A node is a single unit of work in a workflow. It takes inputs, does something with them (load a model, encode a prompt, sample, save an image), and passes its outputs to the next node. Workflows are built by connecting nodes together.

Core nodes

Built-in nodes maintained by the Comfy Org team. They ship with every ComfyUI install and run on your own hardware.
