note: there is a bug on civitai where you cannot see total number of downloads or likes. trust me its getting downloaded. comments are also not appearing for some reason. comment on my youtube video if you have any issues/questions.MY PC SPECS (for comparison):(RTX 3070+I-7) 8gb VRAM + 16gb System RAM = 24gb in total. it works pretty well for such high memory requirements.

(there is a PR pull missing from the GGUF nodes at the moment and until it is merged fully the node wont work without updating it in your command prompt yourself. i dont suggest as it is highly unusable. trust me, use the Vantage node.)TO GET THE VANTAGE NODES, open a command prompt in your custom nodes folder and copy in this command and hit enter: git clone <a target="_blank" rel="ugc" href="https://github.com/vantagewithai/Vantage-Nodes.git">https://github.com/vantagewithai/Vantage-Nodes.git</a>(i removed the "cd comfyui/custom_nodes" portion from the youtube video tutorial as its not needed)use this command once its finished: cd Vantage-Nodes pip install -r requirements.txt this installs the nodes fully. restart comfyui and you drag in my workflow and you have a fully functioning LTX-2 workflow! I HIGHLY RECOMMEND UPDATING YOUR BAT FILE WITH THESE FLAGS: --lowvram --disable-xformers --use-pytorch-cross-attention --reserve-vram 2 --disable-smart-memorythis workflow is very resource intense. even for the lowest quant my pc struggled until i lowered resolution to 480p. i suggest editing your bat file in notepad and just adding the flags to the code line that contains the "--windows-standalone" code and just save the file as a copy and use that one for LTX-2 ONLY. (rename it that if it helps you remember) instructions on how to do it are in the youtube video if you dont know how!TUTORIAL VIDEO<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/OIq1Z25tL3I?rel=1" start="0"></iframe></div>
