## **run it straight (no installation needed way)**

### **workflow**
|
67 |
- example workflow for [gguf](https://huggingface.co/calcuis/ltxv-gguf/blob/main/workflow-ltxv-gguf.json) (see demo above)
|

### **review**
|
71 |
- q2_k is super fast but not usable; keep it for testing only
|
72 |
+
- gguf-node is available (see [here](https://github.com/calcuis/gguf)) for running the new features (the point below doesn't relate to the model)
|
73 |
+
- you are able to make your own fp8_e4m3fn scaled safetensors and/or convert it to gguf with the new node via comfyui
|
74 |
