>any reason to use Wan specifically for the upscale? And why not just use Wan completely for the initial t2i,
I like the skin/detail of Wan at higher resolutions compared to the (albeit limited) testing I did with Qwen upscaling.
As for directly doing t2i with Wan, prompt adherence is worse and it sometimes produces some real bodyhorror, had to cherrypick some gens for this comparison. It also adds backgrounds without being prompted for them, this can be both a blessing and a curse for both models. With Qwen you have to be careful to actually include enough detail in the prompt, it won't really implicitly add stuff to the image. Wan will just do whatever.
Comparison is: Bare Qwen - Qwen with Wan upscaling - Wan with Wan upscaling
