ComfyUI Ultimate Upscaler Workflow - Magnific.ai Alternative

Looks like we have it and its by a @Fictions-ai (Thibaud Zamora) who released a ComfyUI Upscaler Workflow that hallucinates and creates highly detailed upscaled images using your own instance of ComfyUI and your own hardware (if you have it) or you use cloud GPU.

What I use:

Hey this is pretty good! Definitely a viable free alternative. Took me about 7 mins on a 3080 but the results are pretty impressive. Going to mess around with settings and prompts a bit more.

Hi could you please tell me how to fix this:

Prompt outputs failed validation
Text Concatenate:
- Value not in list: clean_whitespace: '' not in ['true', 'false']
Text Concatenate:
- Value not in list: clean_whitespace: '' not in ['true', 'false']

Error occurred when executing CLIPTextEncodeSDXL:

'g'

This is not that good imo, i can do this simply using img2img and ultimate upscale, no need for all these nodes nd "workflow". why dont you compare it with magnific nd see if it even comes any close to be a magnific alterative.

For some reasons for me doesn't work, everything it's in place I don't see missing nodes i receive this error in the terminal:
got prompt

ERROR:root:Failed to validate prompt for output 180:
ERROR:root:* Text Concatenate 63:

Prompt executor has been patched by Job Iterator!
Prompt executed in 4.13 seconds
and i see read circle around the text concatenate nodes (both)

when i queue prompt i get this message in cmd: UserWarning: 1Torch was not compiled with flash attention how do i fix it?

Washed colours fixed in the Workflow v4, just amazing results. I recommend to upscale with two min-max values (0.2 - 0.4) and make in Photoshop a masking work with the best of each image.

[雪鷹魚英語培訓的領航]

Thanks. $40 is way too pricey for a few hundred renders.

[alexpolymath]

sorry, I didn't got how exactly on how to set up workflow. I have ComfyUI running on runpod.
Documentation in blog post and github is not straightforward

I don't know if it's me, but I guess SDXL decreases the details(aka blurs) of images generated in SD 1.5. Would this workflow work with SD 1.5 models like Realistic Vision?

[Atractiondj]

how use this? you can make a full step process? i download and instal all, i click to start and i get only image in preview without changes

[Tahar]

How to create a sharper image? Also, there is a problem, it adds defects to the skin, like burned skars

[WasifKhanGD]

Love you man so much for sharing this. Hats off to you buddy!

[ZenithPhoto]

Hello, thanks for this workflow !! can you explain if it possible to upscaler in x4 ?
i had try with use the upscaler 8x NMKD-Superscale_150000_G but the result is not very good... thanks

[Blackkspot]

🤷‍♂️why didn`t you go thru the workflow then? Whats the point of the video?

[bordignonjunior]

could you please share the .json workflow?

[glibsonoran]

I used it (upscale v3), it does add detail that's for sure. It also desaturates the colors and washes out some of the contrast. In some images that's not a problem, but in others it makes the picture less dramatic.

[fabiotgarcia]

Hi there! I didn´t find the workflow on the link you provided. Could you please share your workflow?

[ryokakizaki]

hmm, I can't find the Upscaler .json in the repository, where is it?

[Ethan_Fel]

Ultimate Upscale ruins the colors of the upscale, it's quite visible. Tiled diffusion does it better (color fidelity at super high resolution) but (sadly) it's only working on A1111

[djivanoff]

how long does it take you to process the image?
