I have comfyUI already installed but the KLEIN_EDIT_ULTRA-MODELS-NODES_INSTALL does absolutely nothing... I run it, press 1 (or 2 or 3 whatever) and nothing happens.

All of his [...]_AUTO_INSTALL.bat files are designed to install exactly where they're run from.. so if you wanted to install it into d:\my_stuff 1. Open your D: drive and create a new folder named my_stuff 2. Drag and drop (or copy and paste) your (whatever-it-is)_AUTO_INSTALL.bat file into that new d:\my_stuff folder. 3. Run it: Double-click the .bat file from inside d:\my_stuff The script will detect its new home and download and install everything right there, inside d:\my_stuff\ComfyUI_windows_portable .

would be nice to get the option to choose where to install it, damn annoying get denied errors all the time cause its in system32 library

For image editing Klein 9B seems fine, but I dont get any better results from it than with ZIB or ZIT. Is it the new "king" because its multimodal? Or what are advantages here? ZIT gets more Styles and has superior LORAs, ZIB can get more creative stuff, ZIT better quality images,... Klein just for editing?

hello some feedback: I was confused by your preview image which shows video motion, and your comaparison to nanobanana (which also does video), but after watching your youtube seems like this workflow does NOT do video. anyways, that threw me for a little loop. thanks for making the content you make. cheers

Will these auto setup work on Simplepod?

I opened ostris AI-toolkit but I didn't see an option for training loras for Klein. Is this something in the works? Or is a different lora trainer needed?

Hi K, thanks for the new Klein workflow. Unfortunately, I am getting a message saying that I have not got the following custom nodes installed: FastFilmGrain and FastLaplacianSharpen I have updated comfyUI to the latest version but I still get the message and Comfy Manager doesn't know anything about them, apparently. So, how should I install these missing nodes?

hey thanks for this, its amazing as usual however... to create an image its taking me 75 seconds, definitely not the 2-4 seconds you suggested, I have a 5070 ti asus so definitely not a PC issue, I ran the auto.bat file to just install the models etc... everything works fine but its just taking way too long to generate an image

Anthony Harris

When I installed the missing nodes onto an current install of ComfyUI, I get some missing customs nodes which I can't find in the nodes manager. Including FastFilmGrain, FastLaplacianSharpen and LayerUtility: ImageRemoveAlpha. Also I updated ComfyUI to the latest version

Z-image has unfortunately fallen short when it comes to training...at least as of right now, everyone is extremely disappointed with its lack of correct training (me included) so much so that a lot of people are moving toward Klein since the model is super ultra versatile and super easy to train, I'll make the next video on that, since I really liked the model. I still really like Z-image, I love that model but when it comes to training, it seems like the community has kinda abandoned working on it until further notice or new breakthrough...

Please, can someone help me? I really don’t understand what I’m doing wrong, even though I’ve been trying for days. I want to create a LoRA of a woman, but it’s extremely difficult to consistently generate the exact same model (fixed seed, fixed base prompt). With Z-image Turbo it’s basically impossible, so I’m using the regular Z-image with the workflow below. Am I doing something wrong, or should I be using a completely different base model instead of Z-image? (I’m about to try Klein Edit next.) Thank you!!
