ComfyUI-QG-Tools

value

Passes any wire through unchanged and, on the way, unloads ComfyUI's cached models and empties the CUDA cache. Put it between a heavy stage and the next one when the second keeps running out of VRAM. Every release step is best-effort: if a core API is missing or renamed, that step is skipped and the wire still flows. Like any node it only runs when its input changes, so it never breaks caching downstream.
