Workflow

This is a slightly cleaned-up version of KJ's workflow.

---------------------

ComfyUI Backend Update Required

This workflow requires KJ’s Bernini PR version of the ComfyUI backend.

It may not work on the current stable ComfyUI backend yet.

I recommend testing this in a copied portable ComfyUI folder instead of overwriting your main working ComfyUI installation.

---------------------

Advanced Manual Update Method

If you are comfortable with CLI commands, run the following inside your ComfyUI folder:

cd /d "YOUR_COMFYUI_FOLDER_PATH"

git remote add kijai https://github.com/kijai/ComfyUI.git

git fetch kijai bernini

git checkout -B deno-bernini-preview kijai/bernini

Then update the Python dependencies in your ComfyUI Python environment.

Portable example:

..\python_embeded\python.exe -m pip install -r requirements.txt

If you are not comfortable with manual CLI updates, use the Easy Update BAT method below.

---------------------

Easy Update.bat

Easy Update BAT Method for Portable/Test ComfyUI

I prepared an Easy Update BAT file for quick testing with a portable ComfyUI folder.

Note: If you do not feel this file is safe, please do not use it. Use the manual installation method instead.

1. Copy your existing ComfyUI folder and make a separate test folder.

2. Inside the copied folder, find the ComfyUI folder that contains main.py.

3. Place DENO_Bernini_Preview_Backend_Update.bat in the same folder as main.py.

The folder should look like this:

ComfyUI
├─ main.py
├─ DENO_Bernini_Preview_Backend_Update.bat
├─ models
├─ custom_nodes
└─ ...

4. If ComfyUI is running, close it first.

5. Double-click DENO_Bernini_Preview_Backend_Update.bat.

6. When the black console window asks:

Type YES to update this TEST ComfyUI folder:

Type:

YES

Then press Enter.

7. When you see DONE, the backend update is complete.

8. Start ComfyUI again using your usual ComfyUI launch BAT file.

---------------------

Workflow Setup

1. Update the ComfyUI backend first using one of the methods above.

2. Download my Bernini workflow and open it in ComfyUI.

3. Install the required custom nodes.

You may need:

- Deno Custom Nodes v0.7.27 or newer
- ComfyUI-KJNodes
- Video Helper Suite
- rgthree-comfy
- ComfyUI-GGUF, only if your workflow uses GGUF models

If ComfyUI shows Missing Custom Nodes, use ComfyUI Manager’s Install Missing Custom Nodes feature.

4. Update Deno Custom Nodes.

In ComfyUI Manager, update deno-custom-nodes.

Version v0.7.27 or newer is required.

5. Download the required models.

Inside the workflow, use the (Deno) Easy Model Download Helper node.

It shows the required model links and the correct target folders.

Download the models and place them in the paths shown by the helper node.

6. Fully restart ComfyUI.

7. Run the workflow.

---------------------

Important Notes

This is a preview/testing workflow for trying Bernini before the backend is officially merged into stable ComfyUI.

I recommend using a copied portable ComfyUI test folder first, not your main production ComfyUI installation.

The update BAT only updates the ComfyUI backend code to the Bernini preview branch.

It does not change your port, launch BAT files, model paths, or PyTorch/CUDA setup.

---------------------

It doesn’t look perfect yet, but I’m really excited for future Bernini updates.
