FLUX2 memory with and without images

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

less ram usage while no use of input images

### Actual Behavior

more ram usage while using no input images

### Steps to Reproduce

use the actual workflow for flux2 from comfy
use a gguf model Q4
attach input images - watch vram usage ~14-15GB
disable images vram usage >16GB

### Debug Logs

```powershell
no logs, is no error message
```

### Other

_No response_

Start by reproducing the actual FLUX2 ComfyUI workflow with a GGUF Q4 model, comparing VRAM usage with input images attached and disabled. Check whether the difference is reproducible without custom nodes; done should identify the cause of the higher no-image usage and confirm a measured reduction without changing expected workflow behavior.
