Nunchaku Multi_input+LoraNow includes two separate workflows: ------Kontext_gguf&amp;safetensors__Multi_input&amp;Lora.json ------Kontext_nunchaku_Multi_input&amp;Lora.jsonAnyone Installed mit-han-lab/ComfyUI-nunchaku but can't get it workin' right? Look here!so I really took my time setting up this workflow this time around. For anyone who's used the official nodes but doesn't know how to use multiple image inputs, or how to customize the generation resolution, or how to switch to the nunchuka-textencoder model… this streamlined workflow is perfect for you!The image generation time using nunchak's int4 model is now, like, one-fourth of what it used to be for me, and with very little loss in quality. I honestly don't even want to use gguf anymore.Nuchaku Checkpoint:<a target="_blank" rel="ugc" href="https://huggingface.co/mit-han-lab/nunchaku-flux.1-kontext-dev/tree/main">https://huggingface.co/mit-han-lab/nunchaku-flux.1-kontext-dev/tree/main</a>aqw-int4-flux.1-t5xxl (Optional):<a target="_blank" rel="ugc" href="https://huggingface.co/mit-han-lab/nunchaku-t5/tree/main">https://huggingface.co/mit-han-lab/nunchaku-t5/tree/main</a> Nunchaku comfyui node:<a target="_blank" rel="ugc" href="https://github.com/mit-han-lab/ComfyUI-nunchaku">https://github.com/mit-han-lab/ComfyUI-nunchaku</a> <a target="_blank" rel="ugc" href="https://github.com/mit-han-lab/ComfyUI-nunchaku">ComfyUI-nunchaku </a>Installation Guide (windows)：1.In the address bar of the <code>ComfyUI_windows_portable</code> directory, type <code>cmd</code> and press enter. Then, enter the following commands to check your torch and python versions:<ul><li><code>"python_embeded\python.exe"</code></li><li><code>"python_embeded\python.exe -m pip list"</code> For example, mine shows python 3.12 and torch 2.5.1+cu124.</li></ul>2.You can install the nunchaku node (ComfyUI-nunchaku v0.3.3) using ComfyUI-Manager, or manually by typing <code>cmd</code> in the address bar of the <code>ComfyUI_windows_portable\ComfyUI\custom_nodes</code> directory and then running <code>git clone https://github.com/mit-han-lab/ComfyUI-nunchaku.git</code>.3.Download the nunchaku whl file that corresponds to your versions from: <code>https://github.com/mit-han-lab/nunchaku/releases</code>. I already checked the version info in step 1, so I'll download <code>nunchaku-0.3.1+torch2.5-cp312-cp312-win_amd64.whl</code>. Afterdownloading, place the whl file in the <code>ComfyUI_windows_portable</code> directory, and then install it using <code>"python_embeded\python.exe -m pip install nunchaku-0.3.1+torch2.5-cp312-cp312-win_amd64.whl"</code>.4.After installing, don't forget to update ComfyUI to the latest version and restart. Also, remember to place the downloaded nunchaku model in the <code>diffusion_models</code> folder. For Nvidia 40-series cards and below, choose <code>int4</code>; for 50-series, you can choose <code>FP4</code>.5.I found that python 3.11-based ComfyUI didn't work properly in my tests, but i'm not completely sure about that.<hr />gguf+LoraGot questions like 'Is there too much going on in the workflow?' or 'Are the hardware requirements too steep?' or 'Where do I even download the models?' or 'Does the output keep ignoring my input image?This workflow is actually made for beginners. You seriously just need this single workflow file, and that's it. And honestly, I barely did anything on it; I just took the official ComfyUI workflow, tweaked it a little, and added support for gguf and Lora. How to Use:1. Drag the workflow or example image into ComfyUI, and install any missing nodes.2. Download the model, place it in the <code>diffusion_models</code> folder, then update ComfyUI and restart.

Change image style / Style transfer.2. Add or remove objects in the image.3. Make characters perform different actions (like turning around) or change their expressions while keeping their look consistent.4. Combine multiple characters and scenes.5. Virtual try-on for models. (<s>I haven't gotten this to work in my tests yet.</s> It worked, but I'm not happy with the results. ~The good news is that it is open source and free) so if you're selling clothes, check this out for model try-ons: if you don't specify a particular model, just give it the images of the clothes, and let Kontext generate the model for you. You'll actually get much better results that way!
