Stable Version and Nightly Version

When you update, you can choose which version to install.

Version Features Recommended Case
Stable Version A finalized release with noticeable bugs fixed, confirmed to work. Official announcements usually refer to this version. When you want to prioritize stability.
Nightly Version The latest version, with every newly added feature and fix. It hasn't been fully tested, so you may run into bugs. When you want to try new features or support for the latest models immediately.

If you "updated to the latest version but still can't use this feature/model," you may have chosen the Stable Version. The latest features go into the Nightly Version first.

Portable Version

The Windows portable version is easy to update: just run one of the included .bat files.

Run a .bat file in the folder below to start the update. Even if it looks stuck while running, it's usually still working, so wait until Done! appears.

  • update_comfyui.bat
    • Updates to the Nightly version.
  • update_comfyui_stable.bat
    • Updates to the Stable version.
  • update_comfyui_and_python_dependencies.bat ⚠️
    • Updates to the Nightly version, then also updates PyTorch (a core Python library).
    • Updating PyTorch is very likely to break custom nodes, so if nothing is wrong right now, it's better not to use this one.

Manual Installation Version

Update to Nightly Version

Run the following commands to update to the latest Nightly version.

Windows

# 1. Activate virtual environment
.\venv\Scripts\activate

# 2. Update ComfyUI core with Git
git pull --ff-only

# 3. Update necessary Python libraries
pip install -r requirements.txt

Mac / Linux

# 1. Activate virtual environment
source venv/bin/activate

# 2. Update ComfyUI core with Git
git pull --ff-only

# 3. Update necessary Python libraries
pip install -r requirements.txt

Switching to Stable Version

Switching the current Git HEAD to the latest stable tag takes some fiddly steps. If you want the stable version on a manual install, it's usually easier to clone the Stable branch from the start or to use Manager.

ComfyUI Manager

If you have ComfyUI Manager installed, you can update from the UI.

ComfyUI_Manager_Updates
ComfyUI_Manager_Updates
  • 1. Select the version you want to update to (Nightly Version or Stable Version)
  • 2. Click the Update ComfyUI button

Update All is a button to update all installed custom nodes, not ComfyUI itself.

Desktop Version

It updates automatically.

As a rule, it only runs the stable version, so if you want the latest features, use something like the Portable version.
