ComfyUI-Unload-Model
For unloading a model or all models, using the memory management that is already present in ComfyUI. Copied from https://github.com/willblaschko/ComfyUI-Unload-Models but without the unnecessary extra stuff.
How to install: Clone this repo into the custom_nodes folder, then restart ComfyUI.
How to use: Add in the middle of a workflow to unload a model at that step. Use any value for the value field and the model you want to unload for the model field, then route the output of the node to wherever you would have routed the input value.
For example, if you want to unload the CLIP models to save VRAM while using Flux, add this node after the ClipTextEncode or ClipTextEncodeFlux node, using the conditioning for the value field, and using the CLIP model for the model field, then route the output to wherever you would send the conditioning, e.g. FluxGuidance or BasicGuider.
