Qwen Wan T2I 2K Upscale

This workflow extends the prompt adherence of Wan 2.2 by using qwen in the first stage at a low resolution. Brings remarkably good detail to low resolution outputs.

Hardware: RTX 3090 24GB

Models : Qwen Q4 GGUF + Wan 2.2 Low GGUF

Elapsed Time E2E (2k Upscale) : 300s cold start, 80-130s (0.5MP - 1MP)

Main Takeaway - Qwen Latents are compatible with Wan 2.2 Sampler

There are two stages:

1stage: (42s-77s). Qwen sampling at 0.75/1.0/1.5MP

2stage: (~110s): Wan 2.2 4 step

1st stage can go to VERY low resolutions. Haven't test 512x512 YET but 0.75MP works

* Text - text gets lost at 1.5 upscale , appears to be restored with 2.0x upscale. I've included a prompt from the Comfy Qwen blog

* Landscapes (Not tested)

* Cityscapes (Not tested)

Interiors (untested)

* Portraits - Closeups Not great (male older subjects fare better). Okay with full body, mid length. Ironically use 0.75 MP to smooth out features. It's obsessed with freckles. Avoid.
