This uses the newest model Omnigen released just a few days ago: <a target="_blank" rel="ugc" href="https://github.com/VectorSpaceLab/OmniGen">https://github.com/VectorSpaceLab/OmniGen</a> Be sure to update your nodes since the last version, since the nodes have been completely overhauled through my commits. You can now change the model, use FP8 models, and more!<h2 id="how-to-install:-5sdh7l755">How to Install:</h2>The model files are no longer automatically downloaded, since you can use any model you want now that is compatible, including FP8 models. <ol><li>Create an OmniGen folder the models directory in /ComfyUI/models/Omnigen (this has moved from the older folder location)</li><li>If you've already downloaded it before and want to use BF16, move the model folder from \ComfyUI\models\AIFSH\Shitao\OmniGen-v1 to \ComfyUI\models\OmniGen\OmniGen-v1</li><li>If you don't have the model files yet and want to use BF16, within the \ComfyUI\models\OmniGen download all of the files from <a target="_blank" rel="ugc" href="https://huggingface.co/Shitao/OmniGen-v1">https://huggingface.co/Shitao/OmniGen-v1</a> into its own folder.You can also download the models with GIT.First do git LFS and afterwards do git clone <a target="_blank" rel="ugc" href="https://huggingface.co/Shitao/OmniGen-v1">https://huggingface.co/Shitao/OmniGen-v1</a>.</li><li>Or optionally download the FP8 version using the same method as above, but instead for that repo: <a target="_blank" rel="ugc" href="https://huggingface.co/silveroxides/OmniGen-V1-fp8_e4m3fn">https://huggingface.co/silveroxides/OmniGen-V1-fp8_e4m3fn</a> First do git LFS and afterwards do git clone <a target="_blank" rel="ugc" href="https://huggingface.co/silveroxides/OmniGen-V1-fp8_e4m3fn">https://huggingface.co/silveroxides/OmniGen-V1-fp8_e4m3fn</a> .This can take awhile, and may appear as if it is doing nothing for a bit.</li><li>Import workflow and install missing nodes with Comfy Manager!</li></ol> Check out this video to see everything that is possible (while ignoring the installation instructions):<div data-youtube-video><iframe width="640" height="480" allowfullscreen="true" autoplay="false" disablekbcontrols="false" enableiframeapi="false" endtime="0" ivloadpolicy="0" loop="false" modestbranding="false" origin playlist src="https://www.youtube.com/embed/PCL9SAlHqzw" start="0"></iframe></div> It uses a lot of nodes to automate as much as possible. All of them are available via Comfy Manager however. Enjoy!
