# Execution Nodes

> Prompt and Workflow nodes – where AI meets orchestration.

## Prompt

Runs a [prompt](/concepts/prompts) within the workflow. Select a prompt and a version (or tag, or latest published) from the dropdowns, map the workflow’s data to the prompt’s placeholders, and the output feeds into whatever comes next.

Configuration includes the [channel](/concepts/memory-and-threads#channels) assignment for memory isolation, and whether to use the prompt’s trigger handle for [loop](/workflow-nodes/loop) re-execution.

## Workflow

Nests an entire [workflow](/concepts/workflows) inside another. Same pattern: select a workflow and version from the dropdowns, map inputs, receive outputs. This is how you build modular, reusable systems – a complex sub-process becomes a single node in a larger pipeline.

Both Prompt and Workflow nodes have a **trigger handle** at the bottom. When a [Loop node](/workflow-nodes/loop) connects to this handle, it re-runs the node with fresh context on each iteration.
