# Nodes

> Unified reference for core node categories in Noxus

## What are Nodes?

Nodes are the building blocks of flows. Each node performs a specific function, defines typed inputs/outputs, and can be composed to create reliable automations. Nodes are organized by capability so you can quickly find the right tool for the job.

## AI Processing

AI Processing nodes understand and generate content using language and vision models.
