Wan 2.7 Image Pro is the higher tier of Alibaba's April 2026 Wan 2.7 Image family and uses the same parameters as the standard version. The difference is resolution: text-to-image goes up to 4K, while editing with reference images stays capped at 2K. Everything else carries over: up to 9 reference images, up to 4 images per request, 7 aspect ratios, an optional negative prompt and seed, and prompts up to 5,000 characters. Region edits, color palettes and 12-image group series are not available in Jantaris yet.

Best for

  • 4K key art and print visuals generated from text
  • Large backgrounds for video, web and presentations
  • Final renders of prompts drafted at 1K with a fixed seed
  • Detailed edits where the standard tier falls short

Prompting tips

  • 4K works only for plain text-to-image, without image_urls.
  • The default resolution is 2k, so set resolution: 4k explicitly for the largest output.
  • Prototype prompts on Wan 2.7 Image, then render finals on Pro.
  • Describe small detail you want visible at 4K, such as fabric texture or signage.
