Wan 2.6 Image
What is Wan 2.6 Image?
Wan 2.6 Image is the four-reference upgrade in Alibaba's Wan image line. The model auto-selects between text-to-image and editing/style-transfer based on whether image_urls is present. One to four references, seven aspect ratios, prompt extend on by default, and seed control. Prompts cap at 2000 characters and negative prompts at 500. Use it when three references on Wan 2.5 Image is too few but you do not need the nine-reference cap or the 2K/4K output of Wan 2.7 Image.

Zero to four. Omit image_urls for plain text-to-image. Pass 1–4 image URLs for editing or style-transfer runs.
No. The model auto-selects text-to-image when image_urls is empty and editing/style-transfer when it is set. Same model ID for both paths.
Negative prompts list content to suppress. Prompt extend rewrites the main prompt for clarity. They work together: exclusions stay explicit while the positive prompt expands.
Move to Wan 2.7 Image when you need up to nine references, thinking mode, and 2K output. Move to Wan 2.7 Image Pro when you need 4K. Stay on Wan 2.6 Image when four references is enough.
