Pixart Sigma - Like ELLA, but for Low VRAM SDXL+ Resolutions in ComfyUI!

Pixart Sigma was released recently, and while the main repo takes a little tweaking to run nicely on 24GB VRAM, ComfyUI comes to the rescue making it easy to run in just 6 GB!
Like with ELLA, T5 encodings replace CLIP leading to increased prompt adherence. Inthis video I show you how to get going for FREE in ComfyUI, and compare SDXL vs Pixart Sigma.
All this without one of those SD3 “no commercial use” licenses!

Thanks buddy! Especially caught your words that PixArt generates more different faces than SD. These identical smiling cute ladies with almond-shaped features are already starting to get annoying, and it has not even been a year. I have installed PixArt at my place, I'm studying it now, but the first results are impressive.

[@MrSporf]

Wow. I'm impressed. The prompt understanding is something else - quite amazing!

[@steffen_r]

Thx for sharing. The demo looks promising and the model has a good understanding of prompts.

[@zerorusher]

Since Stable diffusion 3 weight will probably never be released (or at least delayed until stability AI has something much better) its very nice to see new open models emerging!

[@user-eq1rf2hq8s]

Ah, so that's why I couldn't load the model in comfy! Thanks - you cleared up where I was going wrong with the custom node install.

[@Digital_Toolbox]

Thanks for the great content! What I wasn't sure about was if I already have comfyui Install up and running, can I just skip the preparation step and move directly to step two? Thanks!

[@Armaan27012012]

do you have a workflow which has pixart and controlnet and ipadapter?

[@WatchNoah]

what linux distro are you using / can recommend?

[@l.x6]

lol the end

[@harshitpruthi4022]

i am trying to do some experiments , will it work with either ipadapter or faceid , have anyone tried it

[@bebeno1]

I wish we could convert any fine-tune sdxl model to T5 encoder like juggernaut that would be amazing

[@fredmcveigh9877]

Hey Nerdy. I respect your opinion and you haven't said anything about SD3. Please let us know what you think of it and the fact it doesn't seem to be open source anymore.

[@LouisGedo]

👋

[@WhatsThisStickyStuff]

This uses SDXL components but isnt actually sdxl right? Like we cant use sdxl control nets or anything

[@JustFor-dq5wc]

This new model is great. Thanks Rodent!

Hoping this comes to forge

[@CapsAdmin]

I'd guess they are samey on sdxl because you are using a community model. I think it would be fair if you used the base model, at least in addition.

I feel super sad when I see something very cool and is Cuda
