Unable to Free Up Memory in a ComfyUI workflow

### Expected Behavior

I am currently working on a workflow in ComfyUI that involves loading large models, such as FluxDev. The workflow performs generation tasks where the output of one model serves as the input for another. However, I encounter an issue when attempting to load a third model; my system's memory (not VRAM) becomes fully utilized.

I would like to know if there is a way to clear memory and unload models that I no longer need within the same workflow. I have 64 GB of RAM, yet loading just the FluxDev model consumes 16 GB of it.

### Actual Behavior

System crashes when loading couple of big models because of RAM filling up

### Steps to Reproduce

load more than 3 big model like flux dev

### Debug Logs

```powershell
system crashes of closes comfiUI
```
