# What are Nodes and the Playground?

**Nodes** are the individual AI models and utilities available in Magica. The **Playground** lets you run one Node directly without building a Flow.

Nodes are grouped into categories such as:

* image generation and editing
* video generation and processing
* audio, music, speech, and transcription
* language models
* utilities for routing, extraction, conversion, and media handling

## When to use Nodes

Use Nodes when you know the specific capability you need and want direct control over its inputs.

For example, you might open a video Node, provide a prompt and source image, choose its available settings, and run it from the Playground.

Each Node page can include:

* **Playground** — a no-code form for running the Node
* **API** — developer guidance for running it programmatically
* **History** — previous runs and outputs where available

Use **Flow** when several Nodes need to work together in a repeatable pipeline. Use **Super Agent** when you want to describe an outcome and let Magica choose the tools.
