Image Upscale With Model Batched

ImageUpscaleWithModelBatched

Same as ComfyUI native model upscaling node, but allows setting sub-batches for reduced VRAM usage.

Example

JSON Example

{
  "class_type": "ImageUpscaleWithModelBatched",
  "inputs": {
    "upscale_model": [
      "node_id",
      0
    ],
    "images": [
      "node_id",
      0
    ],
    "per_batch": 16
  }
}

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
upscale_model	UPSCALE_MODEL	required	-	-
images	IMAGE	required	-	-
per_batch	INT	required	min: 1, max: 4096, step: 1	16

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 ImageUpscaleWithModelBatched 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]
