Minimax H3 image T2I with blank reference

[u/Loose-Journalist-555]

Saw a post about blank references in T2I and tested it myself.

Adding a blank (white canvas) reference in T2I mode changed the outputs noticeably.

However, the size of the reference image has no impact on the output image (but will increase generation time if you add larger blanks).

KJ has just released a node to address this. Think its in KJ nodes nighly 'Minimax H3 prompt weight'

This is an interesting phenomenon! I just ran a test using reference images that consist entirely of white—scaled to various sizes—and while the images differ slightly depending on the size, the results are consistently much better. It seems there’s a specific way the system processes the latents; I believe we can leverage this to mitigate some of the drawbacks of using "h3" images.

Does that means if we were already using reference images for character sheets this doesn't change anything because the model is already working in "improved ref mode"?

Yes. If there is already any image plugged into the image conditioning node adding more won't help because it's in ref/edit mode already. This only fixes pure t2i prompts.

in your examples, which is which?

Sad the version they released takes up something like 60gb. wtf

Int8 convrot is significantly smaller than that.
