Runway Text to Image

api node/image/Runway

RunwayTextToImageNode

Generate an image from a text prompt using Runway's Gen 4 model. You can also include reference image to guide the generation.

Example

JSON Example

{
  "class_type": "RunwayTextToImageNode",
  "inputs": {
    "prompt": "",
    "ratio": null
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
prompt?	STRING	required	-	""
ratio	COMBO	required	-	-
reference_image?	IMAGE	optional	-	-

Outputs

Index	Name	Type	Is List	Connection Reference
0	IMAGE	IMAGE	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this RunwayTextToImageNode node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• IMAGE (IMAGE): ["5", 0]
