Different versions of ZIT require different nodes.
Here are a few versions I use regularly.
All of the following workflows have been tested and confirmed working on ComfyUI 0.8.2.
ZIT Original v1.1

This workflow works for ZIT versions like BF6, FP8
I added a Conditioning Noise Injection node to this workflow to increase ZIT’s output diversity.
By default, this node is turned off — just manually disable its Bypass to enable it.

ZIT AIO v1.1

This workflow works with ZIT’s AIO-FP8 and AIO-BF16 versions.

ZIT GGUF v1.1

This workflow works with the ZIT GGUF version.

ZIT Nunchaku v1

This workflow works with ZIT Nunchaku.
The official ZIT LoRA Loader for Nunchaku hasn’t been released yet, so LoRA isn’t supported in this workflow for now.
I’ll update it once the official LoRA Loader is out.
