ComfyUI node graph (12)#

The executable ComfyUI prompt graph: 12 nodes across 10 distinct node classes, wired by 17 data dependencies. Nodes tinted green come from a custom node pack this workflow declares; the rest are ComfyUI core / baked-community classes.

Models & dependencies#

Custom node packs (2)#

The non-core ComfyUI node classes this graph requires; the RunPod worker image the workflow runs on must bake or install a pack that provides every one of them.
