Wan 2.7 Image Pro
What is Wan 2.7 Image Pro?
Wan 2.7 Image Pro is the highest-quality image model in Alibaba's Wan line. It exposes the same parameter shape as Wan 2.7 Image (up to nine reference images, thinking mode for text-only runs, seven aspect ratios, 5000-character prompts) and pushes output up to 4K. The model auto-selects between text-to-image and editing based on whether image_urls is set. Use it for print, packaging, OOH, and any final asset where quality matters more than turnaround.
Key features of Wan 2.7 Image Pro
Four features cover what changes versus the standard Wan 2.7 Image.
Up to 4K output
The headline upgrade over the standard Wan 2.7 Image. Same prompt, same references, same seed, higher resolution. Useful for print, packaging, and large-format displays.
Up to 9 reference images
Same nine-reference cap as the standard Wan 2.7 Image. Useful for brand toolkits, character casts, and multi-style alignment in one call.
Thinking mode on text-only runs
`thinking_mode: true` adds a reasoning pass before drawing. On by default. Useful for dense, multi-subject prompts where composition matters.
Editing preserves input aspect ratio
When references are present, output keeps the source aspect ratio. Useful for product retouching and character restyling where the layout must not shift.
Best for
Print and large-format
4K marketing creative, packaging, OOH, and any frame that needs to survive heavy crop and zoom.
Complex briefs
Thinking mode on text-only generations for harder scenes with many elements or subjects.
Brand toolkits
Up to nine references in a single request keeps colour, character, and layout consistent across a series.
Premium stills
Final-quality output when longer renders are acceptable and quality matters more than throughput.
Multi-reference editing

High-detail composition
Highest quality in the Wan image line. Useful when 2K plateaus.
