# WAS Node Suite weights
|
| 18 |
+
|
| 19 |
+
The model files [WAS Node Suite](https://github.com/WASasquatch/was-node-suite-comfyui) runs in
|
| 20 |
+
ComfyUI, kept in one place so a node does not break when a third-party copy is moved or removed.
|
| 21 |
+
Some are upstream checkpoints byte for byte, some are converted to safetensors, and the model
|
| 22 |
+
families under `models/` are ComfyUI conversions and quantisations of upstream releases. Nothing
|
| 23 |
+
here is trained by this project. Every file keeps the licence of the work it came from, listed
|
| 24 |
+
beside it below; the Kandinsky 6 audio VAE and the BluePixel transformers are for
|
| 25 |
+
non-commercial use only.
|

| 37 |
+
With `features.network: true` in WAS Node Suite's `config.yaml`, the pack fetches a file from
|
| 38 |
+
every folder outside `models/` the first time a node needs it. The `models/` folders are laid out as
|
| 39 |
+
ComfyUI's own `models` folder: each subfolder goes into the matching folder under
|
| 40 |
+
`ComfyUI/models`, downloaded by hand.
