Frequently Asked Questions about ComfyUI
What is ComfyUI?▾
ComfyUI is a node-based visual interface for building and running generative image pipelines locally, letting you compose and tweak model inference workflows with a drag-and-drop graph editor.
How do I install ComfyUI?▾
Download or clone the project from the official site or repository and follow the installation guide; typical steps are installing a compatible Python runtime, required dependencies, placing model files, and launching the UI server or app.
What are the system requirements?▾
A dedicated GPU is recommended for practical performance (typical projects expect ~6–8+ GB VRAM for common models), though CPU-only runs are possible but much slower; ensure you have appropriate drivers and CUDA/ROCm support when using a GPU.
How do I add model checkpoints or weights?▾
Place your model files in the designated models or checkpoints directory or use the UI's model manager if available, then refresh or restart the app to have them appear in the node library for use in pipelines.
Can I run ComfyUI on a CPU-only machine?▾
Yes — ComfyUI can run on CPU-only systems, but expect significantly longer render times and higher memory usage compared with GPU acceleration.
How do I create, save, and reuse workflows or node graphs?▾
Build pipelines in the node editor and use the save/export feature to store graphs as project files or JSON, which you can later import or share to reproduce or modify workflows.
How do I export images or batches from ComfyUI?▾
Use an output or save node in your pipeline to render and write images to disk; most setups support common formats like PNG/JPEG and batch rendering via loop or batch nodes.
Can I extend ComfyUI with custom nodes or plugins?▾
Yes — many node-based UIs support third-party nodes or plugins; check the documentation for the plugin API and installation procedure, place custom node code in the appropriate folder, and restart the app to load them.
What should I do if ComfyUI crashes or can't access my GPU?▾
Check the application logs for error messages, verify that your GPU drivers and CUDA/ROCm toolkit match the requirements, ensure dependencies are installed, and try running a minimal example; if problems persist, collect logs and seek help from the project's support channels.
Where can I find documentation, examples, and community support?▾
Start with the official project website and repository README for setup instructions and docs, then look for examples, issue tracker, and community channels (forums, Discord, or Git) linked from the project's site for additional help and shared workflows.
