Generate AI Videos on Your Own GPU — WAN 2.1 + ComfyUI, Pre-Configured

AI video generation models like WAN 2.1 are open-source and free to run. The actual barrier is setup — downloading 14 billion parameter model weights, installing ComfyUI, configuring custom nodes, resolving dependency conflicts, and ensuring the correct workflow templates are in place. On a fresh VM, this takes hours.

We built two pre-configured VM images that skip the entire process. Every model, every custom node, and every workflow template is already installed. You deploy the VM, open your browser, load a template, and generate video.

This guide covers both images: one for text-to-video, and one that adds image-to-video on top of it.
