# Connections

Pass text, images, video or audio between compatible nodes.

**What they do:** Pass text, images, video or audio between compatible nodes.

- The left handle receives an input; the right handle supplies an output.
- Drag an output to an existing node to reuse it there.
- Drag an output onto empty canvas to open **Use this output**, then choose a
  compatible node to create a connected branch.
- One output can feed several nodes. Moving a node changes its position,
  not the content passed through its connections.
- Several text inputs combine in saved connection order, separated by blank
  lines. A generator's own prompt is appended after connected text.
- Type `@` in a prompt and choose a compatible reference to name it and connect
  it. Clicking the resulting tag takes you to the source node.
- Removing a tag removes a connection made by that tag. A connection you
  drew manually can remain and must be removed separately.

Media support depends on the destination. A model may accept a start image,
several image references, audio references, or video references; check its
controls and limits. Connections cannot loop back into their own dependencies.

### Watch the setup

These short demos show setup or existing results. Generation and analysis are
started separately after you review the inputs and displayed price or allowance.

#### Connect existing cards
