Overview
Use the following sequence to establish a working local environment:
- Download the ComfyUI portable archive for the operating system.
- Extract the archive to a convenient location. The extracted directory can be placed on the desktop or another local folder.
- Start the application with the batch file that matches the hardware.
- Confirm that the interface opens. A checkpoint-related error at this stage indicates that the interface is running but no model is available.
- Select a checkpoint by examining its intended visual style and example outputs.
- Download the SafeTensors checkpoint file.
- Place it in ComfyUI/models/checkpoints.
- Restart ComfyUI and select the checkpoint in the Load Checkpoint node.
- Enter a minimal positive prompt and negative prompt, then queue a generation to verify that the entire installation works.
The model-hosting catalog can contain substantial not-safe-for-work content. Filters should therefore be enabled when browsing it in a workplace or shared environment.
