JSON Example

{
  "class_type": "FluxProUltraImageNode",
  "inputs": {
    "prompt": "",
    "prompt_upsampling": false,
    "seed": 0,
    "aspect_ratio": "16:9",
    "raw": false
  }
}

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	-	""
prompt_upsampling?	BOOLEAN	required	-	false
seed?	INT	required	min: 0, max: 1.84e+19	0
aspect_ratio?	STRING	required	-	"16:9"
raw?	BOOLEAN	required	-	false
image_prompt	IMAGE	optional	-	-
image_prompt_strength?	FLOAT	optional	min: 0, max: 1, step: 0.01	0.1

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 FluxProUltraImageNode 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]
