Nodes and Workflows

What are Nodes?

A Node is simply a single operation that takes in inputs and returns outputs. Multiple nodes can be linked together to create more complex functionality. All InvokeAI features are added through nodes.

With nodes, you can easily extend the image generation capabilities of InvokeAI and build workflows that suit your specific needs.

Anatomy of a Node

Individual nodes are made up of the following:

Inputs

Edge points on the left side of the node window where you connect outputs from other nodes.

Outputs

Edge points on the right side of the node window where you connect to inputs on other nodes.
