[Config file](extra_model_paths.yaml.example) to set the search paths for models. Workflow examples can be found on the [Examples page](https://comfyanonymous.github.io/ComfyUI_examples/) ## Release Process ComfyUI follows a weekly release cycle targeting Monday but this regularly changes because of model releases or large changes to the codebase. There are three interconnected repositories: 1. **[ComfyUI Core](https://github.com/comfyanonymous/ComfyUI)** - Releases a new stable version (e.g., v0.7.0) roughly every week. - Starting from v0.4.0 patch versions will be used for fixes backported onto the current stable release. - Minor versions will be used for releases off the master branch. - Patch versions may still be used for releases on the master branch in cases where a backport would not make sense. - Commits outside of the stable release tags may be very unstable and break many custom nodes. - Serves as the foundation for the desktop release 2. **[ComfyUI Desktop](https://github.com/Comfy-Org/desktop)** - Builds a new release using the latest stable core version 3. **[ComfyUI Frontend](https://github.com/Comfy-Org/ComfyUI_frontend)** - Every 2+ weeks frontend updates are merged into the core repository - Features are frozen for the upcoming core release - Development continues for the next release cycle ## Shortcuts | Keybind | Explanation | |------------------------------------|--------------------------------------------------------------------------------------------------------------------| | `Ctrl` + `Enter` | Queue up current graph for generation | | `Ctrl` + `Shift` + `Enter` | Queue up current graph as first for generation | | `Ctrl` + `Alt` + `Enter` | Cancel current generation | | `Ctrl` + `Z`/`Ctrl` + `Y` | Undo/Redo | | `Ctrl` + `S` | Save workflow | | `Ctrl` + `O` | Load workflow | | `Ctrl` + `A` | Select all nodes | | `Alt `+ `C` | Collapse/uncollapse selected nodes | | `Ctrl` + `M` | Mute/unmute selected nodes | | `Ctrl` + `B` | Bypass selected nodes (acts like the node was removed from the graph and the wires reconnected through) | | `Delete`/`Backspace` | Delete selected nodes | | `Ctrl` + `Backspace` | Delete the current graph | | `Space` | Move the canvas around when held and moving the cursor | | `Ctrl`/`Shift` + `Click` | Add clicked node to selection | | `Ctrl` + `C`/`Ctrl` + `V` | Copy and paste selected nodes (without maintaining connections to outputs of unselected nodes) | | `Ctrl` + `C`/`Ctrl` + `Shift` + `V` | Copy and paste selected nodes (maintaining connections from outputs of unselected nodes to inputs of pasted nodes) | | `Shift` + `Drag` | Move multiple selected nodes at the same time | | `Ctrl` + `D` | Load default graph | | `Alt` + `+` | Canvas Zoom in | | `Alt` + `-` | Canvas Zoom out | | `Ctrl` + `Shift` + LMB + Vertical drag | Canvas Zoom in/out | | `P` | Pin/Unpin selected nodes | | `Ctrl` + `G` | Group selected nodes | | `Q` | Toggle visibility of the queue | | `H` | Toggle visibility of history | | `R` | Refresh graph | | `F` | Show/Hide menu | | `.` | Fit view to selection (Whole graph when nothing is selected) | | Double-Click LMB | Open node quick search palette | | `Shift` + Drag | Move multiple wires at once | | `Ctrl` + `Alt` + LMB | Disconnect all wires from clicked slot | `Ctrl` can also be replaced with `Cmd` instead for macOS users # Installing ## Windows Portable There is a portable standalone build for Windows that should work for running on Nvidia GPUs or for running on your CPU only on the [releases page](https://github.com/comfyanonymous/ComfyUI/releases). ### [Direct link to download](https://github.com/comfyanonymous/ComfyUI/releases/latest/download/ComfyUI_windows_portable_nvidia.7z) Simply download, extract with [7-Zip](https://7-zip.org) or with the windows explorer on recent windows versions and run. For smaller models you normally only need to put the checkpoints (the huge ckpt/safetensors files) in: ComfyUI\models\checkpoints but many of the larger models have multiple files. Make sure to follow the instructions to know which subfolder to put them in ComfyUI\models\ If you have trouble extracting it, right click the file -> properties -> unblock The portable above currently comes with python 3.13 and pytorch cuda 13.0. Update your Nvidia drivers if it doesn't start. #### Alternative Downloads: [Experimental portable for AMD GPUs](https://github.com/comfyanonymous/ComfyUI/releases/latest/download/ComfyUI_windows_portable_amd.7z) [Portable with pytorch cuda 12.6 and python 3.12](https://github.com/comfyanonymous/ComfyUI/releases/latest/download/ComfyUI_windows_portable_nvidia_cu126.7z) (Supports Nvidia 10 series and...
