style:
"A modern tea shop interior, warm afternoon light, minimalist wood design, cinematic photography."
- Add camera / composition when framing matters:
"wide shot, shallow depth of field, 35mm film look."
- Keep instructions positive and specific (what you want to see, not what you fear).
- With thinking mode enabled, the model handles short or ambiguous prompts better—but detailed prompts still yield the best results.
- For 4K outputs, include fine detail cues (textures, materials, lighting) to take full advantage of the higher resolution.
Pricing
- $0.075 per generated image
Notes
- Output size is 512–8192 pixels per dimension. Total pixels must be between 768×768 and 4096×4096, with aspect ratio between 1:8 and 8:1.
- Thinking mode is enabled by default and improves quality, but adds some latency. Disable it if speed is the priority.
- Higher resolutions (e.g. 4096×4096) will take longer to generate than standard sizes.
- Returned image URLs may be time-limited—save outputs if you need long-term storage.
