V3: Solve the saturation problem + has more variated dataset, ill do v4 with more sharpen for images that already are bigger
Made with collaboration with @artificialguybr
this actually upscale compressed and bad looking images, but dont work on blurred image and very pixelated ones.
to upscale more than 1024x1024 as default of qwen, you need to change your workflow to upscale the image in latent before using the lora.
Prompt: upscale this image

This might be the best upscaler I've ever used
So I guess you've never used seedvr2- for low rez, fuzzy and old photos of people, nothing comes close!
More options is better, of course, but really everyone should have seedVR2 as their first go to for difficult upscales. SeedVR2 is notorious for being an impossible to use video upscaler (on local hardware), but for a single frame (ie., an image) it works brilliantly locally.
Sometimes it works great, sometimes it's like "i don't know what you want from me", even when downscaling before upscaling.
Where can you download that? I thought it was paid.
v1 is good, v2 not work well, v3.1 work very good.
did you manage to not having the image changing the angle? my case is a mirror selfie girl, the output give me the image with the person more far away from the mirror se we see bigger angle...
@carlitajohn89931 i think this is the original problem from base model, it extends the image rather than enlarge the image. in a very rare case, it enlarge it.
@takomli2013979 there's the v1 and the v3 the v3 seem to work good for details but the v1 doesn't distort as the v3 or im mistaken here, i've already setted the scaleimagetotalpixel node to 2.00 lanczos or nearest-exact but prefer lanczos and just follow the load image and come right before the vae encode which goes to the latent entry of the ksampler, there's still the perspective distance changes, anyway i think i've found a fix for it but im not sure im gonna keep trying and if it goes well then i'll post preview here also if the author come here and see my message if you have a clue on how to handle that any tips? btw good work, rare to see a lora functioning nowadays
It's amazing!
This works pretty well when upscaling to ~1 megapixels. However, the view/perspective changes when I upscale images to over 1024px. The saturation and contrast of the upscaled images also increase when going over 1 megaxpixels.
I've had pretty good results using v1 first, then using the output image as the input image and running it again through v3.
Belo lora!
edit: I used qwen-image-lighting-4steps-V1-0 with 4 steps, qwen edit 2509 fp8 on both passes. Strength:1 on everything
bro share the upscaler workflow
@arjunharjunh736 it's just a regular ass qwen edit workflow, nothing special. I was manually copying the output from the first pass with v1 then pasting it into the "upload image" node and running the workflow again a second time but with v3 instead of v1. Worked well for some images, but not all
I thought going over 1 mega pixels causes issues with QWEN?
The limit is for generating. Once the generation exist, you can upscale it as usual.
you can go better with latent upscaling, them sampling then again
@luisa_pinguin How do you do this, what is the workflow?
hi can you send a screenshots of the workflow... im really lost right now..
same request, I'd love to see the workflow to achieve the samples please! Thanks
im using the default qwen edit workflow from comfy ui templates, nothing new.
same request, I'd love to see the workflow to achieve the samples please! Thanks
If you can share the workflow, it would help a lot, not everyone is an expert on this site
Amazing LoRA. Has beaten Nano Banana. Enough said.
Share workflow please, i can't make it works : (((
Right click and unpack the nodes in qwen- See the lora? Look what its attached to. Duplicate the lora and add this lora model into it. connect the input of the new lora with the output of the original lora. with the new lora connect the output to where the same output was from the original lora. And thats it. Assuming you downloaded the model then reloaded comfyui this should work fine for you.
face deformation = 10000000000%
send previews of your outputs?
Lora Fantástico. Obrigado mestre :)
Do I use this as a lora or is this a upscaler model? For example do I save it in the lora folder or the upscaler folder in comfy? Does this also change the dimensions of the image, i'm looking to try to make stuff that I can print near poster size
