  "inputs": {
    "prompt": "",
    "aspect_ratio": "16:9",
    "guidance": 3,
    "steps": 50,
    "seed": 1234,
    "prompt_upsampling": false
  }
}

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

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 FluxKontextProImageNode 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]
