A node is a single unit on the canvas. Every node has a type that determines what it produces.
Node types
Anatomy
Every generative node has:
- A prompt — the user-authored instructions.
- A model — the AI model that will run.
- Settings specific to its type (aspect ratio, resolution, duration, etc.).
- Input handles — where edges come in.
- Output handles — where edges go out.
- Versions — one per run.
Creating nodes
You can create nodes by:
- Clicking the canvas toolbar.
- Pressing
/ and typing the node type.
- Dragging from the output handle of an existing node (Melius will offer to create a matching downstream node).
- Calling
node_create from the MCP server.
Groups
Group nodes are containers. Select multiple nodes and choose Group to wrap them. Groups are useful for keeping a multi-step pipeline visually tidy.
To rearrange the nodes inside a group, drag-select the group and its contents, then Cmd-click (Ctrl-click on Windows) the group’s label. That drops the group frame from the selection and leaves the nodes inside it selected, so dragging one moves them all without moving the frame. Shift-clicking the label drops the group and everything inside it.
Create a template from a group
Select a group and click Convert to template in its toolbar, or right-click the group and choose Convert to template. The review dialog includes the nodes inside nested groups and lets you configure the template’s inputs and outputs. The original group stays intact.
The group needs at least two content nodes. Groups containing an existing template instance are ineligible because templates cannot nest. Last modified on September 8, 2026
