Over the last few days, NVIDIA released an incredible new 4K upscaling model called PixelID. The results are genuinely impressive: outstanding detail, excellent identity preservation, and extremely fast performance. It can even run on GPUs with as little as 4GB of VRAM and upscale a 1K image to 4K in just a few seconds.

So far, it has received excellent benchmark scores and, in my opinion, it's currently the best upscaling model available.

I'll be sharing the original workflow with you, but while testing it I found a few limitations. That's why I built a custom workflow to solve those issues, which you can see in the preview images. I'll be uploading it very soon.

Default workflow for 1024 and 512 input images :

One of PixelID's main weaknesses is that it struggles with very small or extremely low-quality images. But in our community, "impossible" isn't an option. We always find a way.

To overcome this, I designed a workflow that combines Qwen, Flux Klein, and PixelID together, allowing you to upscale even the smallest and lowest-quality images while maintaining excellent quality and consistency by just a one click!

Stay tuned.

We're getting back to our normal pace, just like before. 🚀
